If I have ever made any valuable discoveries, it has been due more to patient attention, than to any other talent.
Not the criticism of individual contemporaries will decide the truth or falsity of these discoveries, but future generations. There are things that are not yet true today, perhaps we dare not find them true, but tomorrow they may be. So every man whose fate it is to go his individual way must proceed with hopefulness and watchfulness, ever conscious of his loneliness and its dangers.
As regards intellectual work it remains a fact, indeed, that great decisions in the realm of thought and momentous discoveries and solutions of problems are only possible to an individual, working in solitude.
