Science Quotes by Joseph Leidy (5 quotes)

“Going fishing!” How often the question has been asked by acquaintances, as they have met me, with rod and basket, on an excursion after materials for microscopic study. “Yes!” has been the invariable answer, for it saved much detention and explanation; and now, behold! I offer them the results of that fishing. No fish for the stomach, but, as the old French microscopist Joblet observed, “some of the most remarkable fishes that have ever been seen”; and food-fishes for the intellect.
— Joseph Leidy
From 'Concluding Remarks', Fresh-Water Rhizopods of North America (1879), 295. Leidy explains how actively he pursued his interest in finding new microscopic life forms to examine by frequent exploration of suitable habitats in the neighborhood of Philadelphia, where he lived and taught.

All those things [scientific research] which you would think would recommend me to the trustees my opponent is using against me. I am shamefully abused as being an atheist, an infidel. It has been positively asserted that I seek to make proselytes to infidelity, and that in my writings I have tried to prove that geology overthrows the Mosaic account of the creation. You may judge of my feelings.”
— Joseph Leidy

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
