On this picture Frege's notation system can be seen for basic ideas and signs of mathematical logic, in his work Begriffsschrift. Let it be a freeware picture.
I linked to this picture in an article Begriffsschrift; in English Wikipedia.

Errors
[edit]I don't think this diagram suggests all good translations. In particular, the "judging" line seems to me to obscure several important points. On the left, it's not clear that the "judging" mark is a vertical line applied to the root of a longer expression. And on the right, the equivalent modern notation shouldn't be "p(x) = 1", which is a statement about probability and has nothing to do with what Frege was takling about. instead, it should be the modern "turnstile" symbol. -- Dominus 18:41, 8 Jun 2005 (UTC)
