Epicurus was an ancient Greek philosopher and sage who founded Epicureanism, a highly influential school of philosophy. He was born on the Greek island of Samos to Athenian parents. Influenced by Democritus, Aristippus, Pyrrho, and possibly the Cynics, he turned against the Platonism of his day and established his own school, known as "the Garden", in Athens. Epicurus and his followers were known for eating simple meals and discussing a wide range of philosophical subjects. He openly allowed women and slaves to join the school as a matter of policy. Of the over 300 works said to have been written by Epicurus about various subjects, the vast majority have been destroyed. Only three letters written by him—the letters to Menoeceus, Pythocles, and Herodotus—and two collections of quotes—the Principal Doctrines and the Vatican Sayings—have survived intact, along with a few fragments of his other writings. As a result of his work's destruction, most knowledge about his philosophy is due to later authors, particularly the biographer Diogenes Laërtius, the Epicurean Roman poet Lucretius and the Epicurean philosopher Philodemus, as well as the hostile but largely accurate accounts by the Pyrrhonist philosopher Sextus Empiricus, and the Academic Skeptic and statesman Cicero.
Zeno of Citium was a Hellenistic philosopher from Citium, Cyprus. He was the founder of the Stoic school of philosophy, which he taught in Athens from about 300 BC. Based on the moral ideas of the Cynics, Stoicism laid great emphasis on goodness and peace of mind gained from living a life of virtue in accordance with nature. It proved very popular, and flourished as one of the major schools of philosophy from the Hellenistic period through to the Roman era, and enjoyed revivals in the Renaissance as Neostoicism and in the current era as Modern Stoicism.
Epicureanism is a system of philosophy founded around 307 BCE based upon the teachings of Epicurus, an ancient Greek philosopher. Epicurus was an atomist and materialist, following in the steps of Democritus. His materialism led him to religious skepticism and a general attack on superstition and divine intervention. Epicureanism was originally a challenge to Platonism, and its main opponent later became Stoicism. It is a form of hedonism insofar as it declares pleasure to be its sole intrinsic goal. However, the concept that the absence of pain and fear constitutes the greatest pleasure, and its advocacy of a simple life, make it very different from hedonism as colloquially understood.
Antisthenes was a Greek philosopher and a pupil of Socrates. Antisthenes first learned rhetoric under Gorgias before becoming an ardent disciple of Socrates. He adopted and developed the ethical side of Socrates' teachings, advocating an ascetic life lived in accordance with virtue. Later writers regarded him as the founder of Cynic philosophy.
Ancient Greek philosophy arose in the 6th century BC. Philosophy was used to make sense of the world using reason. It dealt with a wide variety of subjects, including astronomy, epistemology, mathematics, political philosophy, ethics, metaphysics, ontology, logic, biology, rhetoric and aesthetics. Greek philosophy continued throughout the Hellenistic period and later evolved into Roman philosophy.
Eudaimonia, sometimes anglicized as eudaemonia or eudemonia, is a Greek word literally translating to the state or condition of 'good spirit', and which is commonly translated as 'happiness' or 'welfare'.
In Ancient Greek philosophy, ataraxia —generally translated as "unperturbedness", "imperturbability", "equanimity", or "tranquility"— is a lucid state of robust equanimity characterized by ongoing freedom from distress and worry. In non-philosophical usage, ataraxia was the ideal mental state for soldiers entering battle. Achieving ataraxia is a common goal for Pyrrhonism, Epicureanism, and Stoicism, but the role and value of ataraxia within each philosophy varies in accordance with their philosophical theories. The mental disturbances that prevent one from achieving ataraxia also vary among the philosophies, and each philosophy has a different understanding as to how to achieve ataraxia.
Virtue ethics is an approach that treats virtue and character as the primary subjects of ethics, in contrast to other ethical systems that put consequences of voluntary acts, principles or rules of conduct, or obedience to divine authority in the primary role.
Eternal return is a philosophical concept which states that time repeats itself in an infinite loop, and that exactly the same events will continue to occur in exactly the same way, over and over again, for eternity.
