Quisquis ubique habitat, Maxime, nusquam habitat.
[“He who lives everywhere, lives nowhere.” — Martial, vii]
General ignorance is a bad thing, perhaps the worst thing. Let us never accept our ignorance placidly. Just as life is greater than death — infinitely greater — so too is knowledge greater than ignorance. We should strive for knowledge as we strive for life, for both types grow toward the same source.
But I want to argue that specific ignorance is a good thing. What do I mean by “specific ignorance”? Specific ignorance is not mere absence but absence of something definite. The form of general ignorance is “I don’t know anything,” whereas specific ignorance is “I don’t know this thing”. Such ignorance is essentially dynamic and oriented toward the reality of the specific. Perhaps the first rule of good teaching is to transform a general ignorance into a specific ignorance, so that the striving that ought to accompany ignorance can flower into actuality. Here are a few leftover thoughts to get you thinking:
1. The vehicle of specific ignorance is the questionable opinion, not the blank page.
2. Try replacing periods with question marks.
3. There is no consummation without a prior animation.
4. Real knowledge is the fruit of specific ignorance; no plant, no fruit.

Ignorance is bliss?
I suppose that general ignorance could be blissful in the same way that numbness may be. But I think it is a bad deal to purchase bliss in exchange for life, even with all its anxieties and pains. Specific ignorance is not at all blissful.
