## Themes in this chapter

Wittgenstein directly critiques the foundational assumptions of Frege and Russell regarding logical constants.

### Nonsense and Meaning

The denial of logical objects implies that many traditional philosophical statements about logic are nonsensical.

## Character check-ins

### Mr. Wittgenstein

Author of the Tractatus, presenting the argument against logical objects.

### Frege

### Bertrand Russell

## Key lines

> Here it becomes clear that there are no such things as “logical objects” or “logical constants” (in the sense of Frege and Russell).

_Wittgenstein asserts the non-existence of logical objects, a key move in his critique of logicism._
