Old ideas are continually being slain by new facts. There is nothing stable in the conclusions of the mind, and it is impossible that there ever should be unless we hold that the universe is made to the measure of the human mind, an assumption for which nothing in the past gives any warrant.

All things are at odds when God sets a thinker loose on the planet

There is a field where all wonderful perfections of microscope and telescope fail, all exquisite niceties of weights and measures, as well as that which is behind them, the keen and driving power of the mind.

Theories that go counter to the facts of human nature are foredoomed.

Pain is the most individualized thing on earth. It is true that it is the great common bond as well, but that realization only comes when it is over. To suffer is to be alone. To watch another suffer is to know the barrier that shuts each of us away by himself Only individuals can suffer.

When the mind withdraws into itself and dispenses with facts it makes only chaos.
