A History of the Civil War, 1861–1865 is a book by James Ford Rhodes written in 1918. It is one of finest examples of plain English writing I have read. How to get your point across unpretentiously.
This short essay by GILBERT MURRAY is the best introduction to Stoicism: http://ia600304.us.archive.org/13/items/thestoicphilosop00mu...
After that, you can dive into:
- EPICTETUS, Discourses, Fragments, Handbook (Oxford World's Classics. It features both Enchiridion and fragments)
- MARCUS AURELIUS, Meditations (Oxford World's Classics)
- Any collection of letters and essays written by SENECA
- PIERRE HADOT, The Inner Citadel (Harvard Press, Translated by Michael Chase)
Don't rush through the material, think deeply about every page you read. Don't forget to understand the life and history of each author. Context is extremely important. Don't let modern sensibilities fill the gaps. If you're looking for a solid introduction to traditional logic, I recommend you Socratic Logic, by Peter Kreeft. Lastly, the only way to truly understand Stoicism is to learn about Socrates and Plato as well.
Henry B. Veatch is one author to look up on this (if you can find affordable used copies of his works). The principle textbook for traditional logic that's still in print is Socratic Logic by Peter Kreeft. Be aware that he is sharply critical of symbolic logic. It's good to be aware of the issues involved; in particular, the paradoxes of material implication. When symbolic logic was being developed, many of its supporters looked disparagingly on traditional logic. Few logicians take that view, anymore.
Symbolic logic won the fight, but traditional logic won the argument. By the former, I mean that symbolic logic is taught nearly to the exclusion of traditional logic. By the latter, I mean that the objections made by the old guard are seen by everyone as valid and are being addressed by the new logic. For example, in traditional logic, the conclusion follows with real necessity from the premises as an effect follows from a cause. Modern logic has revived the study of modal logic in order to deal such things as necessity and possibility.
Furthermore, while symbolic logic is superior for mathematical proofs and technical philosophy, traditional syllogistic logic is better suited for everyday life and verbal arguments; it is the Newtonian mechanics of logic.
