passions in different men may conflict, but men who live in obedience to reason will agree together.

Context

“But his conception of what a wise man will choose as the goal of his self-seeking is different from that of the ordinary egoist: “The mind’s highest good is the knowledge of God, and the mind’s highest virtue is to know God.” Emotions are called “passions” when they spring from inadequate ideas; passions in different men may conflict, but men who live in obedience to reason will agree together. Pleasure in itself is good, but hope and fear are bad, and so are humility and repentance: “he who repents of an action is doubly wretched or infirm.” Spinoza regards time as unreal, and therefore all emotions which have to do essentially with an event as future or as past are contrary to reason.” source
