“The Plight of History in American Schools”
Diane Ravitch writing in Educational Excellence Network, 1989:
Futuristic novels with a bleak vision of the prospects for the free individual characteristically portray a society in which the dictatorship has eliminated or strictly controls knowledge of the past. In Aldous Huxley’s Brave New World, the regime successfully wages a “campaign against the Past” by banning the teaching of history, closing museums, and destroying historical monuments. In George Orwell’s 1984, the regime routinely alters records of the past; it rewrites newspapers and books to conform to political exigencies, and offending versions are destroyed, dropped “into the memory hole to be devoured by the flames.”
If knowledge of the past does in fact allow us to understand the present and to exercise freedom of mind—as totalitarian societies, both real and fictional, acknowledge by dictating what may be studied or published—then we have cause for concern. The threat to our knowledge of the past arises, however, not from government censorship but from our own indifference and neglect. The erosion of historical understanding among Americans seems especially pronounced in the generation under thirty-five, those schooled during a period in which sharp declines were registered in test scores in virtually every subject of the school curriculum.
Based on the anecdotal complaints of college professors and high school teachers about their students’ lack of preparation, there was reason to suspect that the study of history had suffered as much erosion and dilution as other fields. To test whether students had a secure command of the “foundations of literacy,” the National Assessment of Educational Progress (NAEP) administered the first national assessment of history and literature in the spring of 1986.
One object of the test was to ascertain whether students had ready command of essential background knowledge about American history.
The results were not reassuring. Presumably there is certain background information about American history so fundamental that everyone who goes to school should have learned it by age seventeen (and nearly 80 percent of those who took the assessment were enrolled in the second semester of their high school American history course). In What Do Our 17-Year-Olds Know?, Chester Finn, Jr., and I pointed out that there had never been a test of this kind on a national basis and that there was no way to know whether students were learning more or less about history than in the past.
Nonetheless, we found it disturbing that two-thirds of the sample did not know that the Civil War occurred between 1850 and 1900; that nearly 40 percent did not know that the Brown decision held school segregation unconstitutional; that 40 percent did not know that the East Coast of the United States was explored and settled mainly by England and that the Southwest was explored and settled mainly by Spain, that 70 percent did not know that the purpose of Jim Crow laws was to enforce racial segregation, and that 30 percent could not find Great Britain on a map of Europe.
Since the test had never been given before, critics were quick to quarrel with our judgment that student performance was disappointing. Perhaps, they suggested, students thirty or fifty years ago might have done worse on a comparable test. Others complained that the test should also have been given to a representative sample of the adult population, because if adults don’t know such things, then high school students should not be expected to know them either.
Still others complained that we should not expect students to know or care about history because our society does not reward people who value learning, whether teachers or professors. And there were critics who insisted that the test relied too much on factual knowledge, which is insignificant compared to learning how to think. The most repeated criticism was that the results were of no importance because the study of history itself was of no importance, of no utility whatever in the world today. Again and again, the questions were posed, “What can you do with history? What kind of job will it get you?”
Polemics can be both endless and frustrating because there is almost always some truth in every assertion and counter-assertion. Everything the critics said was true to some extent. But it was also true that the assessment revealed that students were not learning some important things they should know about American history. Whether their counterparts in the past knew less, and whether adults today know less, is beside the point. Three wrongs don’t make a right.
Plainly, a significant number of students are not remembering the history that they have studied; they are not integrating it into their repertoire of background knowledge, either as fact or as concept. In reality, as every student of history ought to recognize, facts and concepts are inseparable. Some information is so basic, so essential that all students must know it in order to make sense of new learning. Nor can students be expected to think critically about issues unless they have the background knowledge to support their reasoning. Insisting that facts have a rightful place in the study of history does not mean that history must be learned by rote.
However one learns about the Civil War, however innovative or unorthodox the teacher’s methodology, the student should know that it took place in the latter half of the nineteenth century, not because of the singular importance of that isolated fact, but because that fact connects the events to a particular place in time, to a larger context, and to a chronological setting in which it is possible to make judgments about causes and consequences and relationships among events in the same era.
