. . . Newton Was An Unquestioning Believer In An All-wise Creator Of The Universe, And In His Own Inability - Like The Boy On The Seashore - To Fathom The Entire Ocean In All Its Depths. He Therefore Believed That There Were Not Only Many Things In Heaven Beyond His Philosophy, But Plenty On Earth As Well, And He Made It His Business To Understand For Himself What The Majority Of Intelligent Men Of His Time Accepted Without Dispute (to Them It Was As Natural As Common Sense) - The Traditional Account Of The Creation.

Our Design, Not Respecting Arts, But Philosophy, And Our Subject, Not Manual, But Natural Powers, We Consider Chiefly Those Things Which Relate To Gravity, Levity, Elastic Force, The Resistance Of Fluids, And The Like Forces, Whether Attractive Or Impulsive; And Therefore We Offer This Work As Mathematical Principles Of Philosophy; For All The Difficulty Of Philosophy Seems To Consist In This From The Phenomena Of Motions To Investigate The Forces Of Nature, And Then From These Forces To Demonstrate The Other Phenomena.

Are Not All Hypotheses Erroneous, In Which Light Is Supposed To Consist In Pression Or Motion, Propagated Through A Fluid Medium? For In All These Hypotheses The Phaenomena Of Light Have Been Hitherto Explain'd By Supposing That They Arise From New Modifications Of The Rays; Which Is An Erroneous Supposition.
