I call him free who is led solely by reason.
Do not weep; do not wax indignant. Understand.
A good thing which prevents us from enjoying a greater good is in truth an evil.
The mind can only imagine anything, or remember what is past, while the body endures.
In so far as the mind sees things in their eternal aspect, it participates in eternity.
If you want the present to be different from the past, study the past.