Was there once a golden age in the study of history? There may have been, but I know of no evidence for it. In 1943, The New York Times reported the results of a test given to seven thousand college freshmen in thirty-six institutions. It was an open-ended test, not a multiple-choice test. Only 45 percent could name four of the specific freedoms guaranteed by the Bill of Rights; fewer than 25 percent could name two achievements of Abraham Lincoln, Thomas Jefferson, Andrew Jackson, or Theodore Roosevelt; less than 15 percent could identify Samuel Gompers as a leader of organized labor or Susan B. Anthony as an advocate of women’s rights; and only 6 percent could name the thirteen original colonies.
Compared to the college freshmen of 1943, today’s high school juniors do well; after all, 50 percent of today’s sample identified Gompers and 69 percent identified Susan B. Anthony. But our test takers had some critical advantages: first, they took a multiple-choice test, which limits their options and jogs their memory with the right answer; second, Gompers and Anthony are included in their high school textbooks, but were not always included in the textbooks of forty years ago; third, the multiple-choice format virtually guarantees that a minimum of 25 percent will guess the right answer.
The search for comparability may be a blind alley. After all, the historical knowledge that seems most important will differ with each generation, because the salient issues are different for each generation. Today, we expect youngsters to learn about the history of civil rights and minorities, and we stress social history as well as political history. On the NAEP test, there were a number of questions about recent history, like Watergate and Sputnik. Such questions obviously could not have been asked forty years ago, and some of them may seem unimportant forty years from now.
The questions we may reasonably ask about history instruction in the schools are whether students are learning what schools are trying to teach them; whether the history that schools are teaching is significant, current, and presented in ways that encourage student engagement; whether enough time is provided to study issues and events in depth and in context; whether students learn to see today’s issues and events in relationship to the past; whether events are studied from a variety of perspectives; whether students understand that the history they study is not “the truth,” but a version of the past written by historians on the basis of analysis and evidence; and whether students realize that historians disagree about how to define the past.
I first became concerned about the condition of history in the schools while visiting about three dozen campuses across the country in 1984-1985, ranging from large public universities to small private liberal arts colleges. Repeatedly, I was astonished by questions from able students about the most elementary facts of American history. At one urban Minnesota campus, none of the thirty students in a course on ethnic relations had ever heard of the Supreme Court’s Brown v. Board of Education decision of 1954.
How were they learning about ethnic relations? Their professor described the previous week’s role-playing lesson. The class had been visited by a swarthy man who described himself as an Iranian, made some provocative statements, and then launched into a tirade, chastising them for being prejudiced against him (in reality, he was an Italo-American from Long Island, and not an Iranian at all). This “lesson” hardly compensated for their ignorance about the history of immigration, of racial minorities, of slavery and segregation, or of legislative and judicial efforts to establish equality in American life.
As a Phi Beta Kappa Visiting Scholar, I lectured at various campuses on the virtues of a liberal education and its importance to society today. After one such speech at a university in the Pacific Northwest, a professor of education insisted that high-school students should concentrate on vocational preparation and athletics, since they had the rest of their lives to learn subjects like history “on their own time.” Time and again, I heard people wonder why even prospective teachers should have a liberal education, particularly if they planned to teach below the high school level. The younger the children, according to the skeptics, the less their teacher needs to know; they seemed to think that knowing and nurturing were incompatible.
In my meetings and talks with students, who were usually the best in the education or the history program, I was surprised to find that most did not recognize allusions to eminent historical figures such as Jane Addams or W.E.B. DuBois. As I traveled, I questioned history professors about whether their students seemed as well prepared today as in the past. None thought they were. Even at such elite institutions as Columbia and Harvard, professors expressed concern about the absence of a common body of reference and allusion to the past; most said their students lacked a sense of historical context and a knowledge of the major issues that had influenced American history. As a professor at Berkeley put it to me, “They have no furniture in their minds. You can assume nothing in the way of prior knowledge. Skills, yes; but not knowledge.”
Those who teach at non-elite institutions perceived an even deeper level of historical illiteracy. Typical were comments by Thomas Kessner, a professor of history at Kingsborough Community College in Brooklyn, New York: “My students are not stupid, but they have an abysmal background in American or any other kind of history.” This gloomy assessment was echoed by Naomi Miller, chair of the history department at Hunter College in New York. “My students have no historical knowledge on which to draw when they enter college,” she told me.
