a. 'Two things fill the mind with ever new and increasing admiration and awe, the oftener and the more steadily we reflect on them: the starry heavens above and the moral law within. ' Thus Kant formulates his attitude to morality (Critique of Practical Reason, p. 260). He draws a sharp distinction between these two objects of admiration. The starry sky, he writes, represents my relationship to the natural, empirical world. Moral law, on the other hand, is of a completely different order. It ' . . . begins from my invisible self, my personality, and exhibits me in a world which has true infinity, but which is traceable only by the understanding and with which I discern that I am not in a merely contingent but in a universal and necessary connection (. . . ). ' (p. 260). So Kant sees morality as a separate metaphysical order opposed to the world of empirical phenomena. Human beings belong to both worlds. According to Kant, the personality derives nothing of value from its relationship with the empirical world. His part in the sensuous world of nature places man on a level with any animal which before long must give back to the rest of nature the substances of which it is made.

Christian Miller presents a new account of moral character. Most of our friends, colleagues, and even family members are not virtuous people. They do not have virtues such as compassion, honesty, or courage. But at the same time, they are not vicious people either. They do not have vices such as cruelty, dishonesty, or cowardice. Instead most people today have characters which do not qualify as either virtuous or vicious. They have many positive moral features, but also many negative ones too. Our characters are decidedly mixed, and are much more complex than we might have thought. On the one hand, many of us would kill an innocent person in a matter of minutes under pressure from an authority figure as part of a psychology study. Or we would pretend to not see someone collapse from an apparent heart attack across the street. Or we would make a wide circle around someone's dropped papers rather than stop to help pick them up. Yet it is also true that many of us would help another person when we are by ourselves and hear sounds of a non-ambiguous emergency in the next room. Or we would come to the aid of a friend when feeling empathy for her need, and do so for altruistic rather than egoistic reasons. In Moral Character: An Empirical Theory Miller outlines a new picture of our moral character which involves what are called Mixed Character Traits. This picture can help make sense of how most of us are less than virtuous people but also morally better than the vicious.

How fragile is our knowledge of morality, compared to other kinds of knowledge? Does knowledge of the difference between right and wrong fundamentally differ from knowledge of other kinds? Sarah McGrath offers new answers to these questions as she explores the possibilities, sources and characteristic vulnerabilities of moral knowledge.

What is empiricism and what could it be? Bas C. van Fraassen, one of the world’s foremost contributors to philosophical logic and the philosophy of science, here undertakes a fresh consideration of these questions and offers a program for renewal of the empiricist tradition. The empiricist tradition is not and could not be defined by common doctrines, but embodies a certain stance in philosophy, van Fraassen says. This stance is displayed first of all in a searing, recurrent critique of metaphysics, and second in a focus on experience that requires a voluntarist view of belief and opinion. Van Fraassen focuses on the philosophical problems of scientific and conceptual revolutions and on the not unrelated ruptures between religious and secular ways of seeing or conceiving of ourselves. He explores what it is to be or not be secular and points the way toward a new relationship between secularism and science within philosophy.

Sam Harris dismantles the most common justification for religious faith--that a moral system cannot be based on science.

This 1788 work, based on belief in the immortality of the soul, established Kant as a vindicator of the truth of Christianity. It offers the most complete statement of his theory of free will.
