It is idle to talk always of the alternative of reason and faith.

Reason is itself a matter of faith.

It is an act of faith to assert that our thoughts have any relation to reality at all.

If you are merely a sceptic, you must sooner or later ask yourself the question, "Why should _anything_ go right; even observation and deduction?
Why should not good logic be as misleading as bad logic?
They are both movements in the brain of a bewildered ape ?" The young sceptic says, "I have a right to think for myself." But the old sceptic, the complete sceptic, says, "I have no right to think for myself.

I have no right to think at all." There is a thought that stops thought.
