Frege: Grundlagen

The Foundations of Arithmetic 算術基礎

From the Frege Reader (1997) edited by Michael Beaney, p.90 :

"In this investigation I have adhered to the following fundamental principles:

There must be a sharp separation of the psychological from the logical, the subjective from the objective;

The meaning of a word must be asked for in the context of a proposition, not in isolation;

The distinction between concept and object must be kept in mind.

Beaney comments on J.L. Austin's tranlation (page X) as making Frege "too muck like an Oxford linguistic philosopher." I hope there is another translation in the wiki.
