# Solipsism and the Subject in Tractatus Logico-Philosophicus

The claim that the metaphysical subject does not belong to the world but is a limit of it, and that solipsism, when strictly thought through, coincides with realism.

## Where it surfaces

- [5.5421](https://www.betterreads.dev/discover/tractatus_logico_philosophicus_se/chapters/5-5421): Directly addresses the nature of the subject and the soul, arguing against a composite view.
- [5.6](https://www.betterreads.dev/discover/tractatus_logico_philosophicus_se/chapters/5-6): Implies a subjective boundary where the individual's language defines their world, connecting to solipsistic limits.
- [5.61](https://www.betterreads.dev/discover/tractatus_logico_philosophicus_se/chapters/5-61): Implicitly touches on the subject's perspective, as the limits of the world are also the limits of logic and thought.
- [5.62](https://www.betterreads.dev/discover/tractatus_logico_philosophicus_se/chapters/5-62): Directly addresses solipsism as a truth that shows itself, linking the limits of language to the limits of the world.
- [5.621](https://www.betterreads.dev/discover/tractatus_logico_philosophicus_se/chapters/5-621): The identification of world and life implies the subject's world is its life, a key solipsistic idea.
- [5.63](https://www.betterreads.dev/discover/tractatus_logico_philosophicus_se/chapters/5-63): The proposition 'I am my world' directly expresses the solipsistic identification of the self with the world, and the subject as the limit.
- [5.631](https://www.betterreads.dev/discover/tractatus_logico_philosophicus_se/chapters/5-631): This section directly addresses the non-existence of the thinking subject, showing that the subject is not an entity within the world but a limit.
- [5.632](https://www.betterreads.dev/discover/tractatus_logico_philosophicus_se/chapters/5-632): Directly addresses the nature of the subject as a limit, not an element, of the world.
- [5.633](https://www.betterreads.dev/discover/tractatus_logico_philosophicus_se/chapters/5-633): The passage directly addresses the metaphysical subject and its relation to the world, emphasizing that the subject is not an object within the world.
- [5.64](https://www.betterreads.dev/discover/tractatus_logico_philosophicus_se/chapters/5-64): The chapter directly addresses solipsism, showing that the 'I' reduces to a point and reality remains.
- [5.641](https://www.betterreads.dev/discover/tractatus_logico_philosophicus_se/chapters/5-641): The 'I' as metaphysical subject is the limit of the world, not a part of it, resolving solipsism into a transcendental insight.
