It is not the brains that matter most, but that which guides them – the character, the heart, generous qualities, progressive ideas.
The scientific man does not aim at an immediate result. He does not expect that his advanced ideas will be readily taken up. His work is like that of the planter — for the future. His duty is to lay the foundation for those who are to come, and point the way. He lives and labors and hopes.
Music, when combined with a pleasurable idea, is poetry; music without the idea is simply music; the idea without the music is prose from its very definitiveness.
Ideas are like rabbits. You get a couple and learn how to handle them, and pretty soon you have a dozen.
Ideas are like fish. If you want to catch little fish, you can stay in the shallow water. But if you want to catch the big fish, you’ve got to go deeper.
You have enemies? Why, it is the story of every man who has done a great deed or created a new idea.
