As a man's real power grows and his knowledge widens, ever the way he can follow grows narrower: until at last he chooses nothing,but does only and wholly what he must do.

I think there is no way to write about being alone. To write is to tell something to somebody to communicate to others. . . . Solitude is noncommunication, the absence of others, the presence of a self sufficient to itself.

Almost anything carried to a logical extreme becomes depressing.

I think what's happening is, it's all - fantasy, science fiction, ghosts, trolls, whatever - finally being called, being admitted to be literature. The way it used to be, before the Realists and the bloody Modernists took over.

Paradise is for those who make paradise.

It is only when science asks why, instead of simply describing how, that it becomes more than technology. When it asks why, it discovers Relativity. When it only shows how, it invents the atom bomb, and then puts its hands over its eye and says, My God what have I done?

The wise needn't ask, the fool asks in vain.
