Man is what he believes.

Man is nothing else but what he makes of himself.

Man is what he wills himself to be.

Alle Dinge müssen, der Mensch allein ist das Wesen, welches will.

Der Mensch kann tun was er will; er kann aber nicht wollen was er will.

A man is what he wills himself to be.

A man is literally what he thinks.

Als Körper ist jeder Mensch eins, als Selle nie.

A man is a worker. If he is not that he is nothing.

Der wirklich freie Mensch will nur, was er vermag, und tut nur, was ihm gefällt.

Der Mensch kann tun was er will; er kann aber nicht wollen was er will.

Man can do what he wills but he cannot will what he wills.

What is a man anyhow? what am I? what are you?

Man is a machine, but a very peculiar machine. He is a machine which, in right circumstances, and with right treatment, can know that he is a machine, and having fully realized this, he may find the ways to cease to be a machine.
First of all, what man must know is that he is not one; he is many. He has not one permanent and unchangeable “I” or Ego. He is always different. One moment he is one, another moment he is another, the third moment he is a third, and so on, almost without end.

Kein Mensch ist so wichtig, wie er sich nimmt.
