Right Speech
This week you are studying Right Speech, the Stoic idea that how you speak is a direct expression of your character and your reason. The Stoics did not have one single Greek term for this, but they rooted it in logos, the word for reason or rational discourse, the same principle they believed governs the universe and ought to govern your mouth. Right Speech means speaking only what is true, useful, measured, and fitting to the moment, and staying quiet when none of those conditions are met. By the end of this week you will not just understand the idea; you will have a set of habits you can actually use.
Passage
However, I have this further reason for frightening you away from the latter malady, namely, that you could only be successful in practising this style by losing your sense of modesty; you would have to rub all shame from your countenance, and refuse to hear yourself speak. For that heedless flow will carry with it many expressions which you would wish to criticize.
— Seneca, Letters 40.13
Reflection
Seneca's warning today is about a specific trap inside rapid, unguarded speech: you say things you would immediately want to take back, and doing it repeatedly costs you something important. You lose your sense of shame, your own honest self-assessment. The Stoics valued shame not as guilt but as a healthy signal that your actions have fallen short of your own standards. When you speak carelessly and often enough, that signal goes quiet. Right Speech requires a kind of inner listener: someone in you who is actually paying attention to what is being said. Today's passage asks whether that inner listener is still awake.

Is there a mode of speaking, venting, joking, arguing, explaining, where you notice afterward that you said more than you meant, or things you did not quite believe, and if so, what seems to switch that inner listener off?
Practice
Inner Listener Check
Choose one conversation today to observe as if you were a third party. Afterward, within a few minutes, write two sentences: one thing you said that you stand behind completely, and one thing you said that you would revise if you could. No judgment, just honest noticing. The goal is to keep that inner listener alert.
