I don't usually comment much elsewhere, but as it's a facet of my blogging that doesn't show up much here, I thought I would just note some of the discussions I've had elsewhere in the recent past (past few weeks).
At "Philosophy, etc." I've been discussing God and possible worlds;
at "Alanyzer" whether an infinite past is possible;
Kant's Antinomies at "What is is like to be a blog?";
at "Assimilatio Dei" whether Newman was an empiricist;
and the Star Trek franchise at "Parableman".
