Tell him to live by yes and no - yes to everything good, no to everything bad.

We are all potentially such sick men. The sanest and best of us are of one clay with lunatics and prison-inmates. And whenever we feel this, such a sense of the vanity of our voluntary career comes over us, that all our morality appears but as a plaster hiding a sore it can never cure, and all our well-doing as the hollowest substitute for that well-being that our lives ought to be grounded in, but alas! are not.

Our beliefs and our attention are the same fact.

Truth happens to an idea. It becomes true, is made true by events. Its verity is in fact an event, a process: the process namely of its verifying itself, its veri-fication. Its validity is the process of its valid-ation.

Man, whatever else he may be, is primarily a practical being, whose mind is given him to aid in adapting him to this world's life

We are mere bundles of habits.
