Ivan Petrovich Pavlov. (№ 449395)

Consider, for example, Newton. After all, he did not part with his idea of gravitation for a minute. Whether he was resting, whether he was alone, whether he presided over a meeting of the Royal Society, etc., he always thought of the same thing. It is clear that his idea pursued him everywhere, every minute. Or the great Helmholtz. He directly in one of his speeches raises the question of how he differs from other people. And he replies that he could not notice any difference, except for one feature, which, it seemed to him, distinguishes him from the rest. It seemed to him that no one else, like him, digs into the subject. He says that when he set himself some task, he could no longer get rid of it, she pursued him constantly until he solved it. You see, therefore, that this persistence, this concentration of thought, is a common feature of the mind from great to small people, a feature that ensures the work of the mind.
