In contrast to 50 years ago, few licensed humanists today embrace any view of the humanities that could in fact justify making them the centerpiece o… - Leon Kass

I have discovered in the Hebrew Bible teachings of righteousness, humaneness, and human dignity—at the source of my parents' teachings of mentschlichkeit—undreamt of in my prior philosophizing. In the idea that human beings are equally God-like, equally created in the image of the divine, I have seen the core principle of a humanistic and democratic politics, respectful of each and every human being, and a necessary correction to the uninstructed human penchant for worshiping brute nature or venerating mighty or clever men. In the Sabbath injunction to desist regularly from work and the flux of getting and spending, I have discovered an invitation to each human being, no matter how lowly, to step outside of time, in imitatio Dei, to contemplate the beauty of the world and to feel gratitude for its—and our—existence. In the injunction to honor your father and your mother, I have seen the foundation of a dignified family life, for each of us the nursery of our humanization and the first vehicle of cultural transmission. I have satisfied myself that there is no conflict between the Bible, rightly read, and modern science, and that the account of creation in the first chapter of Genesis offers "not words of information but words of appreciation," as Abraham Joshua Heschel put it: "not a description of how the world came into being but a song about the glory of the world's having come into being"—the recognition of which glory, I would add, is ample proof of the text's claim that we human beings stand highest among the creatures. And thanks to my Biblical studies, I have been moved to new attitudes of gratitude, awe, and attention. For just as the world as created is a world summoned into existence under command, so to be a human being in that world—to be a mentsch—is to live in search of our ­summons. It is to recognize that we are here not by choice or on account of merit, but as an undeserved gift from powers not at our disposal. It is to feel the need to justify that gift, to make something out of our indebtedness for the opportunity of existence. It is to stand in the world not only in awe of its and our existence but under an obligation to answer a call to a worthy life, a life that does honor to the special powers and possibilities—the divine-likeness—with which our otherwise animal existence has been, no thanks to us, endowed.

To act nobly, a noble heart is not enough. It needs help from a sharp mind. Though the beginnings of ethical virtue lie in habituation, starting in our youth, and though the core of moral virtue is the right-shaping of our loves and hates, by means of praise and blame, reward and punishment, the perfection of character finally requires a certain perfection of the mind.

According to Lewis, the dehumanization threatened by the mastery of nature has, at its deepest cause, less the emerging biotechnologies that might directly denature bodies and flatten souls, and more the underlying value-neutral, soulless, and heartless accounts that science proffers of living nature and of man. By expunging from its account of life any notion of soul, aspiration, and purpose, and by setting itself against the evidence of our lived experience, modern biology ultimately undermines our self-understanding as creatures of freedom and dignity, as well as our inherited teachings regarding how to live — teachings linked to philosophical anthropologies that science has now seemingly dethroned.
