Suppose there were an experience machine that would give you any experience you desired. Superduper neuropsychologists could stimulate your brain so that you would think and feel you were writing a great novel, or making a friend, or reading an interesting book. All the time you would be floating in a tank, with electrodes attached to your brain. Should you plug into this machine for life, preprogramming your life experiences?...Of course, while in the tank you won't know that you're there; you'll think that it's all actually happening...Would you plug in?

Wisdom is not just knowing fundamental truths, if these are unconnected with the guidance of life or with a perspective on its meaning. If the deep truths physicists describe about the origin and functioning of the universe have little practical import and do not change our picture of the meaning of the universe and our place within it, then knowing them would not count as wisdom.

The trouble with government regulation of the market is that it prohibits capitalistic acts between consenting adults.

The illegitimate use of a state by economic interests for their own ends is based upon a preexisting illegitimate power of the state to enrich some persons at the expense of others. Eliminate that illegitimate power of giving differential economic benefits and you eliminate or drastically restrict the motive for wanting political influence.

Philosophical argument, trying to get someone to believe something whether he wants to believe it or not, is not, I have held, a nice way to behave towards someone; also it does not fit the original motivation for studying or entering philosophy. That motivation is puzzlement, curiousity, a desire to understand, not a desire to produce uniformity of belief. Most people do not want to become thought-police. The philosophical goal of explanation rather than proof not only is morally better, it is more in accord with one's philosophical motivation.

The scientists often have more unfettered imaginations than current philosophers do. Relativity theory came as a complete surprise to philosophers, and so did quantum mechanics, and so did other things.

What else can matter to us, other than how our lives feel from the inside?
