Kass was born in Chicago to Jewish immigrants from Eastern Europe. He described his family as "Yiddish speaking, secular, socialist." NOW with Bill Moyers. Transcript. Bill Moyers Talks with Leon Kass. 7.25.03 | PBS Although his upbringing was not religious, it was moralist: "Morality, not Judaism, was the religion of our home, morality colored progressively pink with socialism, less on grounds of Marxist theory, more out of zeal for social justice and human dignity." He would not begin to explore his religious heritage until later in his career.

Kass enrolled in the University of Chicago at age 15, graduating from the College with a degree in biology in 1958. The College was well-known for its extensive core curriculum, and Kass studied the "great books" then prescribed by Chicago's core. "I became a devotee of liberal education . . . with a special fondness for the Greeks." He graduated from the University of Chicago's medical school in 1962 and, following an internship in medicine at the Beth Israel Hospital in Boston, completed a Ph.D. in biochemistry at Harvard University in 1967, working in the laboratory of Nobel laureate Konrad Bloch.

In 1961, Kass married the former Amy Apfel, a fellow graduate of the College of the University of Chicago. As instructors in the College in later years, they would frequently teach seminars together. Their scholarly collaborations include several articles on marriage and courtship and a reader on the subject. (The Kasses have two married daughters and four granddaughters; they reside in Chicago and Washington.)

Leon and Amy Kass went to Holmes County, Mississippi, in 1965 to do civil rights work. The character of the rural, poor, and uneducated African Americans with whom they lived and worked contrasted with his colleagues at Harvard and other elite universities. It was this experience, he later said, that

caused me to shed my enlightenment faith and ultimately begin a journey in which Jewish thought would ultimately come to play a more prominent part. Why, I wondered then, was there more honor, decency, and dignity among the impoverished and ignorant but church-going black farmers with whom we had lived than among my privileged and educated fellow graduate students at Harvard, whose progressive opinions I shared but whose self-absorption and self-indulgence put me off. If poverty and superstition were the cause of bad character, how to explain this?

After completing his doctorate, Kass conducted molecular biology research for the National Institutes of Health, authoring several scientific papers while serving in the U.S. Public Health Service. His early interest in bioethics was stimulated by Aldous Huxley's Brave New World and C. S. Lewis's The Abolition of Man, both of which he read at the suggestion of Harvey Flaumenhaft. In these books, Kass saw examples of "how the scientific project to master nature could, if we are not careful, lead to our dehumanization, via eugenics, drug-induced contentment, and other transformations of human nature, possibilities already foreseeable in the new biology. . . . Will man remain a creature made in the image of God, aspiring to align himself with the divine, or will he become an artifact created by man in the image of God-knows-what, fulfilling the aspirations only of human will? . . . I soon shifted my career from doing science to thinking about its human meaning."

In 1967, Kass read an article by Joshua Lederberg suggesting that humans could one day be cloned, permitting the perpetuation of the genotypes of geniuses. In a letter to the editor, Kass made a moral case against cloning and suggested that "the programmed reproduction of man will, in fact, dehumanize him." Thus began a second career of writing on bioethics, including essays on organ transplantation, genetic screening, in vitro fertilization, cloning, the conquest of aging, assisted suicide, medical ethics, and biotechnology. Kass was also involved in founding the Hastings Center. In 1970, he left the laboratory at NIH to become the executive director of the Committee on Life Sciences and Social Policy at the National Research Council of the National Academy of Science, which produced the first public document that tried to assess the ethical and social consequences of the coming advances in biotechnology.

As he moved from biology to bioethics, Kass also moved from full-time research into teaching, first at St. John's College from 1972 to 1976, Georgetown University from 1974 to 1976, and at Chicago from 1976 onward. At St. John's, Kass taught in the Great Books program as well as in-depth studies of Aristotle's De Anima and Nicomachean Ethics and Darwin's On the Origin of Species. At the University of Chicago, Kass taught courses across the humanities and sciences, including both undergraduate and graduate seminars in the Nicomachean Ethics, Plato's Symposium and Meno, Lucretius, human passions, science and society, Rousseau's Discourse on the Origin of Inequality, Genesis, Darwinism, Descartes's Discourse on the Method, classical geometry, Tolstoy's War and Peace, marriage and courtship, Exodus, and biotechnology.

