William James

When we should make a choice and we don't, that is already a choice.

There is no greater lie than the misunderstood truth.

Pessimism leads to weakness; optimism to power.

The art of being wise consists in knowing what to turn a blind eye to.

The proof of every truth lies simply in its effectiveness.

Habit is the enormous flywheel of inertia that moves society, its most valuable agent of conservation.

The deepest principle of human character is the longing to be appreciated.

All our scientific and philosophical ideals are altars to the unknown gods.
