Man's Duty Is To Improve

It Is Precisely In Knowing Its Limits That Philosophy Consists.

Both Love Of Mankind, And Respect For Their Rights Are Duties; The Former However Is Only A Conditional, The Latter An Unconditional, Purely Imperative Duty, Which He Must Be Perfectly Certain Not To Have Transgressed Who Would Give Himself Up To The Secret Emotions Arising From Benevolence.

Nature Has Willed That Man Should, By Himself, Produce Everything That Goes Beyond The Mechanical Ordering Of His Animal Existence, And That He Should Partake Of No Other Happiness Or Perfection Than That Which He Himself, Independently Of Instinct, Has Created By His Own Reason.

No State At War With Another State Should Engage In Hostilities Of Such A Kind As To Render Mutual Confidence Impossible When Peace Will Have Been Made.

I Assert That, In Any Particular Natural Science, One Encounters Genuine Scientific Substance Only To The Extent That Mathematics Is Present.