“They have no point of reference for understanding World War I, the Treaty of Versailles, or the Holocaust.” She expressed dismay at her students’ indifference to dates and chronology or causation. “They think that everything is subjective. They have plenty of attitudes and opinions, but they lack the knowledge to analyze a problem.” Professor Miller believes that “we are in danger of bringing up a generation without historical memory. This is a dangerous situation.”
In search of some explanation for these complaints, I visited social studies classes in New York City. In one high school, where most of the three thousand students are black, Hispanic, and/or recent immigrants, a teacher said to me, “Our students don’t see the relevance to their own lives of what a lot of dead people did a long time ago. American studies means more to them than American history.”
I observed a class in American studies, where the lesson for the day was state government, its leaders and their functions. When the teacher asked whether anyone knew what the state attorney general does, a girl answered tentatively, “Isn’t he the one that says on the cigarette box that you shouldn’t smoke because it gives you cancer?” The teacher responded, incorrectly, “Yes, but what else does he do?” The teacher went on, earnestly trying to explain what New York’s secretary of state does (“he keeps the state’s papers”) and to find some way to connect the work of these officials to the students’ daily lives. The youngsters were bored and apathetic. Watching their impassive faces, I thought that a discussion of the Crusades or the Salem witchcraft trials or Nat Turner’s rebellion would be infinitely more interesting, and relevant, to their adolescent minds.
In another American studies class the topic for the day was the Dred Scott decision. Ah, I thought, I will now see how historical issues are dealt with. The class began with ten minutes of confusing discussion about how students would feel if they were drafted and told they had to serve in Vietnam. The teacher seemed to think this was relevant to the students (since it was relevant to her own generation), although it was not clear that the students had any idea what the war in Vietnam was about. What she was trying to do, I finally realized, was to get the students to wonder who is a citizen and how citizenship is defined. It was a worthy aim, but the rest of the lesson shed little light on the meaning of the Dred Scott decision. The students were told he was a slave who had been brought into a free territory and then sued for his freedom; they were also given a brief definition of the Missouri Compromise. With this as background, the teacher divided them into groups, each of which was a miniature Supreme Court, where they would decide whether Dred Scott should be a slave or go free. Ten minutes later, no surprise, each little Supreme Court recommended that Dred Scott should be a free man, and the class ended. They did not learn why Chief Justice Roger B. Taney decided otherwise, nor did they learn the significance of the Dred Scott decision in the antislavery agitation, nor its importance as a precursor to the Civil War. Since the course was law studies, not American history, the students had no background knowledge about sectional antagonisms, about slavery, or about anything else that preceded or followed the Civil War.
When I expressed surprise about the complete absence of traditional, chronological history in the social studies curriculum, the chair of the social studies department said, “What we teach is determined by guidelines from the State Education Department. In the late 1960s the state decided to deemphasize chronological history and to focus instead on topical issues and social science concepts. We followed suit.” A teacher chimed in to explain, “We don’t teach history, because it doesn’t help our students pass the New York State Regents examination in social studies.” This teacher claimed to have compiled a list of concepts that regularly appear on the Regents examinations; his students prepare for the Regents by memorizing the definitions of such terms as “cultural diffusion” and “social mobility.”
What happened to the study of history? Many factors contributed to its dethroning; some relate to the overall American cultural situation, others to specific institutional forces within the schools and changes in the social studies field. Those who claim that American culture devalues history make a strong case. Despite the fervor of history buffs and historical societies, Americans have long been present- and future-oriented. I suspect that it has never been easy to persuade Americans of the importance of understanding the past. Trends in recent years have probably strengthened popular resistance to historical study. Even in the academy, rampant specialization among college faculties has made professors less willing to teach broad survey courses, less concerned about capturing the attention of non-majors or the general public by tackling large questions.
Within the schools, the study of history has encountered other kinds of problems. During the past generation, history was dislodged from its lofty perch as “queen” of the social studies by the proliferation of social sciences, electives, and other courses. Many in the social studies field say that history still dominates the social studies, since almost all students take the traditional one-year high school course in American history, and about half the students take a one-year course in world history. However, even though the high school American history course may be secure, researchers have found “a gradual and persistent decline in requirements, courses and enrollments” in history at the junior high school level, as well as a reduction of requirements and course offerings in world history in high schools. Indeed, the only history course that is well entrenched in the curriculum is the high school survey of American history.
