Thomas Jefferson, letter to Peter Carr (August 19, 1785):
It is time for you now to begin to be choice in your reading; to begin to pursue a regular course in it; and not to suffer yourself to be turned to the right or left by reading any thing out of that course. I have long ago digested a plan for you, suited to the circumstances in which you will be placed. This I will detail to you, from time to time, as you advance. For the present, I advise you to begin a course of antient history, reading every thing in the original and not in translations. First read Goldsmith's history of Greece. This will give you a digested view of that field. Then take up antient history in the detail, reading the following books, in the following order: Herodotus, Thucydides, Xenophontis Hellenica, Xenophontis Anabasis, Arrian, Quintus Curtius, Diodorus Siculus, Justin. This shall form the first stage of your historical reading, and is all I need mention to you now. The next, will be of Roman history*. From that, we will come down to modern history. In Greek and Latin poetry, you have read or will read at school, Virgil, Terence, Horace, Anacreon, Theocritus, Homer, Euripides, Sophocles. Read also Milton's Paradise Lost, Shakspeare, Ossian, Pope's and Swift's works, in order to form your style in your own language. In morality, read Epictetus, Xenophontis Memorabilia, Plato's Socratic dialogues, Cicero's philosophies, Antoninus, and Seneca.
* Livy, Sallust, Caesar, Cicero's epistles, Suetonius, Tacitus, Gibbon.
