Once we have taken the backward step to an abstract view of our whole system of beliefs, evidence, and justification, and seen that it works only, despite its pretensions, by taking the world largely for granted, we are not in a position to contrast all these appearances with an alternative reality. We cannot shed our ordinary responses, and if we could it would leave us with no means of conceiving a reality of any kind.

Life may be not only meaningless but absurd.

If sub specie aeternitatis [from eternity's point of view] there is no reason to believe that anything matters, then that does not matter either, and we can approach our absurd lives with irony instead of heroism or despair.

Philosophy is the childhood of the intellect, and a culture that tries to skip it will never grow up.

Everyone is entitled to commit murder in the imagination once in a while, not to mention lesser infractions.

Reason is universal because no attempted challenge to its results can avoid appealing to reason in the end-by claiming, for example, that what was presented as an argument is really a rationalization. This can undermine our confidence in the original method or practice only by giving us reasons to believe something else, so that finally we have to think about the arguments to make up our minds.

Any reductionist program has to be based on an analysis of what is to be reduced. If the analysis leaves something out, the problem will be falsely posed.