To some teachers, social studies means the study of the social sciences, and many schools offer electives in sociology, political science, economics, psychology, and anthropology. Some see the field as primarily responsible for the study of current social problems. Others see it as a field whose overriding objective is to teach students the essentials of good behavior and good citizenship. Still others declare that the goal of the social studies is to teach critical thinking, or values, or respect for cultural diversity.
Because of the ill-defined nature of the social studies field, it is easily (and regularly) invaded by curricular fads, and it all too often serves as a dumping ground for special-interest programs. Whenever state legislatures or interest groups discover an unmet need, a new program is pushed into the social studies curriculum. Each state has its own pet programs, but under the copious umbrella of social studies can be found courses in such subjects as energy education, environmental education, gun-control education, water education, sex education, human rights education, future studies, consumer education, free-enterprise education and a host of other courses prompted by contemporary issues.
This indiscriminate confusion of short-term social goals would have dismayed those historians who first took an active interest in history in the schools. In 1893 a distinguished panel of historians, including the future President Woodrow Wilson, recommended an eight-year course of study in history, beginning in the fifth grade with biography and mythology and continuing in the following years with American history and government, Greek and Roman history, French history, and English history. Criticizing the traditional emphasis on rote learning, the Committee of Ten argued that history should teach judgment and thinking, and should be conjoined with such studies as literature, geography, art, and languages. The historians’ recommendations were aimed at all children, not just the college-bound: “We believe that the colleges can take care of themselves; our interest is in the schoolchildren who have no expectation of going to college, the larger number of whom will not enter even a high school.”
In 1899 the Committee of Seven, a group of historians created by the American Historical Association (AHA), recommended a four-year model high school curriculum: first year, ancient history; second year, medieval and modern European history; third year, English history; and fourth year, American history and government. It was expected that students would read biographies, mythology, legends, and hero tales in the elementary years, and that this reading would provide a foundation for their subsequent study of history. The Committee of Seven’s proposal set a national pattern for American high schools for years to come. Like the Committee of Ten, the Seven believed that history should be the core of general education for all students in a democracy.
This four-year model history curriculum came under increasing attack, however, from the newly emerging field of social studies, whose major purpose (according to a 1918 report known as The Cardinal Principles of Secondary Education) was “social efficiency.” Characteristic of the progressive effort to make education socially useful, the new report, which for decades has been considered the most influential document in American education, rejected those studies that seemed not to contribute directly to the goal of training students to take their place in society.
Moreover, The Cardinal Principles broke sharply with the findings and recommendations of earlier committees. It endorsed differentiated curricula, based on students’ future vocational goals, such as agriculture, business, clerical, industrial, and household arts programs. Much of the history that had been taught had no immediate social utility and thus its advocates had difficulty claiming a place in the curriculum. In the decades that followed, as the curriculum incorporated more courses that seemed socially useful or were intended to teach social skills, the time available for history shrank. Many schools collapsed their courses in ancient history, European history, and English history into a single, and optional, one-year course called “world history” or “Western civilization.”
The new emphasis on short-term social utility also affected the curriculum in the early grades. The various reform reports of the early twentieth century had recommended that young children read exciting stories about remarkable people and events that changed the course of history. In most city and state curricula, children in the early grades studied distant civilizations and read their myths and legends in addition to learning the stories about heroes and the folktales of their own country. They also celebrated holidays and learned about their local community through field trips, an emphasis called “home geography.” But by the 1930s this curriculum began to be replaced by studies of family roles and community helpers. Instead of thrilling biographies and mythology, children read stories about children just like themselves.
The new curriculum for the early grades, called “expanding environments” or “expanding horizons,” was factual and immediate, ousting imaginative historical literature and play from the early grades. Increasingly, time in the early grades was devoted to this fixed pattern: kindergarten, myself; first grade, my family; second grade, my neighborhood; third grade, my city. There was no evidence that children preferred to read about postal workers over tall tales, stories of heroes, or ancient Egyptians. Nonetheless, the new curriculum gradually swept the country, pushing historical content out of the early grades.
