Adiaphora (Glossary Entry)

Etymology and Origin: The Greek word adiaphora (ἀδιάφορα) literally means "not different" or "indistinguishable." In Stoic ethics, it refers to things that are not intrinsically good or bad—they are morally neutral. The concept was developed by the early Stoics, particularly Zeno of Citium and Chrysippus, as a way of clarifying what truly matters for human flourishing (eudaimonia).

Core Distinction:

• Preferred Indifferents (proēgmena): Things that have positive value in accordance with nature. Health, strength, wealth, reputation, and life itself are preferred because they are naturally conducive to living well. The sage will rationally choose them when possible.
• Dispreferred Indifferents (apoproēgmena): Things that have negative value in accordance with nature. Disease, weakness, poverty, obscurity, and death are dispreferred because they naturally hinder living well. The sage will rationally avoid them when possible.

A common misunderstanding is that 'indifferent' means 'unimportant.' This is not the Stoic view. The Stoics recognized that health and wealth matter in the ordinary course of life. What they denied is that these things have any bearing on your moral character. A virtuous person can be healthy or sick, rich or poor, famous or unknown—their virtue remains intact. The indifference is not about the value of the thing itself; it is about the thing's irrelevance to the only thing that ultimately matters: the quality of your choices.

Relation to the Dichotomy of Control: Adiaphora belong to the category of things not up to us. Since we cannot fully control whether we are healthy, wealthy, or respected, these things cannot be the foundation of our happiness. The dichotomy teaches us to pursue preferred indifferents with moderation and to accept dispreferred indifferents without distress, always keeping in mind that our true good lies in the virtuous use of our prohairesis.

Criticisms: The concept of adiaphora has been criticized for being too intellectualized—it seems to deny the natural human attachment to life, health, and loved ones. Critics argue that it is impossible to truly regard the death of a child as 'indifferent.' Stoics respond that the doctrine does not forbid grief or natural attachment; it only insists that these attachments should not become the basis of our moral identity. The sage can love deeply while recognizing that the beloved is not within their ultimate control.

Influence: The concept of adiaphora influenced later Christian thinkers like Augustine, who distinguished between things to be enjoyed (God) and things to be used (everything else). It also shaped the development of modern ethical theories that distinguish between intrinsic and instrumental values. In contemporary Stoic practice, the concept is used to help people prioritize their concerns and detach from outcomes they cannot control.
