are the results of human ignorance of the reason in nature. If someone is unkind, it is because they are unaware of their own universal reason, which leads to the conclusion of kindness. The solution to evil and unhappiness then, is the practice of Stoic philosophy—to examine one's own judgments and behavior and determine where they diverge from the universal reason of nature.

The doctrine of "things indifferent"
In philosophical terms, things that are indifferent are outside the application of moral law, that is without tendency to either promote or obstruct moral ends. Actions neither required nor forbidden by the moral law, or that do not affect

Spiritual exercise
Philosophy for a Stoic is not just a set of beliefs or ethical claims, it is a way of life involving constant practice and training (or
askesis, see
asceticismAsceticism describes a lifestyle characterized by abstinence from various sorts of worldly pleasures often with the aim of pursuing religious and spiritual goals...

, Marcus Aurelius defines several such practices. For example, in Book II, part 1:
Say to yourself in the early morning: I shall meet today ungrateful, violent, treacherous, envious, uncharitable men. All of these things have come upon them through ignorance of real good and ill... I can neither be harmed by any of them, for no man will involve me in wrong, nor can I be angry with my kinsman or hate him; for we have come into the world to work together...
Prior to Aurelius, Epictetus in his
Discourses distinguished between three topoi: judgement, desire and inclination. According to French philosopher
Pierre HadotPierre Hadot was a French philosopher and historian of philosophy specializing in ancient philosophy, particularly Neoplatonism. Hadot was ordained in 1944 but following Pope Pius XII's Encyclical "Humani Generis" left the priesthood...
, Epictetus identifies these three acts with logic, physics and ethics respectively. Hadot writes that in the Meditations "Each maxim develops either one of these very characteristic
topoi, or two of them or three of them."
The practices of spiritual exercises have been described as influencing those of

by Seamus Mac Suibhne . Parallels between Stoic spiritual exercises and modern cognitive-behavioural therapy have been detailed at length in Robertson's

Social philosophy

cosmopolitanismCosmopolitanism is the ideology that all human ethnic groups belong to a single community based on a shared morality. This is contrasted with communitarian and particularistic theories, especially the ideas of patriotism and nationalism...

They held that external differences such as rank and wealth are of no importance in social relationships. Instead they advocated the brotherhood of humanity and the natural equality of all human beings. Stoicism became the most influential school of the Greco–Roman world, and produced a number of remarkable writers and personalities, such as

and Epictetus.
In particular, they were noted for their urging of clemency toward slaves. Seneca exhorted, "Kindly remember that he whom you call your slave sprang from the same stock, is smiled upon by the same skies, and on equal terms with yourself breathes, lives, and dies."
Stoicism and Christianity
The major difference between the two philosophies is Stoicism's
pantheismPantheism is the view that the Universe and God are identical. Pantheists thus do not believe in a personal, anthropomorphic or creator god. The word derives from the Greek meaning "all" and the Greek meaning "God". As such, Pantheism denotes the idea that "God" is best seen as a process of...
where God is never fully transcendent but always
immanentImmanence refers to philosophical and metaphysical theories of divine presence, in which the divine is seen to be manifested in or encompassing of the material world. It is often contrasted with theories of transcendence, in which the divine is seen to be outside the material world...
. God as the world-creating entity is personalized in Christian thought, but Stoicism equates God with the totality of the universe; the Stoic idea that all being is corporeal was deeply contrary to Christianity. Also, Stoicism, unlike Christianity, does not posit a beginning or end to the universe, nor does it assert that the individual continues to exist beyond death.
Stoicism was later regarded by the Fathers of the Church as a 'pagan philosophy', nonetheless, some of the central philosophical concepts of Stoicism were employed by the early Christian writers. Examples include the terms "
logos' is an important term in philosophy, psychology, rhetoric and religion. Originally a word meaning "a ground", "a plea", "an opinion", "an expectation", "word," "speech," "account," "reason," it became a technical term in philosophy, beginning with Heraclitus ' is an important term in...
", "virtue", "Spirit", and "conscience". But the parallels go well beyond the sharing (or borrowing) of terminology. Both Stoicism and Christianity assert an inner freedom in the face of the external world, a belief in human kinship with Nature (or God), and a sense of the innate depravity—or "persistent evil"—of humankind as well as the futility and temporarity of worldly possessions and attachments. Both encourage
Ascesis with respect to the passions and inferior emotions (viz. lust, envy and anger) so that the higher possibilities of one's humanity can be awakened and developed.
Stoic writings such as the
Meditations of
Marcus Aurelius have been highly regarded by many Christians throughout the centuries. The Stoic ideal of

is accepted to this day as the perfect moral state by the Eastern Orthodox. St. Ambrose of Milan was known for applying Stoic philosophy to his theology.
Modern usage
The word "stoic" commonly refers to someone indifferent to pain, pleasure, grief, or joy. The modern usage as "person who represses feelings or endures patiently" was first cited in 1579 as a
nounIn linguistics, a noun is a member of a large, open lexical category whose members can occur as the main word in the subject of a clause, the object of a verb, or the object of a preposition .Lexical categories are defined in terms of how their members combine with other kinds of...
, and 1596 as an
adjectiveIn grammar, an adjective is a 'describing' word; the main syntactic role of which is to qualify a noun or noun phrase, giving more information about the object signified....
. In contrast to the term "epicurean", the
Stanford Encyclopedia of Philosophy's entry on Stoicism notes, "the sense of the English adjective ‘stoical’ is not utterly misleading with regard to its philosophical origins."
