A simple example of the Stoic categories in use is provided by Jacques Brunschwig:

. For the Stoics, reason meant using logic and understanding the processes of nature—the logos or universal reason, inherent in all things. The Greek word '' pathos'' was a wide-ranging term indicating an infliction one suffers. The Stoics used the word to discuss many common emotions such as anger, fear and excessive joy. A passion is a disturbing and misleading force in the mind which occurs because of a failure to reason correctly. For the Stoic Chrysippus, the passions are evaluative judgements. A person experiencing such an emotion has incorrectly valued an indifferent thing. A fault of judgement, some false notion of good or evil, lies at the root of each passion. Incorrect judgement as to a present good gives rise to delight, while lust is a wrong estimate about the future. Unreal imaginings of evil cause distress about the present, or fear for the future. The ideal Stoic would instead measure things at their real value, and see that the passions are not natural. To be free of the passions is to have a happiness which is self-contained. There would be nothing to fear—for unreason is the only evil; no cause for anger—for others cannot harm you.


Passions

The Stoics arranged the passions under four headings: distress, pleasure, fear and lust. One report of the Stoic definitions of these passions appears in the treatise ''On Passions'' by Pseudo-Andronicus (trans. Long & Sedley, pg. 411, modified): *Distress (lupē): Distress is an

but in reality bad. *Delight (hēdonē): Delight is an irrational swelling, or a fresh opinion that something good is present, at which people think it right to be elated. Two of these passions (distress and delight) refer to emotions currently present, and two of these (fear and lust) refer to emotions directed at the future. Thus there are just two states directed at the prospect of good and evil, but subdivided as to whether they are present or future: Numerous subdivisions of the same class were brought under the head of the separate passions: *Distress:

Instead the sage experiences good-feelings (''eupatheia'') which are clear-headed. These emotional impulses are not excessive, but nor are they diminished emotions. Instead they are the correct rational emotions. The Stoics listed the good-feelings under the headings of joy (''chara''), wish (''boulesis''), and caution (''eulabeia''). Thus if something is present which is a genuine good, then the wise person experiences an uplift in the soul—joy (''chara''). The Stoics also subdivided the good-feelings: *Joy: Enjoyment, Cheerfulness Good spirits *Wish: Good intent, Goodwill, Welcoming, Cherishing, Love *Caution:Moral shame, Reverence


Suicide

The Stoics accepted that suicide was permissible for the wise person in circumstances that might prevent them from living a virtuous life,Don E. Marietta, (1998), ''Introduction to ancient philosophy'', pp. 153–54. Sharpe such as if they fell victim to severe pain or disease, but otherwise suicide would usually be seen as a rejection of one's social duty.William Braxton Irvine, (2009), ''A guide to the good life: the ancient art of Stoic joy'', p. 200.

He regarded same sex relationships positively, and maintained that wise men should "have carnal knowledge no less and no more of a favorite than of a non-favorite, nor of a female than of a male." Zeno favored love over desire, clarifying that the ultimate goal of sexuality should be virtue and friendship. Among later stoics, Epictetus maintained homosexual and

Legacy


Neoplatonism

Plotinus criticized both Aristotle's Categories and those of the Stoics. His student Porphyry however defended Aristotle's scheme. He justified this by arguing that they be interpreted strictly as expressions, rather than as metaphysical realities. The approach can be justified, at least in part, by Aristotle's own words in ''The Categories.''
Boethius Anicius Manlius Severinus Boethius, commonly known as Boethius (; Latin: ''Boetius''; 480 – 524 AD), was a Roman senator, consul, ''magister officiorum'', historian, and philosopher of the Early Middle Ages. He was a central figure in the tr ...

Christianity

The Fathers of the Church regarded Stoicism as a "pagan philosophy";

nonetheless, early Christian writers employed some of the central philosophical concepts of Stoicism. Examples include the terms "logos", "

", "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'' 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 influence can also be seen in the works of

This subsequently became a common element in the socialization phase of many other approaches to CBT. The question of Stoicism's influence on modern psychotherapy, particularly REBT and CBT, was described in detail in ''The Philosophy of Cognitive–Behavioural Therapy'' by Donald Robertson. Several early 20th century psychotherapists were influenced by Stoicism, most notably the "rational persuasion" school founded by the Swiss neurologist and psychotherapist Paul DuBois, who drew heavily on Stoicism in his clinical work and encouraged his clients to study passages from
