Quote by Hempel, Carl

"Science is a body of knowledge obtained by methods based upon the assumption that all natural phenomena follow natural laws."

"The function of explanation, whether historical or scientific, is to provide understanding."

"A theory is a well-substantiated explanation of natural phenomena, supported by vast amounts of evidence."

"The aim of science is understanding, not mere description."

"The best part of living is knowing you survived."

"The world needs heroes."

"Life is too short to live poorly."

"I'd rather be an optimist and be wrong than a pessimist and be right"
