Abstract
In this paper, I will deal with the Chrysippean theory of co-fated events. In order to do so, in the first part, I will present Chysippus’ simile of the dog tied to a car and its fatalistic implications. In the second part, I will present the ancient critique known as lazy argument. In the end, I will propose a new interpretation of Chrysippus’s distinction of fated and co-fated events in order to re-examine how he answered this critique. This Chrysippean theory shows how relevant philosophical understanding of fate is in order to avoid fatalism, and safeguard the value of our personal efforts and practical thought.
