Frege on Identity
Frege’s most celebrated paper “On Sense and Reference” begins with a puzzle. The sentences “a=a” and “a=b” superficially strike the reader as being different kinds of claims. Among other things, “a=a” seems to be trivially true, even self-evident. On the other hand, “a=b” is an informative sentence. It is of a kind important to many episodes in the history of science. Deeper reflection, however...
متن کاملFrege on Identity Statements

The ...
