As for faith: "I have said that faith and force are corollaries, and that mysticism will always lead to the rule of brutality.
The cause of it is contained in the very nature of mysticism.
Reason is the only objective means of communication and of understanding among men; when men deal with one another by means of reason, reality is their objective standard and frame of reference.
But when men claim to possess supernatural means of knowledge, no persuasion, communication or understanding are possible.
Why do we kill wild animals in the jungle? Because no other way of dealing with them is open to us."
