Quote by Hempel, Carl
"The burden of proof lies with claims to knowledge."
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."
