It really is worth the trouble to invent a new symbol if we can thus remove not a few logical difficulties and ensure the rigour of the proofs. But many mathematicians seem to have so little feeling for logical purity… — Gottlob Frege Copy Share Image
Your discovery of the contradiction caused me the greatest surprise and, I would almost say, consternation, since it has shaken the basis on which I intended to build my arithmetic. — Gottlob Frege Copy Share Image
'Facts, facts, facts,' cries the scientist if he wants to emphasize the necessity of a firm foundation for science. What is a fact? A… — Gottlob Frege Copy Share Image
Having visual impressions is, of course, necessary for seeing things, but it is not sufficient. What must be added is not anything sensible. And… — Gottlob Frege Copy Share Image
...one can hardly deny that mankind has a common store of thoughts which is transmitted from one generation to another. — Gottlob Frege Copy Share Image
It is possible, of course, to operate with figures mechanically, just as it is possible to speak like a parrot: but that hardly deserves… — Gottlob Frege Copy Share Image
The aim of scientific work is truth. While we internally recognise something as true, we judge, and while we utter judgements, we assert. — Gottlob Frege Copy Share Image

Every good mathematician is at least half a philosopher, and every good philosopher is at least half a mathematician. — Gottlob Frege Copy Share Image
I compare arithmetic with a tree that unfolds upwards in a multitude of techniques and theorems while the root drives into the depths. — Gottlob Frege Copy Share Image
A scientist can hardly meet with anything more undesirable than to have the foundations give way just as the work is finished. I was… — Gottlob Frege Copy Share Image
