Marie Francois Xavier Bichat quotes:

Medicine is an incoherent assemblage of incoherent ideas, and is, perhaps, of all the physiological Sciences, that which best shows the caprice of the human mind. What did I say! It is not a Science for a methodical mind. It is a shapeless assemblage of inaccurate ideas, of observations often puerile, of deceptive remedies, and of formulae as fantastically conceived as they are tediously arranged.

Life consists in the sum of the functions, by which death is resisted.

Open up a few corpses: you will dissipate at once the darkness that observation alone could not dissipate.