Not until the late 1980s did the social studies curriculum in the primary grades attract sustained criticism. According to leading cognitive psychologists, the “expanding environments” approach has no grounding in developmental research. Indeed, there is good reason to believe that it dwells unnecessarily on what the child already knows or does not need to go to school to learn. In 1987, a content analysis of social studies textbooks for the early grades was conducted at the University of Georgia. One of the investigators, Professor A. Guy Larkins, concluded, “If asked to choose between teaching primary-grades social studies with available texts or eliminating social studies from the K-3 curriculum, I would choose the latter. Much of the content in current texts is redundant, superfluous, vacuous, and needlessly superficial.” Larkins also complained that children were reading about taking field trips instead of actually taking field trips, seeing pictures of a generic community rather than investigating their own.
Learning again and again about the roles of family members and community helpers in the primary years may well be extremely boring for children who are used to watching action-packed stories on television and seeing dramatic events on the evening news. The me-centered curriculum fails to give children a sense of other times and places, and fails to appeal to their lively imaginations. Children might enjoy the study of history if they began in the early grades to listen to and read lively historical literature, such as myths, legends, hero stories, and true stories about great men and women in their community, state, nation, and world. Not only in the early grades but throughout the kindergarten to twelfth grade sequence, students should read lively narrative accounts of extraordinary events and remarkable people. Present practice seems calculated to persuade young people that social studies is a train of self-evident, unrelated facts, told in a dull manner.
By mid-century most American public schools had adopted a nearly standardized social studies curriculum: Children in kindergarten and the first three grades studied self, home, family, neighborhood, and community; children in fourth grade studied state history; in fifth grade, American history; in sixth grade, world cultures; seventh grade, world geography; eighth grade, American history; ninth grade, civics or world cultures; tenth grade, world history; eleventh grade, American history; twelfth grade, American government. While there have been many variations from district to district, this has been the dominant social studies curriculum for the last fifty years. Most cities and states follow the model for the early grades, teach one year of American history in elementary school and again in junior high school, and require a single year of American history for high school graduation. Most, however, do not require the study of world history in the high school years.
Despite this format’s persistent emphasis on social relevance and student interest, surveys have repeatedly shown that students find social studies to be less interesting and less important than their other school subjects. Why is this field, whose intrinsic human interest is so compelling, so often perceived as boring? There are many possible answers, including the compendious, superficial, and dull textbooks students are assigned to read. But the curricular pattern itself must be in some measure at fault, as it forces repetition of courses on the one hand and too little time for study in depth on the other. Both problems are surefire formulas for dullness, and curriculum planners have been thus far unable to resolve either of them.
When the usual curricular model is followed, American history is taught three times: in the fifth grade, the eighth grade, and the eleventh grade. The question is whether to teach a complete survey course (from pre-Columbian times to the present) at each of the three grade settings. If the survey is taught three times, there is no time to go beyond the textbook, to explore significant questions, to examine original sources or to conduct mock trials or debates. Some districts have broken away from the “coverage” survey by instead teaching major topics and themes in American history, but this approach is clearly insufficient when youngsters fail to understand chronology, the sequence of events, or the causal connections among events.
Another alternative to the survey is to devote each of the three years of American history to a different time period. The usual pattern is that the elementary school course concentrates on exploration and settlement and daily life in the colonies; the junior high course emphasizes the nineteenth century; and the high school year carries the student from the Civil War to the present. The advantage of the latter program is that it allows for time to treat issues in depth, without neglecting chronology. The disadvantage is that it allows no time for mature students to examine the Revolutionary era, when the principles of American government were shaped, or to consider the constitutional conflicts that led to the Civil War. It is also problematic in light of population mobility from state to state, as well as the immigrant influx from other countries, which means that newcomers in the middle or later grades will miss out on important events in the life of the early Republic.
While there is no easy answer to this problem, the history curriculum adopted in California in 1987 attempts to meld the two approaches; each year concentrates on a different time period, but each course begins and ends with an intensive review of critical issues and events. In the world history program, the most pressing problem is time. In most districts where world history is taught, it is studied for only one year, not nearly enough time to encompass the history of the world. New York State adopted a two-year global studies sequence in 1987 (though not strong on history), and California adopted a mandatory three-year world history sequence in the same year. Most other states, however, do not require even one year of world history.
Furthermore, the social studies field is divided about whether world history should emphasize Western Europe or global studies. When the course focuses on Western Europe, it is unified by attention to the evolution of democratic political institutions and ideas, as well as to their betrayal by genocide, war, and racism. When the course is global studies (as, for example, in New York State), equal attention is given to Western Europe, Africa, Latin America, Asia, and other regions. The “Western civilization” course has been criticized by some as “ethnocentric,” while the “global studies” approach has been criticized by others for superficiality, for incoherence, and for minimizing the importance of the West in world history. No matter which approach is taken, a single year is insufficient to study world history.
