Because Of Diamond, I Have Had To Begin Much Of The Work Afresh. I Will Not, However, Rid Myself Of Her, Nor Even Punish Her. She Knew Not What She Was Doing, And That Which She Did Was For My Protection And For Love Of My Person. Her Place Remains At My Side Or Against My Feet When I Lie Abed.

I Have Presented Principles Of Philosophy That Are Not, However, Philosophical But Strictly Mathematical-that Is, Those On Which The Study Of Philosophy Can Be Based. These Principles Are The Laws And Conditions Of Motions And Of Forces, Which Especially Relate To Philosophy.
