For the informal logic connoisseurs, the modus tonens (identified by our very own Scott Aikin and co author Robert Talisse) consists in repeating back an interlocutor’s argument in a derisive tone (see also here).Â There is a visual version of that whichÂ has long bothered me.Â It involves posting aÂ jerky lookingÂ photo of theÂ person whose view you derisively or incredulously report (not refute, by the way, and I think this is important).Â This happens in reporting, as the refutation is the picture.Â Let’s provisionally call it the “ad deformem” (against ugly).
Take the above example from Talking Points Memo.Â No doubt there exist lots of pictures of Erickson.Â This one makes him look like a bloviating jerk.Â What did he say?
In many, many animal species, the male and female of the species play complementary roles, with the male dominant in strength and protection and the female dominant in nurture. Itâ€™s the female who tames the male beast. One notable exception is the lion, where the male lion looks flashy but behaves mostly like a lazy beta-male MSNBC producer.
Yes, he certainly deserves to be laughed at for that.Â But I don’t see the relevance of an uncharitable picture.Â I don’t see the relevance of any picture at all, actually, save to identify the mug for the onlooking audience–to distinguish Erickson from George Will for instance.
The argument seems bad enough on its own.Â And I think the uncharitable picture undermines, rather than advances, the report.Â An accurate report ought to be enough to call attention to the appalling view; the picture turns our attention away from that and onto the person with the view.
Naturally these two persons need not always conflict (the ad hominem after all is not always fallacious), but one ought to be judicious in using them.
