Gottlob Frege Quotes 2152863

Having visual impressions is, of course, necessary for seeing things, but it is not sufficient. What must be added is not anything sensible.

Gottlob Frege Quotes 136092

Gottlob Frege Quotes 1300606

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 ...

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.

Gottlob Frege Quotes 1111879

'Facts, facts, facts,' cries the scientist if he wants to emphasize the necessity of a firm foundation for science. What is a fact? A fact is a thought that is true.

Gottlob Frege Quotes 1387170
