In inventing a model we may assume what we wish, but should avoid impossibilities.

Of actions some aim at what is necessary and useful, and some at what is honorable. And the preference given to one or the other class of actions must necessarily be like the preference given to one or other part of the soul and its actions over the other; there must be war for the sake of peace, business for the sake of leisure, things useful and necessary for the sake of things honorable.

The ridiculous is produced by any defect that is unattended by pain, or fatal consequences; thus, an ugly and deformed countenance does not fail to cause laughter, if it is not occasioned by pain.

A man is his own best friend; therefore he ought to love himself best.

No one praises happiness as one praises justice, but we call it a 'blessing,' deeming it something higher and more divine than things we praise.

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

Virtue also depends on ourselves. And so also does vice. For where we are free to act we are also free to refrain from acting, and where we are able to say No we are also able to say Yes; if therefore we are responsible for doing a thing when to do it right, we are also responsible for not doing it when not to do it is wrong, and if we are responsible for rightly not doing a thing, we are also responsible for wrongly doing it.
