Current Perspectives in Philosophy of Biology.

There is something distinctively different about explanation in the biological sciences, as opposed to explanation in the physical sciences. In the former one has functional arguments, arguments making reference to what Aristotle called “final causes.” As in: “The function of the plates on the back of the Stegosaurus was to keep the body at a constant temperature.” Since the Scientific Revolution, such explanations have been forbidden in the physical sciences. Does this then mean that biology is second rate, as is (...) suggested by many including Immanuel Kant? It is argued that the Darwinian mechanism of natural selection explains why there is need of functional explanation in biology and that once this point is grasped, there is no reason to judge biology second rate.

How is moral thinking, ethics, related to evolutionary theorizing? There are two approaches, epitomized by Charles Darwin who works under the metaphor of the world as a machine, and by Herbert Spencer who works under the metaphor of the world as an organism. Although the author prefers the first approach, the aim of this paper is to give a disinterested account of both approaches.

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.

Resource rationality may explain suboptimal patterns of reasoning; but what of “anti-Bayesian” effects where the mind updates in a direction opposite the one it should? We present two phenomena — belief polarization and the size-weight illusion — that are not obviously explained by performance- or resource-based constraints, nor by the authors’ brief discussion of reference repulsion. Can resource rationality accommodate them?
