Our age is characterized by an uncertainty about the na­ture of moral obligations, about what one can hope for in an afterlife, and about the limits of human knowledge. These uncertainties were captured by Immanuel Kant in his Critique of Pure Reason, where he noted three basic human questions: what can we know, what ought we to do, and what can we hope for.
