On final goal.
In order to live a good life, we should live according to experience of the things which happen by nature. The final goal is to obtain a practical knowledge and become an expert in selecting a thing in accordance with nature.
On emotions.
Passion is a bad judgement about something. It is an excessive motion of the soul.
On Fate and Freedom.
