Man’s soul dishonors itself, when it does all it can to become an growth, a tumor as it were on the Universe. To worry about any particular event is to revolt against the general law of Nature, which comprehends the order of all events whatsoever.

Again it is dishonor for the soul when it has aversion to any man, and opposes him with intention to hurt him, as wrathful men do.

Thirdly, the soul affronts itself when conquered by pleasure or pain;

Fourthly, when it does or says anything hypocritically, feignedly or falsely;

Fifthly, when it does not direct to some proper end all its desires and actions, but exerts them inconsiderately and without understanding. For, even the smallest things should be referred to the end, and the end of rational beings is to follow the order and law of the venerable state and polity which comprehends them all.
