>>112Diogenes thought writing and teaching of philosophy were pretentious, and so left no written works. The closest you're going to get is this chapter of "the Lives and Opinions of Eminent Philosophers" by a different ancient philosopher named Diogenes, which covers the Cynical school of philosophy, including Diogenes of Sinope. Only 2 hours but by a kind of obnoxious foreign reader.
https://www.youtube.com/watch?v=iwZ6KhOcpe4Aristotle, however, has most of his corpus available on youtube in audiobook format, and can be found by typing "aristotle audiobook" into the search bar on Youtube. Please be aware also that Diogenes of Sinope and Aristotle have almost perfectly opposite philosophies: Aristotle though the pursuit of knowledge was noble and the political life both natural and noble, while Diogenes thought politics and metaphysics were unnatural and mere pretension.
Here is his Nichomachean Ethics in audiobook. It's a must read, but be forewarned that the reader for this book is insanely boring and kind of annoying. It may be worth looking for other readers. It is ten hours in a single recording.
https://www.youtube.com/watchv=GQhZNy9nkDg&t=3sHere is his Politics. It's a mere 8 hours in a single recording, and so pretty easy to complete. Be aware though that Aristotle believes politics to be only an extension of ethics, and so this book is intended as a sort of part two to his Nichomachean Ethics.
https://www.youtube.com/watch?v=d3gVry2xoOEHere's his Rhetoric. I've actually never read this work, and it's by the same boring reader as the Ethics.
https://www.youtube.com/watch?v=Nt6Ai0FNN70Poetics is 2 hours, and mostly worthwhile
https://www.youtube.com/watch?v=x7g7gr8mqecAristotle has other works - personally found his "On the Generation of Animals" to be a fascinating work on the philosophy of biology, and weirdly enough, actually pretty relevant to modern philosophy of biology, and in an indirect way, to modern ethics. I wrote a seminar paper on the concept of teleology from that work in college. But most /pol/ types are only really interested in ethics and politics, and those are the best parts of Aristotle's works.
Here's his Metaphysics though
