I take the ethical truths to be the stable elements that emerge out of ethical progress and that are retained under further ethical progress.
Philip KitcherWe find in the novella a seamless interweaving of at least two narrative voices, one of which is that of an observer so sympathetic that his language appears to be Aschenbach's own, the other of which is superficially celebratory (except at the moment of moralistic condemnation) but undercuts Aschenbach by means of an ironic detachment.
Philip KitcherAnxieties about ourselves endure. If our proper study is indeed the study of humankind, then it has seemed-and still seems-to many that the study is dangerous. Perhaps we shall find out that we were not what we took ourselves to be. But if the historical development of science has indeed sometimes pricked our vanity, it has not plunged us into an abyss of immorality. Arguably, it has liberated us from misconceptions, and thereby aided us in our moral progress.
Philip KitcherIt is hard to hide our genes completely. However devoted someone may be to the privacy of his genotype, others with enough curiosity and knowledge can draw conclusions from the phenotype he presents and from the traits of his relatives.
