[catalogued under 7. Existence / A. Nature of Existence / 1. Nature of Existence]

Full Idea

Some philosophers deny there could have been anything other than what in fact exists, or that anything that exists could have failed to exist. This is developed in very different ways by Wittgenstein (in 'Tractatus'), Lewis and Williamson.

Gist of Idea

Some say what exists must do so, and nothing else could possible exist

A Reaction

This could come in various strengths. A weak version would say that, empirically, that all talk of what doesn't exist is vacuous. A strong necessity (Williamson?) that totally rules out other possible existence is a very odd view.
