A tragedy is the imitation of an action that is serious and also, as having magnitude, complete in itself . . . with incidents arousing pity and fear, wherewith to accomplish its catharsis of such emotions.
Metaphysics is universal and is exclusively concerned with primary substance. ... And here we will have the science to study that which is, both in its essence and in the properties which it has.
We are masters of our actions from the beginning up to the very end. But, in the case of our habits, we are only masters of their commencement - each particular little increase being as imperceptible as in the case of bodily infirmities. But yet our habits are voluntary, in that it was once in our power to adopt or not to adopt such or such a course of conduct.
