Every Attempt To Employ Mathematical Methods In The Study Of Chemical Questions Must Be Considered Profoundly Irrational And Contrary To The Spirit Of Chemistry.... If Mathematical Analysis Should Ever Hold A Prominent Place In Chemistry -- An Aberration Which Is Happily Almost Impossible -- It Would Occasion A Rapid And Widespread Degeneration Of That Science.

Every Science Consists In The Coordination Of Facts; If The Different Observations Were Entirely Isolated, There Would Be No Science.

In Mathematics We Find The Primitive Source Of Rationality; And To Mathematics Must The Biologists Resort For Means To Carry Out Their Researches.

The Law Is This: That Each Of Our Leading Conceptions-each Branch Of Our Knowledge-passes Successively Through Three Different Theoretical Conditions: The Theological, Or Fictitious: The Metaphysical, Or Abstract; And The Scientific, Or Positive.
