Streszczenie
The letters that were found after years are the evidence of hard intellectual work that had been
conducted under very infavourable conditions. They refer to the time when Wittgenstein was writing
"Tractatus" while Frege was working on his articles "Thought" and "Negation". Correspondence between
Frege and Wittgenstein prove the common will of communication and mutual understanding. Thus
remains the question why those two close and well known to each other thinkers have not realized
that willingness.