Summum bonum is a Latin expression meaning the highest or ultimate good, which was introduced by the Roman philosopher Cicero to denote the fundamental principle on which some system of ethics is based — that is, the aim of actions, which, if consistently pursued, will lead to the best possible life. Since Cicero, the expression has acquired a secondary meaning as the essence or ultimate metaphysical principle of Goodness itself, or what Plato called the Form of the Good. These two meanings do not necessarily coincide. For example, Epicurean and Cyrenaic philosophers claimed that the 'good life' consistently aimed for pleasure, without suggesting that pleasure constituted the meaning or essence of Goodness outside the ethical sphere. In De finibus, Cicero explains and compares the ethical systems of several schools of Greek philosophy, including Stoicism, Epicureanism, Aristotelianism and Platonism, based on how each defines the ethical summum bonum differently.
Aristo of Chios, also spelled Ariston, was a Greek Stoic philosopher and colleague of Zeno of Citium. He outlined a system of Stoic philosophy that was, in many ways, closer to earlier Cynic philosophy. He rejected the logical and physical sides of philosophy endorsed by Zeno and emphasized ethics. Although agreeing with Zeno that Virtue was the supreme good, he rejected the idea that morally indifferent things such as health and wealth could be ranked according to whether they are naturally preferred. An important philosopher in his day, his views were eventually marginalized by Zeno's successors.
Ancient Roman philosophy is philosophy as it was practiced in the Roman Republic and its successor state, the Roman Empire. Roman philosophy includes not only philosophy written in Latin, but also philosophy written in Greek in the late Republic and Roman Empire. Important early Latin-language writers include Lucretius, Cicero, and Seneca the Younger. Greek was a popular language for writing about philosophy, so much so that the Roman Emperor Marcus Aurelius chose to write his Meditations in Greek.
Hellenistic philosophy is Ancient Greek philosophy corresponding to the Hellenistic period in Ancient Greece, from the death of Alexander the Great in 323 BC to the Battle of Actium in 31 BC. The dominant schools of this period were the Stoics, the Epicureans and the Skeptics.
Western philosophy refers to the philosophical thought and work of the Western world. Historically, the term refers to the philosophical thinking of Western culture, beginning with the ancient Greek philosophy of the pre-Socratics. The word philosophy itself originated from the Ancient Greek philosophía (φιλοσοφία), literally, "the love of wisdom" Ancient Greek: φιλεῖν phileîn, "to love" and σοφία sophía, "wisdom").

Apatheia, in Stoicism, refers to a state of mind in which one is not disturbed by the passions. It might better be translated by the word equanimity than the word indifference. The meaning of the word apatheia is quite different from that of the modern English apathy, which has a distinctly negative connotation that includes feelings of inertness, indifference, and impassiveness. According to the Stoics, apatheia was the quality that characterized the sage.
Cynicism is a school of thought in ancient Greek philosophy, originating in the Classical period and extending into the Hellenistic and Roman Imperial periods. According to Cynicism, people are reasoning animals and the purpose of life and the way to gain happiness is to achieve virtue, in agreement with nature, following one's natural sense of reason by living simply and shamelessly free from social constraints. The Cynics rejected all conventional desires for wealth, power, glory, social recognition, conformity, and worldly possessions and even flouted such conventions openly and derisively in public.
Stoicism is a school of Hellenistic philosophy that flourished in Ancient Greece and Ancient Rome. The Stoics believed that the practice of virtue is enough to achieve eudaimonia: a well-lived life. The Stoics identified the path to achieving it with a life spent practicing the four virtues in everyday life: wisdom, courage, temperance or moderation, and justice, and living in accordance with nature. It was founded in the ancient Agora of Athens by Zeno of Citium around 300 BC.
A sage, in classical philosophy, is someone who has attained wisdom. The term has also been used interchangeably with a 'good person', and a 'virtuous person'. Among the earliest accounts of the sage begin with Empedocles' Sphairos. Horace describes the Sphairos as "Completely within itself, well-rounded and spherical, so that nothing extraneous can adhere to it, because of its smooth and polished surface." Alternatively, the sage is one who lives "according to an ideal which transcends the everyday."
Ethics is the branch of philosophy that examines right and wrong moral behavior, moral concepts and moral language. Ethics or moral philosophy is a branch of philosophy that "involves systematizing, defending, and recommending concepts of right and wrong behavior". The field of ethics, along with aesthetics, concerns matters of value, and thus comprises the branch of philosophy called axiology.
