What Is This?
Examining impressions is the practice of pausing, in the moment, between something happening and your reaction to it, to check whether your first read of the event is accurate. It’s built on a specific Stoic distinction (see Impressions and Assent): an impression is the automatic first read something makes on you; a judgment is what you add to it, and that part is up to you. This practice is the discipline of catching that gap while it’s still open, instead of after you’ve already reacted.
Why Practice It?
Most of what people call “overreacting” isn’t a reaction to what happened, it’s a reaction to an unexamined assumption about what happened. A short reply from a friend gets read as “they’re annoyed with me,” when it might just mean they were in a meeting. The event was two words in a text message. Everything else was added. Examining impressions catches that addition before it becomes a full-blown reaction you then have to walk back.
Stoic Roots
Primary source
Seek at once, therefore, to be able to say to every unpleasing semblance, 'You are but a semblance and by no means the real thing.' And then examine it by those rules which you have; and first and chiefly by this: whether it concerns the things which are within our own power or those which are not; and if it concerns anything beyond our power, be prepared to say that it is nothing to you.
This is arguably the single most central practice in surviving Stoic teaching. Epictetus returns to it constantly across the Discourses and the Enchiridion: the discipline of testing an impression before assenting to it, rather than treating your first read of events as automatically true. The scholar Pierre Hadot describes this kind of ongoing attention (prosochē) as the foundational Stoic exercise everything else builds on, not one technique among many.
How to Do It
Notice the pause between something happening and your reaction to it, even if it's less than a second.
Name what actually happened, in plain terms, separate from your interpretation of it.
Ask: is this within my control, or not?
Ask: what am I assuming here that isn't actually confirmed?
Decide your response after that check, not before it.
When to Use It
The moment you notice a strong reaction starting, irritation, hurt, panic, defensiveness. It’s a real-time practice rather than a scheduled one, which makes it the hardest of the seven to build as a habit; it helps to pick one or two recurring triggers (a specific person, a specific kind of message) and practice on those first.
Example
A coworker doesn’t reply to your message for a full day. The impression arrives instantly: “they’re ignoring me on purpose.” Examining it: what actually happened is that you sent a message and haven’t received a reply yet. Whether they’re ignoring you is not confirmed, it’s an assumption filled in around a gap in information. What’s up to you is sending a polite follow-up if it’s genuinely time-sensitive; what isn’t up to you is their reason for the delay.
Common mistake: treating this as “don’t trust your feelings” or suppressing the initial impression itself. Epictetus isn’t asking you to feel nothing when something happens, he’s asking you to check the judgment you’ve layered on top before you act on it. The impression can arrive; assent to it is the part you control.
