7. Existence / A. Nature of Existence / 1. Nature of Existence
If 'exist' doesn't express a property, we can hardly ask for its essence [Horsten/Pettigrew]
     Full Idea: If there is indeed no property of existence that is expressed by the word 'exist', then it makes no sense to ask for its essence.
     From: Horsten,L/Pettigrew,R (Mathematical Methods in Philosophy [2014], 2)
     A reaction: As far as I can tell, this was exactly Aristotle's conclusion, so he skirted round the question of 'being qua being', and focused on the nature of objects instead. Grand continental talk of 'Being' doesn't sound very interesting.
7. Existence / A. Nature of Existence / 2. Types of Existence
If 'exist' is ambiguous in 'chairs and numbers exist', that mirrors the difference between chairs and numbers [Fodor]
     Full Idea: People say 'exist' is ambiguous, because of the difference between 'chairs exist' and 'numbers exist'. A reply goes: the difference between the existence of chairs and the existence of numbers is strikingly like the difference between chairs and numbers.
     From: Jerry A. Fodor (Concepts:where cogn.science went wrong [1998], Ch.3)
     A reaction: To say 'numbers are objects which exist' is, to me, either a funny use of 'exist' or a funny use of 'object'. I think I will now vote for the latter. Just as 'real number' was a funny use of 'number', but we seem to have got used to it.
