Although My Knowledge Grows More And More,

Everybody Thinks Himself So Well Supplied With Common Sense That Even Those Most Difficult To Please. . . Never Desire More Of It Than They Already Have.

The Nature Of Matter, Or Body Considered In General, Consists Not In Its Being Something Which Is Hard Or Heavy Or Coloured, Or Which Affects The Senses In Any Way, But Simply In Its Being Something Which Is Extended In Length, Breadth And Depth.

If I Found Any New Truths In The Sciences, I Can Say That They Follow From, Or Depend On, Five Or Six Principal Problems Which I Succeeded In Solving And Which I Regard As So Many Battles Where The Fortunes Of War Were On My Side.

It Is Best Not To Go On For Great Quest For Truth , It Will Only Make You Miserable

It Is Not Enough To Have A Good Mind. The Main Thing Is To Use It Well.
