Jacob Moleschott
(9 Aug 1822 - 20 May 1893)

Dutch physiologist and philosopher noted for his belief in the material basis of emotion and thought. For example, he recognized phosphoric lime is mined, used to fertilize his wheat, which nourishes not only the body, but also the human brain. Thus “No thought without phosphorus!”

Science Quotes by Jacob Moleschott (3 quotes)

Ohne Phosphor, Kein Gedanke.
Without phosphorus there would be no thought.
— Jacob Moleschott
From Lehre der Nahrungsmittel (1850), 115. (The title translates as Science of Food.) Some sources—incorrectly—attribute these words to Ludwig Büchner, who quoted it but credited it as Jakob “Moleschott’s well-known phrase” in Büchner’s Kraft und Stoff (1856), lxxv; later translated by the author from the 15th German edition in Force and Matter: Or, Principles of the Natural Order of the Universe (1891), 217.
Science quotes on:  |  Phosphorus (16)  |  Thought (959)  |  Without (13)

A force unconnected with matter, hovering loose over matter, is an utterly empty conception. In nitrogen, carbon, hydrogen, oxygen, in sulphur and phosphorus, their several properties have dwelt from all eternity.
— Jacob Moleschott
As quoted in Ludwig Büchner, Force and Matter: Or, Principles of the Natural Order of the Universe (1891), 1.
Science quotes on:  |  All (4105)  |  Carbon (65)  |  Conception (154)  |  Empty (80)  |  Eternity (64)  |  Force (488)  |  Force And Matter (3)  |  Hovering (5)  |  Hydrogen (75)  |  Loose (14)  |  Matter (802)  |  Nitrogen (27)  |  Oxygen (67)  |  Phosphorus (16)  |  Property (168)  |  Sulphur (18)  |  Unconnected (10)

Force is no impelling god, no entity separate from the material substratum ; it is inseparable from matter, is one of its eternal indwelling properties.
— Jacob Moleschott

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
