The Business Of Philosophy Is Not To

Reason Must Approach Nature With The View, Indeed, Of Receiving Information From It, Not, However, In The Character Of A Pupil, Who Listens To All That His Master Chooses To Tell Him, But In That Of A Judge, Who Compels The Witnesses To Reply To Those Questions Which He Himself Thinks Fit To Propose. To This Single Idea Must The Revolution Be Ascribed, By Which, After Groping In The Dark For So Many Centuries, Natural Science Was At Length Conducted Into The Path Of Certain Progress.

Natural Science Physics Contains In Itself Synthetical Judgments A Priori, As Principles. ... Space Then Is A Necessary Representation A Priori, Which Serves For The Foundation Of All External Intuitions.

Thoughts Without Content Are Empty, Intuitions Without Concepts Are Blind.

Everything In Nature Acts In Conformity With Law.

All Human Knowledge Begins With Intuitions, Proceeds From Thence To Concepts, And Ends With Ideas.
