Measure, time and number are nothing but modes of thought or rather of imagination.

Desire is the very essence of man

Men will find that they can ... avoid far more easily the perils which beset them on all sides by united action.

In proportion as we endeavor to live according to the guidance of reason, shall we strive as much as possible to depend less on hope, to liberate ourselves from fear, to rule fortune, and to direct our actions by the sure counsels of reason.

If men were born free, they would, so long as they remained free, form no conception of good and evil.

Everyone endeavors as much as possible to make others love what he loves, and to hate what he hates... This effort to make everyone approve what we love or hate is in truth ambition, and so we see that each person by nature desires that other persons should live according to his way of thinking.

The highest endeavor of the mind, and the highest virtue, it to understand things by intuition.
