If you want something short, check out the enchiridion. Enchiridion means 'manual', apparently, and is really short/concise though profound and not grasped easily on just a first read<p>The translation I used to use is somewhat archaic so I recently asked here for the best translation of it: <a href="https://www.reddit.com/r/Stoicism/comments/nexdez/best_translation_of_the_enchiridion/" rel="nofollow">https://www.reddit.com/r/Stoicism/comments/nexdez/best_trans...</a><p>I'd take your pick out of these 4: <a href="https://enchiridion.tasuki.org/display:Code:ec,twh,pem,sw/section:meta" rel="nofollow">https://enchiridion.tasuki.org/display:Code:ec,twh,pem,sw/se...</a>
Well, the book is a proper tome, but the section on Stoics is very concise (as is rest of the book, really), so I'd go for "A History of Western Philosophy" by Bertrand Russell.<p>The book also gives a good context on where Stoicism arose, so it might be worthwhile to skim the sections before, though there's no need to get too deep with, say, Aristotle's metaphysics.<p>It's on archive.org: <a href="https://archive.org/details/westernphilosoph035502mbp/page/n1/mode/2up" rel="nofollow">https://archive.org/details/westernphilosoph035502mbp/page/n...</a>