The difficulty of trying to compress the history of the world into an introductory course is exemplified by one widely-adopted text, in which World War II is reduced to a brief summary and the Holocaust to two sentences: “Many millions of civilians also lost their lives. Six million Jews alone were murdered at Hitler’s orders.”
Does it matter if Americans are ignorant of their past and of the world’s? Does it matter if they know little of the individuals, the events, the ideas, the forces, and the movements that shaped their nation and others? If the study of history is to gain public support and attention,
historians must directly answer the utilitarian challenge. They must be prepared to argue that the study of history is useful in its own terms. Those who study history learn how and why the world came to be what it is, why things change and why they stay the same.Knowledge of history is both useful and necessary for our society because everyone has the right to choose our leaders and to participate in our civic and social life. All citizens, not just the few, are expected to understand major domestic and international issues. Without historical perspective, voters are more likely to be swayed by emotional appeals, by stirring commercials, or by little more than a candidate’s photogenic charisma.
Even between elections, a knowledge of history is vital today for the average citizen and vital for the health of our political system. Politicians and news organizations regularly poll the public to assess their view of domestic and international issues. When public sentiment is clear, the government and the media take heed. When the public is ill-informed or uninterested, policymakers are free to act without the consent of the governed. Americans today require historical background in order to understand complex social and political questions in Latin America, Africa, and elsewhere.
Writers and editors in national newspapers and magazines assume the presence of a historically literate public by alluding without further explanation to historic events and individuals. Without a historically literate public, readily able to understand such references,
newspapers and television journalism will have no choice but to simplify their vocabulary, to reduce their coverage of serious topics, and serve as little more than headline and amusement services, devoid of significant context.Those who have a professional commitment to the study of history have a particular responsibility to improve the way it is taught and learned in the schools. Organizations such as the American Historical Association, the Organization of American Historians (OAH), and the National Council for the Social Studies (NCSS) have a direct responsibility for the quality of history instruction. The teacher-scholar collaboratives sponsored by these organizations are one valuable means to assist professionals in the schools. There are others. For example, professional associations should lobby to ensure that teachers of history have actually studied history in college; in several states, including New York and California, social studies teachers may be certified without ever having studied any history. Professional associations could assist curriculum planners in enriching the study of history at every grade level. The AHA and OAH could provide invaluable support to state curriculum offices that are pressured by powerful interest groups to rewrite or water down the history curriculum; some kind of review mechanism could fend off unreasonable demands.
In 1932, Henry Johnson of Teachers College, Columbia University, wrote a delightful review of the teaching of history throughout the ages, somewhat misleadingly entitled An Introduction to the History of the Social Sciences. Johnson quoted a sixteenth-century Spanish scholar, Juan Vives, to explain why it is valuable to study history: “Where there is history,” wrote Vives, “children have transferred to them the advantages of old men; where history is absent, old men are as children.” Without history, according to Vives, “no one would know anything about his father or ancestors; no one could know his own rights or those of another or how to maintain them; no one would know how his ancestors came to the country he inhabits.” Johnson cited the view of the seventeenth-century French oratorians that “history is a grand mirror in which we see ourselves…The secret of knowing and judging ourselves rightly is to see ourselves in others, and history can make us the contemporaries of all centuries in all countries.”
History will never be restored as a subject of value unless it is detached from vulgar utilitarianism; it should not be expected to infuse morals or patriotism. Properly taught, history teaches the pursuit of truth and understanding; it establishes a context of human life in a particular time and place, relating art, literature, philosophy, law, architecture, language, government, economics, and social life; it portrays the great achievements and terrible disasters of the human race; it awakens youngsters to the universality of the human experience as well as to the particularities that distinguish cultures and societies from one another; it encourages the development of intelligence, civility, and a sense of perspective. It endows its students with a broad knowledge of other times, other cultures, other places. It leaves its students with cultural resources on which they may draw for the rest of their lives. These are values and virtues that are gained through the study of history, values and virtues essential to the free individual exercising freedom of mind. Beyond these, history needs no further justification.
