If you liked pizza after Socrates was Greek , which seemed to be the case, then it might be post hoc ergo propter hoc rather than a standard non sequitur. <br><br><br>On a wolfe related topic, I did use logic to think of my changeling reading: either the boy was 15 or 18 in Korea, and the changeless doppelgänger appeared at the same time as his three years older sister. So I knew his birthday was either 1934, creating military problems and one family split in twain in 1945, or 1931, solving two problems and positing two families. External references verified the 1931 date. Logic applies to Wolfe, as does Chekov's gun. <div><br></div><div><br>On Friday, October 17, 2014, Dan'l Danehy-Oakes <<a href="mailto:danldo@gmail.com">danldo@gmail.com</a>> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">All Greeks are men.<div>Socrates is a Greek.</div><div>Therefore, I like pizza.</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Fri, Oct 17, 2014 at 7:38 AM, Norwood, Frederick Hudson <span dir="ltr"><<a href="javascript:_e(%7B%7D,'cvml','NORWOODR@mail.etsu.edu');" target="_blank">NORWOODR@mail.etsu.edu</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

be the only creature in the universe, and modus ponens may really mean, "Thou art God." But these objections can be raised in any discussion whatsoever, and after a while most people stop raising them. If I am sane, and if modus ponens says what I think
it says, then it seems to me bedrock on which to build. Further, if there are cases where A implies B, A is true, and B is false, then that ends the discussion, because every statement is both true and false, and in that case there is no point in saying anything

If you already know that the modus ponens is unprovable, and are familiar with reflexive equality which is axiomatic, why are you bothering to hold up modus ponens as an example of an absolute truth?<br>
