Theory Attracts Practice As The Magnet Attracts

Sin2 φ Is Odious To Me, Even Though Laplace Made Use Of It; Should It Be Feared That Sin2 φ Might Become Ambiguous, Which Would Perhaps Never Occur, Or At Most Very Rarely When Speaking Of Sin(φ2), Well Then, Let Us Write (sin φ)2, But Not Sin2 φ, Which By Analogy Should Signify Sin (sin φ)

Mathematics Is Concerned Only With The Enumeration And Comparison Of Relations.

It Is Not Knowledge, But The Act Of Learning, Not Possession But The Act Of Getting There, Which Grants The Greatest Enjoyment. When I Have Clarified And Exhausted A Subject, Then I Turn Away From It, In Order To Go Into Darkness Again; The Never-satisfied Man Is So Strange If He Has Completed A Structure, Then It Is Not In Order To Dwell In It Peacefully,but In Order To Begin Another. I Imagine The World Conqueror Must Feel Thus, Who, After One Kingdom Is Scarcely Conquered, Stretches Out His Arms For Others.

Does The Pursuit Of Truth Give You As Much Pleasure As Before? Surely It Is Not The Knowing But The Learning, Not The Possessing But The Acquiring, Not The Being-there But The Getting There That Afford The Greatest Satisfaction. If I Have Exhausted Something, I Leave It In Order To Go Again Into The Dark. Thus Is That Insatiable Man So Strange: When He Has Completed A Structure It Is Not In Order To Dwell In It Comfortably, But To Start Another.

There Are Problems To Whose Solution I Would Attach An Infinitely Greater Importance Than To Those Of Mathematics, For Example Touching Ethics, Or Our Relation To God, Or Concerning Our Destiny And Our Future; But Their Solution Lies Wholly Beyond Us And Completely Outside The Province Of Science.
