Ask Stoics source guide · Stoic Distinctions
Right Action and Final Outcome
Stoic philosophy draws a clear line between what is within our control and what is not. This distinction is crucial for understanding how to live a virtuous life. We are responsible for our intentions, efforts, and the actions we choose, but the ultimate results often lie beyond our direct influence. By focusing on right action, we align ourselves with reason and duty, regardless of the external outcome.
On this page you will get a clear explanation, a way to examine the idea, exact evidence from public-domain Stoic texts, and links for continuing the study.
The Nature of Duty
Duty, or appropriate action, is something that can be rightly begun. It is an action for which an adequate reason can be provided, distinguishing it from absolute duty, which is considered right in itself.
The wise person is not inactive; when they act, they judge that action to be their duty. This judgment, being free from error, places duty among those things that are neither good nor bad in themselves.

Mean Duty vs. Absolute Duty
There are two classifications of duty: mean duty and absolute duty. Mean duty is an action for which a reasonable justification can be given, such as restoring a deposit.
Absolute duty, which the Greeks call 'katorthoma,' is defined as whatever is right. This implies a higher standard of action, inherently aligned with virtue.
Sources: Cicero, On Duties 1.8; Cicero, On Ends 3.18
The Role of Selection
Virtue should not be understood as merely a selection from suitable and natural beginnings. If virtue were only about selection, it would imply that the chief good needs something beyond itself.
All things to be taken, chosen, or desired should exist within the chief good itself. One who has attained the chief good should not require anything more from external choices.
Sources: Cicero, On Ends 4.17
Actions and Their Justification
An action is considered a duty if an adequate reason can be provided for its performance. This means that the rationale behind the action is what makes it a duty.
For example, if restoring a justly deposited item is a right action, then the act of restoring it is a duty. The 'justly' part makes the duty rightly performed.
Sources: Cicero, On Duties 1.8; Cicero, On Ends 3.18
Focus on the Process, Not Just the Result
The focus is on the rightness of the action itself, not solely on the final outcome. The wise person acts based on what they judge to be their duty, and this judgment is never mistaken.
This perspective encourages individuals to concentrate on their conduct and preparation, understanding that the ultimate result is often outside their complete control.
Sources: Cicero, On Ends 3.18
The Independence of Virtue
The chief good, which is virtue, should be self-sufficient. It should not depend on external selections or outcomes to be complete or to acquire something more.
This contrasts with philosophies that base the chief good on external factors like pleasure, where actions are guided by what they ought to do to achieve that pleasure.

“And yet there is still another classification of duties: we distinguish between mean duty, so called, and absolute duty. Absolute duty we may, I presume, call right, for the Greeks call it kato/rqwma, while the ordinary duty they call kaqh=kon.”
“For since we see that there is something which we pronounce to have been rightly done (for that is duty when accomplished), there must also be something which is rightly begun: as, if to restore what has been justly deposited belongs to the class of right actions, then it must be classed among the duties to restore a deposit; and the addition of the word “justly” makes the duty to be rightly performed: but the mere fact of restoring is classed as…”
“For virtue ought not to have been stated to consist in selection, so that that very thing which was itself the chief good, was to acquire something besides itself; for all things which are to be taken, or chosen, or desired, ought to exist in the chief good, so that he who has attained that may want nothing more.”
Frequently asked questions
What is the difference between mean duty and absolute duty?
Mean duty is an action for which an adequate reason can be given, like restoring a deposit. Absolute duty, or 'katorthoma,' is defined as whatever is inherently right, aligning with virtue itself.
Sources: Cicero, On Duties 1.8; Cicero, On Ends 3.18
Why is the wise person never deceived in judging duty?
The wise person's judgment of duty is based on reason and what is appropriate, not on external outcomes. This internal alignment means their judgment of what constitutes duty is sound and consistent.
Sources: Cicero, On Ends 3.18
How does Stoicism view the relationship between virtue and selection?
Stoicism holds that virtue should not be merely a selection from external options. Virtue itself is the chief good, and it should be self-sufficient, not needing to acquire anything beyond itself through selection.
Sources: Cicero, On Ends 4.17
What makes an action a 'duty' according to Stoic thought?
An action is a duty if an adequate reason can be provided for its performance. The justification and appropriateness of the action itself, rather than its final result, define it as a duty.