Along with his wife and other colleagues, Kass cofounded in 1977 the "Human Being and Citizen" common core course at Chicago, today the most popular humanities core course at Chicago, devoted to the question of what is an excellent human being and what an excellent citizen. In 1983, he, Allan Bloom, and James M. Redfield founded the "Fundamentals: Issues and Texts" program. Kass taught in and chaired this program for eighteen years. He won the University of Chicago's Llewellyn John and Harriet Manchester Quantrell Award for Excellence in Undergraduate Teaching in 1983 and the Amoco Foundation Award for Distinguished Contributions to Undergraduate Teaching in 1993.

As the stem cell controversy brewed in the late 1990s and into 2001, President George W. Bush had to decide whether to allow federal funding for research on stem cells derived from embryos. Many scientists were advocating the removal of limits on embryonic stem cell research, but critics expressed concern about they characterized as the wanton destruction of human life. In an August 2001 speech, Bush announced that he would support funding research on stem cell lines already created--"where the life and death decision has already been made"--but not on lines created by the further destruction of embryos. And because "[e]mbryonic stem cell research is at the leading edge of a series of moral hazards," Bush said, he would create the President's Council on Bioethics, to be led by Kass and with a mandate to "monitor stem cell research, to recommend appropriate guidelines and regulations, and to consider all of the medical and ethical ramifications of biomedical innovation." As the council was appointed and prepared to begin meeting in early 2002, Kass received a great deal of media attention, especially due to his reputation for pessimism and concern about the moral implications of scientific progress with respect to health and life issues. Calling him "the president's philosopher," U.S. News and World Report noted that "he tends to dwell on the dark side of modern medicine. . . . Kass has tried to raise the public's consciousness of emerging technology's risks to values that humanity holds dear." The Council from its inception was charged by Bush to consider these larger questions, well beyond the domain of stem cell research. The first specific task of the Council, according to the executive order creating it, was "to undertake fundamental inquiry into the human and moral significance of developments in biomedical and behavioral science and technology."

The composition of the Council was also subject to controversy. Kass was accused of "stacking the deck" with philosophers, scientists, and public intellectuals likely to oppose "unfettered medical research in the area of stem cells, therapeutic cloning, and reproductive cloning. Given that fact, researchers had better worry a lot about what the Council is likely to recommend to the president." Critics also charged that Kass eliminated those who disagreed with him, such as Elizabeth Blackburn and William May, and replacing them with opponents of cloning. Kass replied to these criticisms by saying that the Council was more intellectually diverse than prior bioethics commissions precisely because it included opponents of abortion. (Previous commissions had "excluded representatives of the right to life movement.") Since Bush had deliberately created the Council to debate and clarify the issues without necessarily reaching consensus, Kass said that he welcomed disagreement within the Council: "This council is easily the most intellectually and ethically diverse of the bioethics commissions to date. We have worked with mutual respect while not papering over our differences. No one who has attended any of our meetings or read the transcripts can believe that we do anything but serious and careful work, without regard to ideology, partisan politics or religious beliefs."

The Council has been renewed by executive order every two years since 2001, and the subjects it considered ranged beyond the stem cell battles during which it was established. Kass sought throughout to develop a "richer" bioethics, attentive to larger human and philosophical questions at the root of bioethical dilemmas, and he lamented that the Council was pigeonholed: "The Council came into existence identified as the 'stem cell council,' and people on all sides of the embryo research debate seem to care more about the Council's views on this subject than about anything else. Not by our choice--and certainly not by mine--the Council was born smack in the middle of 'embryoville,' and it has never been able to leave this highly political field." Despite the public's narrow conception of its work, during Kass's chairmanship, the Council produced five book-length reports, a white paper, and a humanistic reader on ten topics generally neglected in the bioethics literature.

