XIII. To Apolexis, greetings (p. 107)
A reminder that there is always still more to learn, and the great mounds of things we once knew for true but now know to be false is no shame, as long as we’re moving towards truth.

XIV. To Antipater, greetings (p. 109)
Paraphrase:  Antipater, you’ve missed the point.  Duh.  Hugs and kisses, Ps-Diogenes.

XV. To Antipater, greetings (p. 109)
“[One] should demonstrate that the spoken claims conform to the way of life.”  Practice what you preach!

XVI. To Apolexis, greetings (p. 109)
I think this is the first reference to Diogenes jug/jar/barrel we’ve come across.  Inspired by even the snails.

XVII. To Antalcides, greetings (p. 111)
“For while I was present you exhibited nothing worthy of
esteem…”  Ouch.  Basically, “put up or shut up.”

XVIII. To Apolexis, greetings (p. 111)
“The Megarian youths appealed to me to introduce Menodorus
the philosopher to you, a very ridiculous introduction, for you will know that he is a man from his portraits, and from his life and words whether he is also a philosopher. For, in my opinion, the sage provides his own introduction.”

Interesting.  Apparently Menodorus is also called Menas, and might have once been a pirate.

This is part of the Cynic Epistles Reading Plan.
