Francis Collins, the director of the NEH and well-known Christian, has said that agnosticism is a bit of a cop-out. Either be a Christian or be an atheism, but have the guts to make up your mind. I shall argue in a positive way for agnosticism, showing that it can be as vibrant a position as belief or non-belief. It gives you a renewed appreciation of life and the world in which we live.

The reception so far of Kitcher's Vaulting Ambition reminds me of the old saw about the difference between an optimist and a pessimist. Looking at the same glass of water, the former sees it as half full while the latter sees it as half empty. Some have seen Kitcher's book as a vindication of the possibility of an evolutionary science of human behavior; others have seen it as a devastating critique of the most influential efforts to date to construct such (...) a science. As in the joke about the water glass, both assessments have their point. Sociobiology is a research program, not a unified theory. What one can do is test particular hypotheses within this program and see whether they live up to reasonable standards of rigor and evidence. This is what Kitcher does, with great energy and care.

In recent years, philosophers have come to realize that the relationship between science and values raises questions which are both important and not readily answered. It is true that the major figures in that tradition known as ‘logical empiricism’ appreciated that science always exceeds its empirical grasp and that it is necessary for scientists to be guided and constrained by so-called ‘epistemic values,’ these being values (in the words of one supporter) ‘presumed to promote the truth-like character of science, its (...) character as the most secure knowledge available to us of the world we seek to understand.’ However, these values — such things as internal and external consistency, simplicity, predictive accuracy and fertility, unificatory power (consilience) — were considered special. Inasmuch as they could not be reduced to basic principles of logic — and there were attempts to do this — they were still thought of, in some sense, as beyond the vagaries of human emotion. Their importance was not a function of the individual’s personal inclinations, nor of those of the group, whether this group be understood as a closely knit band of researchers or even up to a complete society.

The debate about the credentials of sociobiology has persisted because scholars have failed to distinguish the varieties of sociobiology and because too little attention has been paid to the details of the arguments that are supposed to support the provocative claims about human social behavior. I seek to remedy both deficiencies. After analysis of the relationships among different kinds of sociobiology and contemporary evolutionary theory, I attempt to show how some of the studies of the behavior of nonhuman animals meet (...) the methodological standards appropriate to evolutionary research. I contend that the efforts of E. O. Wilson, Richard Alexander, Charles Lumsden, and others to generate conclusions about human nature are flawed, both because they apply evolutionary ideas in an unrigorous fashion and because they use dubious assumptions to connect their evolutionary analyses with their conclusions. This contention rests on analyses of many of the major sociobiological proposals about human social behavior, including: differences in sex roles, racial hostility, homosexuality, conflict between parents and adolescent offspring, incest avoidance, the avunculate, alliances in combat, female infanticide, and gene–culture coevolution.Vaulting Ambitionthus seeks to identify what is good in sociobiology, to expose the errors of premature speculations about human nature, and to prepare the way for serious study of the evolution of human social behavior.
