"For real human beings, the only realism is an embodied realism."

"In asking philosophical questions, we use a reason shaped by the body, a cognitive unconscious to which we have no direct access, and metaphorical thought of which we are largely unaware. The fact that abstract thought is mostly metaphorical means that answers to philosophical questions have always been, and always will be, mostly metaphorical. In itself, that is neither good nor bad. It is simply a fact about the capacities of the human mind. But it has major consequences for every aspect of philosophy. Metaphorical thought is the principal tool that makes philosophical insight possible and that constrains the forms that philosophy can take."

"Fighting is found everywhere in the animal kingdom and nowhere so much as among human animals. Animals fight to get what they want--food, sex, territory, control, etc.--because there are other animals who want the same thing or who want to stop them from getting it. The same is true of human animals, except that we have developed more sophisticated techniques for getting our way. Being "rational animals," we have institutionalized our fighting in a number of ways, one of them being war. Even though we have over the ages institutionalized physical conflict and have employed many of our finest minds to develop more effective means of carrying it out, its basic structure remains essentially unchanged. In fights between brute animals, scientists have observed the practices of issuing challenges for the sake of intimidation, of establishing and defending territory, attacking, defending, counterattacking, retreating, and surrendering. Human fighting involves the same practices. Part of being a rational animal, however, involves getting what you want without subjecting yourself to the dangers of actual physical conflict. As a result, we humans have evolved the social institution of verbal argument. We have arguments all the time in order to try to get what we want, and sometimes these "degenerate" into physical violence."

"In short, philosophical theories are largely the product of the hidden hand of the cognitive unconscious."
