What's the opposite of solipsism? because I'm fairly certain only my mind doesn't exist.
@DerKirche idk if a word has been coined yet but some preliminary poking around suggests 'iuctupsism'
@DerKirche
Externism is the term you're looking for. It's the belief that everything exists except the subject, and is the direct inverse of solipsism.

@DerKirche as a younger man I used to delight in trying to convince people I was just a shared hallucination
@ptero I once successfully convinced a large population somebody with my same first name (but a different last name) was actually my younger brother... good kid... wished I remembered his last name
