I don't quite know whether I come down on the side of mathematical truths existing independently of humans, or of them being contingent on the existence of life forms that are capable of understanding them. In what sense did mathematical truths exist ten million years ago when there were no humans? Also I've been thinking a lot lately about modal logic and what kind of statement can be necessarily true, or what kind of entity can be necessarily existent, in all possible worlds. I can only think of mathematical statements and structure as candidates, or in general, closed formal systems with a certain set of axioms. Which means, it seems to me, that a lot of theology and Plantinga-style arguments for God's existence are academic in the most pejorative sense of the word. Anyway, sorry for rambling! Just thought I'd say thanks for posting some food for thought.deathray32http://www.youtube.com/user/deathray32noreply@blogger.comtag:blogger.com,1999:blog-3427479692989285926.post-31789227836742903592012-02-12T22:04:43.770+11:002012-02-12T22:04:43.770+11:00I just watched the first episode of Marcus du Saut...I just watched the first episode of Marcus du Sautoy's <a href="http://www.sbs.com.au/ondemand/video/2195002714/The-Code-Numbers" rel="nofollow">The Code</a>, where he effectively argues that everything is determined by numbers, therefore one could argue that even numbers exist independently of us.<br /><br />They are abstract concepts to us, yet they have so much meaning and are intrinsic to every aspect of the universe's existence, that it's virtually impossible to consider that we invented them.<br /><br />Regards, Paul.Paul P.

In this, I've been influenced by Roger Penrose, in particular his book, <i>The Emperor's New Mind</i>.<br /><br />Regards, Paul.Paul P.
