The difference between what the most and the least learned people know is inexpressibly trivial in relation to that which is unknown. I assure you, my problems with mathematics are much greater than yours. He who joyfully marches to music in rank and file has already earned my contempt. He has been given a large brain by mistake, since for him the spinal cord would fully suffice.
Imagination is more important than knowledge.
Knowledge is limited. Imagination encircles the world. The important thing is not to stop questioning. Curiosity has its own reason for existing. The most beautiful thing we can experience is the mysterious.
