William James Quote

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 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 so.
