Quote by Frege, Gottlob

"A thought is a proposition which we apprehend."

"The word 'number' is surely not without a sense; but when we have the sentence 'the number of roots of this equation is four', it seems very difficult to give the meaning of the word 'number' here."

"Functions are concepts; concepts are functions."

"A concept is a function whose value is always a truth-value."

"I'm not angry, I'm just disappointed."

"The best things in life are free."

"You can't have everything in life, but you can have what matters most."

"A woman's intuition is rarely wrong."
