You will learn why the Stoics held that your true city is not your nation but the whole rational cosmos, and what that claim demands of you.

Living according to nature
You will learn what the Stoics meant by nature as a standard, and why it points to reason and community rather than to instinct or simplicity.
-
Impressions (phantasiai)
You will learn why the Stoics thought the real battle happens before you react, in the instant something first strikes your mind.

You will learn why Epictetus treats desire and aversion, not pleasure and pain, as the hinge on which a good life turns.

Assent is the mind's power to say yes or no to an impression, and the Stoics treat training it as the whole work of philosophy.

You will learn why the Stoics thought rational beings are built for each other, and why acting for the common good is not self-sacrifice but self-interest correctly understood.

You will learn why Stoic tranquility is not a feeling you chase but a state of mind you build by returning to a few fundamental judgments.
