To William Short, October 31, 1819
The letter containing Jefferson's explicit "I too am an Epicurean"
As you say of yourself, I too am an Epicurean. I consider the genuine (not the imputed) doctrines of Epicurus as containing everything rational in moral philosophy which Greece and Rome have left us. Epictetus indeed, has given us what was good of the stoics; all beyond, of their dogmas, being hypocrisy and grimace. Their great crime was in their calumnies of Epicurus and misrepresentations of his doctrines; in which we lament to see the candid character of Cicero engaging as an accomplice.
I take the liberty of observing that you are not a true disciple of our master Epicurus, in indulging the indolence to which you say you are yielding. One of his canons, you know, was that "that indulgence which prevents a greater pleasure, or produces a greater pain, is to be avoided." Your love of repose will lead, in its progress, to a suspension of healthy exercise, a relaxation of mind, an indifference to everything around you, and finally to a debility of body, and hebetude of mind, the farthest of all things from the happiness which the well-regulated indulgences of Epicurus ensure; fortitude, you know is one of his four cardinal virtues. That teaches us to meet and surmount difficulties; not to fly from them, like cowards.
I will place under this a syllabus of the doctrines of Epicurus, somewhat in the lapidary style, which I wrote some twenty years ago.
— Thomas Jefferson
Syllabus of the Doctrines of Epicurus (enclosed with the letter)
- Physical: The Universe eternal. Its parts, great and small, interchangeable. Matter and void alone. Motion inherent in matter, which is weighty and declining, in eternal circulation of the elements of bodies. Gods, an order of beings next superior to man, enjoying in their sphere their own felicities, but not meddling with the concerns of the scale of beings below them.
- Moral: Happiness the aim of life. Virtue the foundation of happiness. Utility the test of virtue. The summum bonum is to be not pained in body, nor troubled in mind – i.e., indolence of body, tranquility of mind. Man is a free agent. Virtue consists in: 1. Prudence, 2. Temperance, 3. Fortitude, 4. Justice.
