The Core Dogmas of Stoicism
The core dogmas of Stoicism (Keith Seddon, "Stoics," message 2928; cf. Pierre Hadot, The Inner Citadel: The Meditations of Marcus Aurelius, pp. 36-43 and Bruce MacLennan, Notes on Marcus Aurelius IV, B) are:
(1) Our rationality is a fragment of God's (one consequence of which is that we are obliged to perfect it).
(2) The only good is virtue and action motivated by virtue; the only evil is vice and action motivated by vice.
(3) The only things entirely within our own power (all
things being equal) are our intentions, judgements, desires and aversions.