Kass described the Council's work as "public bioethics," rejecting previous approaches that favored government by self-appointed "experts"--scientific or bioethical...and presenting the issues in terms accessible to the broader public and its political representatives. He sought a "richer" inquiry that debates "ends as well as means," and the Council's reports addressed larger human questions, "not merely administrative or regulatory ones." He said that it presented all sides of ethical issues in order to create a more substantive moral discourse. "A proper bioethics must lead public reflection on the ways in which new biotechnologies may affect those things that matter most regarding how human lives are lived," Kass wrote. "This means beginning by reflecting upon the highest human goods and understanding the latest technological advances in this light." Eschewing much of the language and theoretical framework of academic bioethics, Kass drew on literary, philosophical, and theological sources to inform the Council's discussion. At the Council's first meeting, he led a discussion of "The Birth-Mark," a short story by Nathaniel Hawthorne.

Kass stepped down as chairman of the Council in October 2005 and remained a member of the Council until 2007. He returned to positions at the American Enterprise Institute and the University of Chicago.

Biotechnology and medical enhancement

While welcoming biotechnology for its therapeutic promise...to cure disease, relieve suffering, and to restore health and wholeness...Kass worries about its uses for enhancement (boosting capability beyond what is given naturally and even and altering human nature). While biotechnology offers great promise for health care, it has applications for "many other ends, good ones and bad." Biotechnology can be employed to produce "better children, superior performance, ageless bodies, and happy souls." Kass argues that biotechnology may eventually be used as a substitute for virtue, hard work, study, or love in order to "fulfill our deepest human desires," but in the end lowering the reach of those desires only to those objects that can be realized technologically . His worries about biotechnology stem from what he calls "the technological disposition," which transforms the meaning and character of human life by believing that "all aspects of life can be rationally mastered through technique."

Stem cell research

Kass has been a consistent critic of embryo research, including embryonic stem cell research, because of its "exploitation" and "destruction" of nascent human life. Although he claims to be agnostic about the moral standing of an early human embryo, he worries about treating human life, at whatever stage, merely as a natural resource. "There is something deeply repugnant and fundamentally transgressive about such a utilitarian treatment of prospective human life," he writes. But because he recognized the potential of such cells for medical research, he led the President's Council on Bioethics to examine alternative avenues of obtaining pluripotent stem cells: "Pluripotent cells might be obtainable from already dead (not just unwanted or doomed but actually dead) embryos, some of whose individual cells might nonetheless still be viable; from living embryos by nondestructive biopsy; from bioengineered, embryo-like artifacts; and from reprogrammed body cells, taken from children or adults, that are induced to return to the undifferentiated state of pluripotency. . . . We should be hopeful that a technological solution to our moral dilemma might soon be found and that this divisive piece of our recent political history will soon come to an end."

In 2007, in two separate studies, research teams led by James Thomson and Shinya Yamanaka created induced pluripotent stem cells from adult cells, meaning that the destruction of embryos for stem cells might no longer be necessary. In 2009, the reprogramming technique was further improved, as skin cells were returned to pluripotency by the transfer of a few exogeneous genes and without the use of foreign viruses as vectors. Robert P. George praised Kass as the driving intellectual force against embryo-killing and in favor of finding alternative methods of obtaining pluripotent stem cells: "All along, it was Dr. Kass who said that reprogramming methods would, if pursued vigorously, enable us to realize the full benefits of stem cell science while respecting human dignity."

