We feel and know that we are eternal.

...The body is affected by the image of the thing, in the same way as if the thing were actually present.

In the mind there is no absolute or free will.

The proper study of a wise man is not how to die but how to live.

To comprehend an idea, a person must simultaneously accept it as true. Conscious analysis - which, depending on the idea, may occur almost immediately or with considerable effort - allows the mind to reject what it intially accepted as fact.

Only that thing is free which exists by the necessities of its own nature, and is determined in its actions by itself alone.

Love is nothing but joy accompanied with the idea of an eternal cause.
