“We have different sets of intuitive principles for man-made objects and natural beings, because we are toolmakers and must understand the connection between the shape of objects and their functions. We have social expectations because we need social support. As we shall see, we have moral intuitions because we depend on fair exchange to prosper. In each case, having these cognitive dispositions made our ancestors more successful than others at reproduction, which is precisely why they turned out to be our ancestors.” — Pascal Boyer
