I Am Aware That A Philosopher's Ideas

Mathemata Mathematicis Scribuntur Mathematics Is Written For Mathematicians De Revolutionibus

In The Center Of All Rests The Sun. For Who Would Place This Lamp Of A Very Beautiful Temple In Another Or Better Place That This Wherefrom It Can Illuminate Everything At The Same Time? As A Matter Of Fact, Not Unhappily Do Some Call It The Lantern; Others, The Mind And Still Others, The Pilot Of The World. Trismegistus Calls It A "visible God"; Sophocles' Electra, "that Which Gazes Upon All Things." And So The Sun, As If Resting On A Kingly Throne, Governs The Family Of Stars Which Wheel Around.

In The First Book I Shall Describe All The Positions Of The Spheres, Along With The Motions Which I Attribute To The Earth, So That The Book Will Contain As It Were The General Structure Of The Universe. In The Remaining Books I Relate The Motions Of The Remaining Stars, And All The Spheres, To The Mobility Of The Earth, So That It Can Be Thence Established How Far The Motions And Appearances Of The Remaining Stars And Spheres Can Be Saved, If They Are Referred To The Motions Of The Earth.

For I Am Not So Enamoured Of My Own Opinions That I Disregard What Others May Think Of Them.

I Am Aware That A Philosopher's Ideas Are Not Subject To The Judgment Of Ordinary Persons, Because It Is His Endeavour To Seek The Truth In All Things, To The Extent Permitted To Human Reason By God.
