that “Every truth is so true that any truth must be false,” and Pessimism that “Where everything is bad it must be good to know the worst,” or “Where all is rotten it is a man’s work to cry stinking fish.” About the Unity of Science I have set down that “Whatever you know it is all one,” and of Introspection that “The one self-knowledge worth having is to know one’s mind.” The reader may judge how far these sentences form a Credo, and he must please himself again as to how seriously he takes a further extract: “To love unsatisfied the world is mystery, a mystery which love satisfied seems to comprehend. The latter is wrong only because it cannot be content without thinking itself right.”
But for some general remarks in justification of metaphysics I may refer to the Introduction.
