See my previous post, where I place a special emphasis on the laws of logic. Possibilities (presumably being abstract objects) may also be indispensable, and that's a line of thought that hadn't occurred to me until I read your reply above. I'll formulate the argument in terms of a <i>reductio ad absurdum</i>, this time with the laws of logic.<br /><br />Prove A: Something has necessary existence.<br /><br />Assume ~A: Nothing has necessary existence.<br /><br />~A --> B: If nothing has necessary existence, then the laws of logic are dispensable.<br /><br />~B: The laws of logic are indispensable.<br /><br />Hence, ~~A: by modus tollens.<br /><br />Therefore, A: by negation.<br /><br />Q.E.D.Anonymoushttps://www.blogger.com/profile/07034462951274070391noreply@blogger.comtag:blogger.com,1999:blog-5743370102334877264.post-57138189488225471652013-08-27T10:32:03.577-07:002013-08-27T10:32:03.577-07:00ISTM that in this formulation, 3' follows dire...ISTM that in this formulation, 3' follows directly from 1'---it's not possible for nothing to exist if something (possibilities) necessarily exist. But then the issue isn't so much that you've assumed that possibilities exist as assumed that possibilities exist <i>necessarily</i>.<br /><br />It's an interesting train of thought, though. I've made a recent post about ontological arguments inspired by this post.Anonymoushttps://www.blogger.com/profile/07342391408412861663noreply@blogger.comtag:blogger.com,1999:blog-5743370102334877264.post-17060708715990491742013-08-22T11:57:56.121-07:002013-08-22T11:57:56.121-07:00In fact, the argument can be simplified even furth...In fact, the argument can be simplified even further:<br /><br />1'. Necessarily, possibilities exist. (Premise)<br /><br />2'. It is possible for nothing contingent to exist. (Premise)<br /><br />3'. Hence, it is impossible for nothing to exist. (From 1' and 2')<br /><br />4'. Therefore, something necessary exists. (From 2' and 3')<br /><br />As you mention, though, arguments such as these often have a tendency to assume the conclusion in one of their premises. In both arguments, the existence of possibilities is merely asserted. One could argue for it, however, but I'm not too interested in seeking out arguments for the existence of possibilities.

But then you've clearly assumed what you set out to prove.Anonymoushttps://www.blogger.com/profile/07342391408412861663noreply@blogger.com
