Hypothesis

"The first objection to Darwinism is that it is only a guess and was never anything more. It is called a 'hypothesis,' but the word 'hypothesis,' though euphonious, dignified and high-sounding, is merely a scientific synonym for the old-fashioned word 'guess.' If Darwin had advanced his views as a guess they would not have survived for a year, but they have floated for half a century, buoyed up by the inflated word 'hypothesis.' When it is understood that 'hypothesis' means 'guess,' people will inspect it more carefully before accepting it."
--William Jennings Bryan,
"God and Evolution" (1922)
