Tadpole Quotes (3 quotes)
Man is an artifact designed for space travel. He is not designed to remain in his present biologic state any more than a tadpole is designed to remain a tadpole.
…...
The art of healing is an occupation worthy of the best and ablest men, but it is less entirely satisfying to the purely scientific mind than other pursuits of equal dignity. … A physician will have to count the pulses of thirty patients while a physiologist is watching the circulation of a single tadpole.
In 'Professor Jeffries Wyman: A Memorial Outline', The Atlantic Monthly (Nov 1874), 620.
Why it is that animals, instead of developing in a simple and straightforward way, undergo in the course of their growth a series of complicated changes, during which they often acquire organs which have no function, and which, after remaining visible for a short time, disappear without leaving a trace ... To the Darwinian, the explanation of such facts is obvious. The stage when the tadpole breathes by gills is a repetition of the stage when the ancestors of the frog had not advanced in the scale of development beyond a fish.
In The Works of Francis Maitland Balfour (1885), Vol. 1, 702.
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.
