 This is not to say, however, that the Silloi has no concern for philosophical detail. We have seen that Timon’s remarks about those philosophers of whom he partially approves often point to specific views of theirs as worthy of praise or criticism. Similarly, many of the fragments on philosophers with whom he has no sympathy pick on some central point in their philosophies as material for caricature—Mind in the case of  Anaxagoras,  for example, or the four basic elements in the case of  Empedocles.  The surviving fragments include portraits of most of the major Greek philosophers up to and including Timon’s time; like good political cartoons, they are sharply drawn and often savagely witty. Indeed, it is arguable that the intensity of the implied criticism in these fragments is at odds with the calm demeanor, and the lack of concern with competitive philosophical debate, that Timon elsewhere celebrates in Pyrrho. Timon may have been an effective spokesman for Pyrrho’s outlook, but it is not clear that he entirely succeeds in exemplifying it himself.
