Philosophy can be said to consist of three activities: to see the commonsense answer, to get yourself so deeply into the problem that the common sense answer is unbearable, and to get from that situation back to the commonsense answer.

Since social relationships are always ambiguous, since my thought is only a unit, since my thoughts create rifts as much as they unite, since my words establish contacts by being spoken and create isolation by remaining unspoken, since an immense moat separates the subjective certitude that I have for myself from the objective reality that I represent to others, since I never stop finding myself guilty even though I feel I am innocent.

Believers who have formulated such proofs [for God's existence] ... would never have come to believe as a result of such proofs

All I know is what I have words for.
