It is very good for a man to talk about what he does not understand; as long as he understands that he does not understand it. Agnosticism (which has, I am sorry to say, almost entirely disappeared from the modern world) is always an admirable thing, so long as it admits that the thing which it does not understand may be much superior to the mind which does not understand it. Thus if you say that the cosmos is incomprehensible, and really mean (as most moderns do) that it is not worth comprehending; then it would be much better for your Greek agnosticism if it were called by its Latin name of ignorance.
