We Are To Admit No More Causes

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

For The Rays, To Speak Properly, Have No Colour. In Them There Is Nothing Else Than A Certain Power And Disposition To Stir Up A Sensation Of This Colour Or That.

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.

Let Me Think... I Wonder If An Anvil Will Drop Like An Apple?

Every Particle Of Matter Is Attracted By Or Gravitates To Every Other Particle Of Matter With A Force Inversely Proportional To The Squares Of Their Distances.
