I was convinced despair was one of the seven, but the internet, on the whole, disagrees. That’ll teach me to break my rule here against Wikipedia. We can’t in any case readily inhabit the outlook of a truly religious age, with only God’s shadow left to us. There is a difference between despair and depression, for example; but what to make of it is up for grabs. The latter term undermines the attitude by casting it as a sickness — indeed, an affect rather than an attitude. My topic then (whatever Aquinas would have thought) is a considered view of the world, not a mere feeling about it, and how this might be morally wrong, in much the same way that I hold stupidity to be a moral failing, not sustainable as a concept except on those terms, that is, as being a choice.
To see this moral dimension, it may help to consider that an aspect of despair is misanthropy. If we abandon faith in human goodness, we are actually breaking faith with our more hopeful fellow men. The difficulty here is that what is supposed to save us from such despair is faith in God, who alone possesses the transcendent goodness to raise us up out of the mire. That thought is not enough to conjure the absent deity into existence.
Contemplating the world, from its most intimate manifestation in the life shared in common with those dear to us to its mendacious Zeitgeist, the grand stage of war, pestilence and tyranny — in microcosm and macrocosm — I see no light. And I see that as a personal failing, though I can do nothing for it. If that seems unreasonably harsh, it may help to recast the failure as a collective one, since macrocosm and microcosm are of a piece.
