PHL2026 Frege: Substitution Failure, Indirect Reference, Customary Sense

Rerecording of last year's lecture, which had horrible echo.
Frege on the problem of substitution failure (which we'll see again in your Quine and Saul readings), and his solution involving indirect reference (= customary sense).
This video was recorded in March 2021 and is mainly intended for students taking PHL2026 Mind and Language at Queen's University Belfast.

Is customary sense a indirect reference

[@kwing-yuiwong6482]

Yes, in indirect speech, the customary sense of a word is its indirect reference.
