Looking for Spinoza - Joy, Sorrow and the Feeling Brain

In the seventeenth century, the philosopher Spinoza examined the role emotion played in human survival and culture. Yet hundreds of years and many significant scientific advances later, the neurobiological roots of joy and sorrow remain a mystery. Today, we spend countless resources doctoring our feelings with alcohol, prescription drugs, health clubs, therapy, vacation retreats, and other sorts of consumption; still, the inner workings of our minds-what feelings are, how they work, and what they mean-are largely an unexplored frontier.

Secrets of the Cat - Its Lore, Legend and Lives

Affectionate yet aloof, intelligent and inquisitive yet dangerously careless, the more-or-less domesticated house cat intrigues us as no other animal can.

The alien is the creation of a need—man’s need to designate something that is genuinely outside himself, something that is truly nonman, that has no initial relation to man except for the fact that it has no relation. Why man needs the alien is the subject of these essays. For it is through learning to relate to the alien that man has learned to study himself.
