Choice not chance determines your destiny [my family motto...credited to Aristotle]

We, on the other hand, must take for granted that the things that exist by nature are, either all or some of them, in motion.

There are three qualifications required in those who have to fill the highest offices, - (1) first of all, loyalty to the established constitution; (2) the greatest administrative capacity; (3) virtue and justice of the kind proper to each form of government.

For nature by the same cause, provided it remain in the same condition, always produces the same effect, so that either coming-to-be or passing-away will always result.

If a man of good natural disposition acquires Intelligence [as a whole], then he excels in conduct, and the disposition which previously only resembled Virtue, will now be Virtue in the true sense. Hence just as with the faculty of forming opinions [the calculative faculty] there are two qualities, Cleverness and Prudence, so also in the moral part of the soul there are two qualities, natural virtue and true Virtue; and true Virtue cannot exist without Prudence.

Virtue makes us aim at the right end, and practical wisdom makes us take the right means.

Happiness involves engagement in activities that promote one's highest potentials.
