7. Existence / A. Nature of Existence / 3. Being / d. Non-being

22919	A thing which makes no difference seems unlikely to exist [Le Poidevin]
	Full Idea: It is a powerful argument for something's non-existence that it would make absolutely no difference.
	From: Robin Le Poidevin (Travels in Four Dimensions [2003], 02 'Everything')
	A reaction: Powerful, but not conclusive. Neutrinos don't seem to do much, so it isn't far from there to get a particle which does nothing.

7. Existence / A. Nature of Existence / 6. Criterion for Existence

4768	The 'epistemic fallacy' is inferring what does exist from what can be known to exist [Psillos]
	Full Idea: The move from what can (or cannot) be known to exist to what does (or does not) exist has been dubbed the 'epistemic fallacy'.
	From: Stathis Psillos (Causation and Explanation [2002], §1.6)
	A reaction: This should be a standard concept in all philosophical discussion. It is the commonest, simplest, and most profound blunder made by philosophers, and they do it all the time.
