Epicurus: epistemology
• Empiricist• the ultimate source of all knowledge is
information from the senses (see, e.g., http://plato.stanford.edu/entries/rationalism-empiricism/#1.2)
• sensation occurs through “films” of atoms coming off material bodies and entering our bodies

Epicurus: physics• Reality is made up only of matter and void--nothing
immaterial (see http://plato.stanford.edu/entries/epicurus/#3)
• universe is eternal--nothing can emerge from nothing (see http://www.iep.utm.edu/epicur/#H3
• Some material must be eternal, but it’s not large bodies; must be smaller parts
• There are “atoms” as smallest parts of matter, indivisible (or else could dissolve into nothing)
• Atoms exist eternally

Epicurus on the gods & death
• The gods do not control the universe; it works on its own through principles of physics
• There is no such thing as an immaterial, immortal soul
• We should not fear death (“Letter to Menoeceus” para. 125; Principal Doctrines (2))

All of this info about physics, gods, death is to help people live the best life
• Best life has the “greatest good”: pleasure (for oneself)
• ultimate end/goal of all action--everything we do is for the sake of reaching this
• sought as intrinsic good--good in itself, not just as instrumental good (as means to something else good)
• serves as the “standard for judging the goodness of everything” (“Ltr to M,” para 129)

Most pleasurable state: ataraxia• Ataraxia: Lack of physical or mental pain, not
having unfulfilled desires, sense of peace and tranquility (see, e.g., “Letter to M,” para. 128, 132)
• This is a “static” pleasure, as opposed to a “kinetic” one
• “kinetic” pleasures: pleasure gotten while in the act of fulfilling desires
• kinetic pleasures require that one also has pain (desire being fulfilled), and it may take significant work & trouble to keep getting them

How to have the best life
Natural desires
Cultivate and fulfill mainly certain types of desires
Vain desires come from “baseless
opinion” (Pr Doct #29)
UnnecessaryAlways
unnecessary; insatiable;
troublesome to fulfill
(LM, para 131, Pr Doc #15) (e.g., power, wealth,
fame, immortality)
Necessary
Need not bring pain if not fulfilled, b/c can get rid of desire fairly easily; can be troublesome to fulfill (Pr
Doc #26) (e.g., luxurious food & clothing, (sometimes) sex)
Bring pain if not fulfilled; necessary for happiness,
health or life itself; naturally limited & easy to fulfill (LM para 128, Pr Doc #15, 21) (e.g., food, shelter, rest, friendship)
Wednesday, 2 October, 13
How to have the best life
• Aim to fulfill (mostly) natural and necessary desires
• Enjoy plain meals & simple lifestyle (Letter to M, para. 131)
• Fulfill natural and unnecessary desires when it is easy to do so, but don’t cultivate such desires in self (Letter to M, para. 131)
• Don’t fulfill vain desires at all
Wednesday, 2 October, 13
How to have the best life• Be sure to cultivate and preserve friendships (Princ
Doctrines #27-28, 39-40)
• Why would having friends be so important to happiness?
• Note that the value of friendship, like anything else, is for one’s own pleasure
• But it’s possible to get pleasure from really caring about others for themselves, not just b/c having friends is good for you (& genuine care for others is probably necessary for preserving friendship)

How to have the best life
• Live “prudently, honorably, and justly”; “the virtues are inseparable from a happy life” (Letter to M, para 132; also Princ Doctrines #5)
• Justice: living according to agreements in a society (e.g., laws) that actually lead to mutual benefit (Princ Doctr #31-33, 36-38)
• Why can’t one be unjust and happy? (Princ Doctr #34-35)

How can philosophy help us live the best life?
• Not just providing arguments for how to reduce pain/increase pleasure, but also encouraging people to guide their lives by these
• The “principal doctrines” appear to be short sayings that people might be able to remember--keep these things in mind as much as possible so can live by them
• Groups of friends could support/encourage each other to put these ideas into action in their lives
