Ethical objectivity: The test of time

According to many, evolutionary accounts of ethics undermine the prospects of its objective foundation. By contrast, this paper argues that such evolutionary accounts discredit only the absolutist construal of moral truths as timeless but supports other conceptions of objectivity as tested by time. Insofar as Kantian constructivism addresses the problem of ethical objectivity from the standpoint of temporal rational agents, it is not vulnerable to debunking arguments based on evolutionary explanations. In fact, recent work on evolutionary accounts of reasoning and inferences not only coheres with but it also reinforces the constructivist conception of practical reason as a problem-solving cooperative device apt to temporal and interdependent rational agents.
