Chrysippus of Soli was a Greek Stoic philosopher. He was a native of Soli, Cilicia, but moved to Athens as a young man, where he became a pupil of the Stoic philosopher Cleanthes. When Cleanthes died, around 230 BC, Chrysippus became the third head of the Stoic school. A prolific writer, Chrysippus expanded the fundamental doctrines of Cleanthes' mentor Zeno of Citium, the founder and first head of the school, which earned him the title of the Second Founder of Stoicism.
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.
Hedone is the Greek word meaning "pleasure." It was an important concept in Ancient Greek philosophy, especially in the Epicurean school. It is also the root of the English word "hedonism".

Sophrosyne is an ancient Greek concept of an ideal of excellence of character and soundness of mind, which when combined in one well-balanced individual leads to other qualities, such as temperance, moderation, prudence, purity, decorum, and self-control. An adjectival form is "sophron."
Panaetius of Rhodes was an ancient Greek Stoic philosopher. He was a pupil of Diogenes of Babylon and Antipater of Tarsus in Athens, before moving to Rome where he did much to introduce Stoic doctrines to the city, thanks to the patronage of Scipio Aemilianus. After the death of Scipio in 129 BC, he returned to the Stoic school in Athens, and was its last undisputed scholarch. With Panaetius, Stoicism became much more eclectic. His most famous work was his On Duties, the principal source used by Cicero in his own work of the same name.
Aristotle first used the term ethics to name a field of study developed by his predecessors Socrates and Plato. In philosophy, ethics is the attempt to offer a rational response to the question of how humans should best live. Aristotle regarded ethics and politics as two related but separate fields of study, since ethics examines the good of the individual, while politics examines the good of the City-State, which he considered to be the best type of community.

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.
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.
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, flourishing life. The Stoics identified the path to achieving it with a life spent practicing certain virtues in everyday life such as courage or temperance 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."

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.

Moral intellectualism or ethical intellectualism is a view in meta-ethics according to which genuine moral knowledge must take the form of arriving at discursive moral judgements about what one should do. One way of understanding this is that doing what is right is a reflection of what any being knows is right. However, it can also be interpreted as the understanding that a rationally consistent worldview and theoretical way of life, as exemplified by Socrates, is superior to the life devoted to a moral life.
