[Buddhism and Christianity] are in one sense parallel and equal; as a mound and a hollow, as a valley and a hill. There is a sense in which that sublime despair is the only alternative to that divine audacity. It is even true that the truly spiritual and intellectual man sees it as sort of dilemma; a very hard and terrible choice. There is little else on earth that can compare with these for completeness. And he who does not climb the mountain of Christ does indeed fall into the abyss of Buddha.

Progress is the mother of problems.

The trouble with Christianity is, not that its failed, but that it's never been tried . . . not that it can't remake the world, but that it's difficult.

A man does not know what he is saying until he knows what he is not saying.

One of the great disadvantages of hurry is that it takes such a long time.

When people impute special vices to the Christian Church, they seem entirely to forget that the world (which is the only other thing there is) has these vices much more. The Church has been cruel; but the world has been much more cruel. The Church has plotted; but the world has plotted much more. The Church has been superstitious; but it has never been so superstitious as the world is when left to itself.

Science must not impose any philosophy, any more than the telephone must tell us what to say.
