Acta non verba: reading as action, and testing every impression

Executive overview

Saying you want to improve is not the same as improving. The Stoic principle acta non verba — deeds, not words — demands a first concrete step: getting and reading the books on the thing you claim to care about.

Reading is not transformation, but it is the first real act of commitment.

The second teaching, from Epictetus, goes deeper: even after you act, you must test what you find. Just as an assayer tests ore to distinguish gold from worthless rock, every perception and impression must be examined before you trust it.

Deeds, not words

• Most people claim they want change but skip the bare minimum — reading one book on the subject
• Ramit Sethi's observation: people with financial problems often haven't read a single book about money
• Reading is an action; it signals a real commitment to your values
• The goal is not to read once and be transformed, but to return to the material daily as a practice

Testing impressions with Epictetus

• Epictetus uses the verb "to assay" 10 times in Discourses — the act of testing perceptions like a metals assayer tests ore
• A skilled merchant can detect a counterfeit coin by sound; a musician detects a sour note — train yourself to detect false impressions the same way
• Cognitive biases, upbringing, and misleading appearances all distort first-glance perception
• The practice: assume everything in front of you is counterfeit until proven otherwise
• Slow down, pause, and verify — see what is actually there, not what others want you to see
