New definition, or transclude into Definition:Valid Argument? --GFauxPas (talk) 13:20, 18 February 2013 (UTC)


 * Is there a difference between a truth preserving argument and a valid one? If there is I can't see it. New definition, though, rather than transclude (although we may change our minds on it) ... if there isn't, then rather than transclude, merge them with an "also known as" section. --prime mover (talk) 13:54, 18 February 2013 (UTC)
