There's nothing magic about the precise formulations you see above, and over time we regularly revise them in ways we think make Epicurus' views more clear and understandable.

One of the most helpful ways that you can enhance your own understanding of Epicurus is to follow his advice to Herodotus and prepare your own outline of the philosophy. Don't be surprised to find yourself regularly revising it and shifting the items up and down in order of importance. That is to be expected as your comprehension of the importance of the various issues matures. It will take considerable time to realize the many implications of the fundamental principles. EpicureanFriends.com has an entire section of our forum devoted to helping you draw up your own outline. Check out those resources here.

A Preliminary Word On The Nature Of Pleasure:

Most people who come our way have a correct understanding that Epicurus held the experience of mental pleasure to be as much or more important to us than purely bodily pleasure. Unfortunately, many such people also get the impression that this means that Epicurus advocated a withdrawn or ascetic or passive lifestyle.

Metrodorus Despite Epicurus' emphatic focus on Pleasure as the goal of life, the argument that Epicurus was essentially an ascetic asserts that Epicurus held a counterintuitive definition of pleasure by elevating absence of disturbance (ataraxia) or absence of pain (aponia) as something separate from and more desirable than Pleasure (hedone) itself. Those who maintain this generally argue that Epicurus taught that "resting" (katastematic) pleasures are far more important than the normal "active" (kinetic) pleasures, such as joy and delight, that most people normally cherish.

This argument tends to demoralize and turn off healthy people of active disposition, so if the suggestion that Epicurus was passive, shy, and retiring bothers you (and it should, because it's not true!) EpicureanFriends.com can help show you the error of the ascetic interpretation of Epicurus.

For a grounding on the history of the dispute, start with Boris Nikolsky's article "Epicurus on Pleasure." As Nikolsky explains, the distinction between katastematic and kinetic pleasure was very likely not taught by Epicurus at all, but instead derives from a later Stoic-influenced overlay on Epicurus' teachings. For more detail on what Epicurus really taught about pleasure, consult the chapters on Epicurus in Gosling and Taylor's "The Greeks on Pleasure," especially chapter 19 "Katastematic and Kinetic Pleasure," which shows how Epicurus embraced a normal and regular definition of pleasure as most of us commonly understand it. For further evidence that the ascetic interpretation of Epicurean philosophy contradicts core premises of the philosophy (and therefore cannot be correct!) see the Wentham article "Cicero's Interpretation of Katastematic Pleasure."

If you are concerned that you've heard that Epicurus was passive and retiring, and you know that attitude is not right for you, these articles should dispel any lingering concerns.

When you are ready for more, the best way to reboot your understanding of the philosophy is to consult the most thorough general book on Epicurus, Norman DeWitt's "Epicurus and His Philosophy." DeWitt provides the sweeping overview of Epicurean philosophy that every new student of Epicurus needs to read. In the process of starting from scratch, you'll see that DeWitt presents a comprehensive and coherent overview in which the katastematic - kinetic distinction rates little more than a brief mention. You'll then see why the best record we have of Epicurus' philosophy - the biography by Diogenes Laertius - raises the issue only by stating explicitly that Epicurus endorsed both types of pleasure.
