Vices are based off the desire for some good, but they could not be vices if they attained this good in a complete manner. But to desire any good is to desire it as a whole, and so vices are characterized by implicit contradiction between what is sought and what will be attained. What are the unique contradictions of the various vices?
Pride: in seeking ones own excellence, we end up in the dark “humility” of embarrassment over our past failures, unhappiness over what we can achieve, self-loathing over our own inability to follow things through, and the perpetual dissatisfaction feeling of being cheated out of all the things we feel are due to us.
Envy: In seeking that we should be a source of good things for others, we come to hate that others have any good of themselves.
Gluttony: The desire to preserve existence destroys the very existence that we sought to preserve.
Lust: The desire for the pleasure of sexual union leads to dissatisfaction with and alienation from others.
Wrath: The desire for justice – which requires harmonious life with others – turns into a desire to crush others and lord it over them.
Greed: The desire for self sufficiency becomes an imprisonment to the things we think can grant it.
Sloth: By seeking the smooth activity of life, we lose the very activity that constitutes life.
