Man is what be believes.” — Anton Chekhov

A man is literally what he thinks.

Man prefers to believe what he prefers to be true.

Man is what he wills himself to be.

Man is a credulous animal, and must believe something; in the absence of good grounds for belief, he will be satisfied with bad ones.

A man lives by believing something; not by debating and arguing about many things.

What a man thinks of himself, that it is which determines, or rather indicates, his fate.

Every man is what he is, because of the dominating thoughts which he permits to occupy his mind.

A man's religion is the chief fact with regard to him... By religion I do not mean here the church-creed which he professes, the articles of faith which he will sign... We see men of all kinds of professed creeds attain to almost all degrees of worth or worthlessness under each or any of them... but the thing a man does practically believe (and this is often enough without asserting it even to himself, much less to others); the thing a man does practically lay to heart, concerning his vital relations to this mysterious universe, and his duty and destiny there, that is in all cases the primary thing for him, and creatively determines all the rest. That is his religion.

Man is not only that which he conceives himself to be, but that which he wills himself to be...

Man is a being in search of meaning.

A man may imagine things that are false, but he can only understand things that are true.

A man thinks he owns things, and it is he who is owned

man’s beliefs were his own affair, so long as they did not interfere with the liberty of others.
