Error, sight, and the way of ignorance.
From The Way of Ignorance and Other Essays:
There are kinds and degrees of ignorance that are remediable, of course, and we have no excuse for not learning all we can. Within limits, we can learn and think; we can read, hear, and see; we can remember. We don’t have to live in a world defined by professional and political gibberish.
But… our ignorance ultimately is irremediable… Do what we will, we are never going to be free of mortality, partiality, fallibility, and error. The extent of our knowledge will always be, at the same time, the measure of the extent of our ignorance.
Because ignorance is thus a part of our creaturely definition, we need an appropriate way: a way of ignorance, which is the way of neighborly love, kindness, caution, care, appropriate scale, thrift, good work, right livelihood…
The way of ignorance, therefore, is to be careful, to know the limits and the efficacy of our knowledge. It is to be humble and to work on an appropriate scale.
