Stoicism (Summary from Wikipedia)
Beginning around 301 BC, Zeno taught philosophy at the Stoa Poikile (Painted Porch), from which his philosophy (Stoicism) got its name. Stoicism laid great emphasis on goodness and peace of mind gained from living a life of virtue in accordance with nature. The universe, in Zeno's view, is God: a divine reasoning entity, where all the parts belong to the whole. The path to Eudaimonia (happiness, blessedness, flourishing) is found in accepting the moment as it presents itself, by not allowing oneself to be controlled by the desire for pleasure or the fear of pain, and by using one's mind to understand the world and to do one's part in nature's plan, and by working together and treating others fairly and justly.
External things such as health, wealth, and pleasure, are not good or bad in themselves, destructive emotions resulted from errors of judgment, an individual's philosophy is not what a person said but how a person behaves. Because "virtue is sufficient for happiness", a sage would be emotionally resilient to misfortune. Epicurus' claimed that "Empty are the words of that philosopher who offers no therapy for human suffering".
Stoicism teaches the development of self-control and fortitude as a means of overcoming destructive emotions. "Virtue consists in a will that is in agreement with Nature." This principle also applies to the realm of interpersonal relationships; "to be free from anger, envy, and jealousy", and to accept even slaves as "equals of other men, because all men alike are products of nature".
Cleanthes opined that the wicked man is "like a dog tied to a cart, and compelled to go wherever it goes". A Stoic of virtue, by contrast, would amend his will to suit the world and remain, in the words of Epictetus, "sick and yet happy, in peril and yet happy, dying and yet happy, in exile and happy, in disgrace and happy", thus positing a completely autonomous individual will. Zeno's ideas developed from those of the Cynics, whose founding father, Antisthenes, had been a disciple of Socrates.
Stoicism became the foremost popular philosophy among the educated elite in the Hellenistic world and the Roman Empire, "Things in our control are opinion, pursuit, desire, aversion, and, in a word, whatever are our own actions. Things not in our control are body, property, reputation, command, and, in a word, whatever are not our own actions."
"The universe itself is God and the universal outpouring of its soul; it is this same world's guiding principle, operating in mind and reason, together with the common nature of things and the totality that embraces all existence. Constantly regard the universe as one living being, having one substance and one soul; and observe how all things have reference to one perception, the perception of this one living being". Marcus Aurelius, Meditations, iv. 40
For the Stoics, reason meant using logic and understanding the processes of nature—the logos or universal divine order and reason, inherent in all things. The four cardinal virtues of Stoic philosophy is derived from the teachings of Plato: Wisdom, Courage, Justice, Temperance
Since right reason is the foundation of both humanity and the universe, it follows that the goal of life is to live according to reason (according to nature). The Stoics did not seek to extinguish emotions; rather, they sought to transform them by a resolute "askēsis" (asceticism) , that enables a person to develop clear judgment and inner calm. Logic, reflection, and focus were the methods of such self-discipline, temperance was split into self-control, discipline, and modesty.
"Follow where reason leads". One must therefore strive to be free of the passions, bearing in mind that the ancient meaning of passion was anguish or suffering, in reaction to external events. The idea was to be free of suffering through apatheia (apathy: literally, "without passion") or peace of mind, being objective, or having clear judgment and equanimity in the face of life's highs and lows.
Following Socrates, the Stoics held that unhappiness and evil are the results of human ignorance of the divine reason in nature. Suicide was permissible for the wise person in circumstances that might prevent them from living a virtuous life. Suicide could also be justified if one fell victim to severe pain or disease, but otherwise suicide would usually be seen as a rejection of one's social duty.
Stoic philosophical and spiritual practices included logic, Socratic dialogue and self-dialogue, contemplation of death, and training attention to remain in the present moment (similar to mindfulness and some forms of meditation), and daily reflection on everyday problems and possible solutions with journaling.
"Say to yourself in the early morning: I shall today meet ungrateful, violent, treacherous, envious, uncharitable men. All of the 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"... Marcus Aurelius
Many parallels between Stoic spiritual exercises and modern cognitive behavioral therapy have been identified. Stoics commonly employ ‘The View from Above’, reflecting on society and otherness in guided visualization, aiming to gain a "bigger picture". "A fine reflection from Plato. One who would converse about human beings should look on all things earthly as though from some point far above, upon herds, armies, and agriculture, marriages and divorces, births and deaths, the clamor of law courts, deserted wastes, alien peoples of every kind, festivals, lamentations, and markets, this intermix of everything and ordered combination of opposites". Marcus Aurelius
A distinctive feature of Stoicism is its cosmopolitanism; all people are manifestations of the one universal spirit and should live in brotherly love and readily help one another. They held that external differences, such as rank and wealth, are of no importance in social relationships. 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."
Influences on Christianity: The apostle Paul met with Stoics during his stay in Athens, as reported in Acts 17:16–18. In his letters, Paul reflected heavily from his knowledge of Stoic philosophy, using Stoic terms and metaphors to assist his new Gentile converts in their understanding of Christianity. Early Christian writers employed some of the central philosophical concepts of Stoicism. Examples include the terms "logos", "virtue", "spirit", and "conscience". But the parallels go well beyond the sharing and 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, a sense of the innate depravity—or "persistent evil"—of humankind, and the futility and temporary nature of worldly possessions and attachments. Both encourage Ascesis (asceticism) with respect to the passions and inferior emotions, such as lust, and envy, so that the higher possibilities of one's humanity can be awakened and developed. Stoic writings such as Meditations by Marcus Aurelius have been highly regarded by many Christians throughout the centuries.