Human cloning

Kass supports a universal ban on the cloning of humans on the grounds that cloning is an affront to morality and human dignity. In a 1997 article in The New Republic entitled "The Wisdom of Repugnance," Kass suggests that we should respect the revulsion most people feel about cloning human beings, just as we respect their supposed revulsion at incest and cannibalism. "In crucial cases," he writes, "repugnance is the emotional expression of deep wisdom, beyond reason's power fully to articulate it." Kass writes that modern ethical discourse, which emphasizes autonomy, equity, and utility, fails to provide the moral guidance that the modern world demands:

Repugnance, here as elsewhere, revolts against the excesses of human willfulness, warning us not to transgress what is unspeakably profound. Indeed, in this age in which everything is held to be permissible so long as it is freely done, in which our given human nature no longer commands respect, in which our bodies are regarded as mere instruments of our autonomous rational wills, repugnance may be the only voice left that speaks up to defend the central core of our humanity. Shallow are the souls that have forgotten how to shudder.

A society that tolerates cloning, Kass writes, "has forgotten how to shudder [and] always rationalizes away the abominable.A society that allows cloning has, whether it knows it or not, tacitly said yes to converting procreation into manufacture and to treating our children as pure projects of our will."

Yet, contrary to the claims of his critics, Kass’s moral views do not rely solely on feelings, and he advances multiple arguments against cloning babies, all centering on his concern for children, family ties, and the dignity of human procreation. He argues that cloning constitutes an "unethical experiment upon the resulting child-to-be"; creates confusions of identity and individuality; "turns begetting into making"; and, by giving parents control over a child's genetic make-up, exacerbates the "dangerous" idea of parental control over children's lives and prospects. "One must never forget that these are human beings upon whom our eugenic or merely playful fantasies are to be enacted," he writes.

A concern for "the natural"

Although he appreciates that human beings are always modifying what is naturally given, Kass worries about the lack of standards for human life in a world in which human nature is treated as utterly malleable and in which the boundaries of human life are all eroded. Kass places "special value on the natural human cycle of birth, procreation and death" and views death as a "necessary and desirable end" and the human and human aspirations that are derived from it. He views human mortality as a blessing in disguise, and he has opposed deliberate efforts to increase maximum human life expectancy in pursuit of bodily immortality. Kass was an early critic of the widespread use of reproductive technologies like in vitro fertilization, partly because he was concerned that their use obscures truths about the essence of human life and society that are embedded in the natural reproductive process. (He later endorsed the marital use of in vitro after Louise Brown was born in 1978.)

Kass sees human cloning as a natural progression from the decoupling of sex and procreation, begun with in vitro fertilization: "Cloning turns out to be the perfect embodiment of the ruling opinions of our new age. Thanks to the sexual revolution, we are able to deny in practice, and increasingly in thought, the inherent procreative teleology of sexuality itself. But, if sex has no intrinsic connection to generating babies, babies need have no necessary connection to sex. . . . For that new dispensation, the clone is the ideal emblem: the ultimate 'single-parent child.'" As in his other writings, Kass emphasizes the connection of reproduction to marriage and family life: "No child conceived with the aid of assisted reproductive technologies should be denied the lineage and biological ties to two parents that all children born 'naturally' have. No child should have to say, 'An embryo was my father.'"

For much of his career, Kass's scholarship moved away from the practical issues of bioethics to issues of human nature and human good, and nearly all of his teaching at Chicago has been about these topics. Yet despite his stated interest in "the natural," Kass does not hold to any traditional teaching of "natural law," and he does not derive any moral rules from nature. Rather, he sees human nature as offering, at most, intimations and "pointings" toward human flourishing and human fulfillment, but pointings in need of both cultural encouragement and cultural restraint if humans are to become the upright animal advertised in his special posture.

