Prosoche — the practice of attention

Maintain constant, vigilant attention to your own thoughts, judgments, and impulses as they arise.

Why it works

Hadot identifies prosoche (attention to oneself) as the foundational practice for Stoics — especially Epictetus and Marcus Aurelius. The mechanism is metacognitive: attending to your own thoughts as they arise gives you the moment of choice between impression and response that Epictetus called the space of freedom. Without this attention, impressions automatically become endorsements; with it, the automatic becomes deliberate.

How to do it

1. Set the intention at the start of the day: "Today I will notice my thoughts and judgments as they arise, before endorsing them."
2. When a strong reaction arises (anger, anxiety, desire), pause and name it: "This is an impression. I have not yet decided whether it is true."
3. Practice the gap between impression and response — even for three seconds — as often as you can throughout the day.
4. At day’s end, note two moments where attention succeeded and one where it failed.

Evidence

Metacognitive awareness is the mechanism of change in mindfulness-based interventions, which have substantial evidence for reducing rumination and emotional reactivity; Hadot’s prosoche is the ancient version of the same practice. (clinical)

MBCT evidence supports mindful attention in clinical contexts; prosoche as Hadot describes it is a broader philosophical practice encompassing vigilance about all impressions, not only depressive ones.

Common mistake

Treating attention as something to do only in formal meditation, rather than as a continuous practice throughout the day — which is exactly what Hadot says the Stoics meant by it.
