I Feign No Hypotheses.

Thus Far I Have Explained The Phenomena Of The Heavens And Of Our Sea By The Force Of Gravity, But I Have Not Yet Assigned A Cause To Gravity. Indeed, This Force Arises From Some Cause That Penetrates As Far As The Centers Of The Sun And Planets Without Any Diminution Of Its Power To Act, And That Acts Not In Proportion To The Quantity Of The Surfaces Of The Particles On Which It Acts (as Mechanical Causes Are Wont To Do) But In Proportion To The Quantity Of Solid Matter, And Whose Action Is Extended Everywhere To Immense Distances, Always Decreasing As The Squares Of The Distances.

By Such Deductions The Law Of Gravitation Is Rendered Probable, That Every Particle Attracts Every Other Particle With A Force Which Varies Inversely As The Square Of The Distance. The Law Thus Suggested Is Assumed To Be Universally True.

The Changing Of Bodies Into Light, And Light Into Bodies, Is Very Conformable To The Course Of Nature, Which Seems Delighted With Transmutations.

Plato Is My Friend, Aristotle Is My Friend, But My Greatest Friend Is Truth.

To Me There Has Never Been A Higher Source Of Earthly Honor Or Distinction Than That Connected With Advances In Science.
