Favorite Quotes: Immanuel Kant

"But pure reason is a sphere so separate and self-contained that we cannot touch a part without affecting all the rest. We can therefore do nothing without first determining the position of each part and its relation to the rest. For inasmuch as our judgment cannot be corrected by anything outside of pure reason, so the validity and use of every part depends upon the relation in which it stands to all the rest within the domain of reason, just as in the structure of an organized body the end of each member can only be deduced from the full conception of the whole. It may, then, be said of such a critique that it is never trustworthy except it be perfectly complete, down to the smallest elements of pure reason. In the sphere of this faculty you can determine either everything or nothing."

-Prolegomena to Any Future Metaphysics (1783), 263

Jonathan Bennett version (https://www.earlymoderntexts.com/assets/pdfs/kant1783.pdf):

"But the domain of pure reason is so •separate from everything else, and so •inter-connected within itself, that we can’t lay a finger on one part without affecting all the others, and can’t build anything there without first determining where each part is and how it relates to the rest. That’s because our judgment •within this domain can’t be corrected by anything •outside it, and so the validity and use of every part of the domain depends on how it relates to all the rest—just as with the structure of an organism we can work out the purpose of each part only from a full conception of the whole. So it can be said that •such a critique shouldn’t be trusted unless it is perfectly complete, down to the smallest elements of pure reason, and that •in the domain of reason you must settle everything—or you’ll settle nothing."
