The philosophy of happiness is the philosophical concern with the existence, nature, and attainment of happiness. Some philosophers believe happiness can be understood as the moral goal of life or as an aspect of chance; indeed, in most European languages the term happiness is synonymous with luck. Thus, philosophers usually explicate on happiness as either a state of mind, or a life that goes well for the person leading it. Given the pragmatic concern for the attainment of happiness, research in psychology has guided many modern-day philosophers in developing their theories.
Ancient Greece
Democritus Democritus (c. 460 – c. 370 BC) is known as the 'laughing philosopher' because of his emphasis on the value of 'cheerfulness'.
Plato
Plato (c. 428 – c. 347 BCE) teaches in the Republic that a life committed to knowledge and virtue will result in happiness and self-realization. To achieve happiness, one should become immune to changes in the material world and strive to gain the knowledge of the eternal, immutable forms that reside in the realm of ideas. The Chariot Allegory from the Phaedrus is possibly Plato’s most important teaching on how to achieve inner happiness. Plato sees societal happiness stemming from citizens treating each other justly, leading virtuous lives, and each fulfilling their social function.
Aristotle
Aristotle (384 – 322 BCE) was considered an ancient Greek scholar in the disciplines of ethics, metaphysics, biology and botany, amongst others. Aristotle described eudaimonia (Greek: εὐδαιμονία) as the goal of human thought and action. Eudaimonia is often translated to mean happiness, but some scholars contend that "human flourishing" may be a more accurate translation. More specifically, eudaimonia (arete, Greek: ἀρετή) refers to an inherently positive and divine state of being in which humanity can actively strive for and achieve. Given that this state is the most positive state for a human to be in, it is often simplified to mean happiness. However, Aristotle's use of the term in Nicomachiean Ethics extends beyond the general sense of happiness. Within the Nicomachean Ethics, Aristotle points to the fact that many aims are really only intermediate aims, and are desired only because they make the achievement of higher aims possible. Therefore, things such as wealth, intelligence, and courage are valued only in relation to other things, while eudaimonia is the only thing valuable by itself. Aristotle regarded virtue as necessary for a person to be happy and held that without virtue the most that may be attained is contentment. Within Aristotelian ethics, achieving virtue involves asking the question "how should I be" rather than "what should I do". A fully virtuous person is described as achieving eudaimonia, and therefore would be undeniably happy.
Cynics
Antisthenes (c. 445 – c. 365 BCE), often regarded as the founder of Cynicism, advocated an ascetic life lived in accordance with virtue. Xenophon testifies that Antisthenes had praised the joy that sprang "from out of one's soul," and Diogenes Laërtius relates that Antisthenes was fond of saying: "I would rather go mad than feel pleasure." He maintained that virtue was sufficient in itself to ensure happiness, only needing the strength of a Socrates. He, along with all following Cynics, rejected any conventional notions of happiness involving money, power, and fame, to lead entirely virtuous, and thus happy, lives. Thus, happiness can be gained through rigorous training (askesis, Greek: ἄσκησις) and by living in a way which was natural for humans, rejecting all conventional desires, preferring a simple life free from all possessions. Diogenes of Sinope (c. 412 – c. 323 BCE) is most frequently seen as the perfect embodiment of the philosophy. The Stoics themselves saw him as one of the few, if not only, who have had achieved the state of sage.
Cyrenaics
The Cyrenaics were a school of philosophy established by Aristippus of Cyrene (c. 435 – c. 356 BCE). The school asserted that the only good is positive pleasure, and pain is the only evil. They posit that all feeling is momentary so all past and future pleasure have no real existence for an individual, and that among present pleasures there is no distinction of kind. Claudius Aelianus, in his Historical Miscellany, writes about Aristippus:
"He recommended that one should concrete on the present day, and indeed on the very part of it in which one is acting and thinking. For only the present, he said, truly belongs to us, and not what has passed by or what we are anticipating: for the one is gone and done with, and it is uncertain whether the other will come to be" Some immediate pleasures can create more than their equivalent of pain. The wise person should be in control of pleasures rather than be enslaved to them, otherwise pain will result, and this requires judgement to evaluate the different pleasures of life.
Pyrrho Pyrrho (c. 360 – c. 270 BCE) founded Pyrrhonism, the first Western school of philosophical skepticism. The goal of Pyrrhonist practice is to attain the state of ataraxia (ataraxia, Greek: ἀταραξία) – freedom from perturbation. Pyrrho identified that what prevented people from attaining ataraxia was their beliefs in non-evident matters, i.e., holding dogmas. To free people from belief the ancient Pyrrhonists developed a variety of skeptical arguments.
Epicurus
Epicurus (c. 341 – c. 270 BCE), the founder of Epicureanism, taught that the aim of life was to attain a state of tranquility (ataraxia, Greek: ἀταραξία) and freedom from fear, as well as absence of bodily pain (aponia, Greek: ἀπονία). Toward these ends, Epicurus recommended an ascetic lifestyle, noble friendship, and the avoidance of politics. One aid to achieving happiness is the tetrapharmakos or the four-fold cure:
"Do not fear god, Do not worry about death; What is good is easy to get, and What is terrible is easy to endure." (Philodemus, Herculaneum Papyrus, 1005, 4.9–14).
