## A Quote by Karl Friedrich Gauss on discovery and reflection

If others would but reflect on mathematical truths as deeply and as continuously as I have, they would make my discoveries.

## A Quote by Karl Friedrich Gauss on doubt, impossibility, lawyers, and proof

I mean the word proof not in the sense of the lawyers, who set two half proofs equal to a whole one, but in the sense of a mathematician, where half proof = 0, and it is demanded for proof that every doubt becomes impossible.

## A Quote by Karl Friedrich Gauss on confession, interest, and work

A reply to Olbers' attempt in 1816 to entice him to work on Fermat's Theorem. I confess that Fermat's Theorem as an isolated proposition has very little interest for me, because I could easily lay down a multitude of such propositions, which one could neither prove nor dispose of. []

## A Quote by Karl Friedrich Gauss on conviction and necessity

I am coming more and more to the conviction that the necessity of our geometry cannot be demonstrated, at least neither by, nor for, the human intellect. . . . Geometry should be ranked, not with arithmetic, which is purely aprioristic, but with mechanics.

## A Quote by Karl Friedrich Gauss on clarity, darkness, imagination, knowledge, learning, order, possessions, satisfaction, and world

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.

## A Quote by Karl Friedrich Gauss on destiny, ethics, future, god, lies, mathematics, problems, science, and solution

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.
