Nothing Is Destroyed Until It Is Replaced.

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

The Sacred Formula Of Positivism: Love As A Principle, The Order As A Foundation, And Progress As A Goal.

To Reorganize Society Without God Or King, By The Systematic Culture Of Humanity.

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.

Mathematical Analysis Is... The True Rational Basis Of The Whole System Of Our Positive Knowledge.
