Whenever a man thinks something is beyond his capability, he necessarily thinks so, and by this belief he is so conditioned that he really cannot do what he thinks he cannot do. For while thinking that he cannot do this or that, he is not determined to do it, and consequently it is impossible that he should do it.
The capacity for directed thinking I call intellect; the capacity for passive or undirected thinking I call intellectual intuition.
If a person does not believe himself capable of doing the best things in the world, then he starts to create the worst things.[Не признавая того, что он может творить наилучшее, человек неизбежно творит наихудшее.]
Courage. I know now that man is capable of great deeds. But if he isn’t capable of a great emotion, well, he leaves me cold.
