Quote by Hempel, Carl
"Scientific progress depends on our willingness to revise even cherished theories in light of contrary evidence."
More from 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."
