From Margaret R. Graver's Stoicism and Emotion:
"As a normative response can hardly be dependent on any false belief, the evaluations that give rise to eupatheiai will necessarily be true. The objects at which they are directed must therefore be such objects as the person of perfect understanding can consider to be goods or evils. They may be bound up with externals in that actions and decisions have to be about something, but the external aspects of action would not be the real objects of the feeling. The real objects must be those integral goods and evils which are, as Seneca says, 'real and the mind's own'."