In addition to his studies in natural philosophy and philosophical anthropology, Kass has in recent years been teaching and writing about the Hebrew Bible, especially the book of Genesis. In his 2009 Jefferson Lecture, Kass said that he found in the Bible "an account of human life that can more than hold its own with the anthropological and ethical teachings offered by the great poets and philosophers," with "teachings of righteousness, humaneness, and human dignity . . . that were undreamt of in my prior philosophizing." Kass reads the text philosophically, not theologically, in the belief that this text, thoughtfully read, has much to teach everyone...believers and non-believers alike...about the human condition and how it may be improved. His full lengthy commentary on Genesis, based on his teaching of the text over twenty years, is addressed primarily to the "children of skeptics" (such as himself). He concludes:

Long dwelling with the book of Genesis, and ever marveling at its beauty, its profundity, and, above all, its power to illuminate and lift the soul, this exhilarated reader of Genesis stands before it on his intellectual knees, filled with awe and gratitude for a text that makes such insights possible. I dare to hope that, with my book as a companion, other wisdom-seeking readers may enjoy a similar experience.

Kass was named the 2009 Jefferson Lecturer by the National Endowment for the Humanities. The Jefferson Lecture is "the highest honor the federal government bestows for distinguished intellectual and public achievement in the humanities." Kass's lecture, delivered at the Warner Theatre in Washington, D.C. on May 21, 2009. was entitled "Looking for an Honest Man: Reflections of an Unlicensed Humanist". In his lecture, he expressed the view that science has become separated from its humanistic origins and the humanities have lost their connection to metaphysical and theological concerns.

In addition to his teaching awards from the University of Chicago, Kass also received the Harvard Centennial Medal and the Intercollegiate Studies Institute's Gerhard Niemeyer Award in 2003 and the inaugural Bradley Prize from the Lynde and Harry Bradley Foundation in 2004. He has been given honorary degrees by the University of Dallas (1997), the Spertus Institute of Jewish Studies (2001), Carthage College (2002), and Yeshiva University (2003).

Pinker: On Eating Ice Cream in Public

Steven Pinker of the New Republic in an article "The Stupidity of Dignity" ridiculed Kass for the position that people should not eat ice cream cones because it undermined their 'dignity'. The implication was that anyone who was opposed to eating ice cream on purely philosophical groups might be seen as "unconventional" or "out of touch". Pinker raises questions about the fundamental soundness of a world view which would make pronouncements on such issues, and uses the issues to further expand his point that Kass philosophical conclusions are unsound and should not influence public policy .

Kass has written the following on the subject in which he states "it is an embarrassment to human self-command to be caught in the grip of involuntary bodily movements":

Worst of all from this point of view are those more uncivilized forms of eating, like licking an ice cream cone --a catlike activity that has been made acceptable in informal America but that still offends those who know eating in public is offensive.

I fear I may by this remark lose the sympathy of many reader, people who will condescendingly regard as quaint or even priggish the view that eating in the street is for dogs. Modern America's rising tide of informality has already washed out many long-standing traditions -- their reasons long before forgotten -- that served well to regulate the boundary between public and private; and in many quarters complete shamelessness is treated as proof of genuine liberation from the allegedly arbitrary constraints of manners. To cite one small example: yawning with uncovered mouth. Not just the uneducated rustic but children of the cultural elite are now regularly seen yawning openly in public (not so much brazenly or forgetfully as indifferently and "naturally"), unaware that it is an embarrassment to human self-command to be caught in the grip of involuntary bodily movements (like sneezing, belching, and hiccuping and even the involuntary bodily display of embarrassment itself, blushing). But eating on the street -- even when undertaken, say, because one is between appointments and has no other time to eat -- displays in fact precisely such lack of self-control: It beckons enslavement to the belly. Hunger must be sated now; it cannot wait. Though the walking street eater still moves in the direction of his vision, he shows himself as a being led by his appetites. Lacking utensils for cutting and lifting to mouth, he will often be seen using his teeth for tearing off chewable portions, just like any animal. Eating on the run does not even allow the human way of enjoying one's food, for it is more like simple fueling; it is hard to savor or even to know what one is eating when the main point is to hurriedly fill the belly, now running on empty. This doglike feeding, if one must engage in it, ought to be kept from public view, where, even if WE feel no shame, others are compelled to witness our shameful behavior."
