The Mathematical Thermology Created By Fourier May Tempt Us To Hope That, As He Has Estimated The Temperature Of The Space In Which We Move, Me May In Time Ascertain The Mean Temperature Of The Heavenly Bodies: But I Regard This Order Of Facts As For Ever Excluded From Our Recognition. We Can Never Learn Their Internal Constitution, Nor, In Regard To Some Of Them, How Heat Is Absorbed By Their Atmosphere. We May Therefore Define Astronomy As The Science By Which We Discover The Laws Of The Geometrical And Mechanical Phenomena Presented By The Heavenly Bodies.

If We Do Not Allow Free Thinking In Chemistry Or Biology, Why Should We Allow It In Morals Or Politics?

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