## Overview

Roughly speaking, permissivism refers to the stance that everything that can be described without (at least obvious) contradiction exists. Generally speaking, permissivists tend to think the question of whether or not things exist is trivial to answer.

%%ANKI
Basic
What triviality is usually associated with permissivists?
Back: Permissivists tend to think most existence questions admit purely trivial answers.
