Viscus Quotes (1 quote)

The source and origin of the nerves is the brain and spinal marrow, and hence some nerves originate from the brain and some from the spinal marrow. Some experts set down the heart as the origin of the nerves and some the hard membrane that envelops the brain; none of them, however, thought it was the liver or any other viscus of that kind Aristotle in particular, and quite a few others, thought that the nerves took origin from the heart.
From De Humani Corporis Fabrica Libri Septem (1543), Book IV, 315, as translated by William Frank Richardson and John Burd Carman, in 'The Nerves Originate From the Brain', On The Fabric of the Human Body: Book III: The Veins And Arteries; Book IV: The Nerves (1998), 160

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
