It is not good for us to seek deep Knowledge : for deep things are unknowable. See how Simplicity is better than Cleverness.

But it is not right for us to look at all things minutely, but rather simply—not that our Knowledge is to be Ignorance; for even in the case of something which a man does not do cleverly, if he does the thing with clever discrimination then his lack of Cleverness is Cleverness. And if, by his Knowledge he becomes an ignorant man so that he ignores those things which he cannot know, even his Ignorance is great Knowledge. For because he knows that they are not known, his Knowledge cannot be Ignorance. For he knows well whatever he knows. But the mind in which many doubts spring up, destroying one another, cannot do anything readily. For thoughts, vanquishing and vanquished, are produced by it, and the waves which from all sides beat upon it, fix it in doubt and inaction. [Ov. p. 31, l. 12.] But it is an advantage that the scale of simplicity should outweigh in us the scale of wrangling-logic. For how many times, in consequence of the clever and subtle thoughts which we have concerning a matter, that very matter is delayed so as not to be accomplished! And consider that in the case of those matters which keep the world alive, Simplicity accomplishes them without many thoughts. For these matters succeed when a single thought controls them, and they stand still when many thoughts rush in. For there is only a single thought in Husbandry, that is (the thought) that in a simple manner it should scatter the seed in the earth. But if other thoughts occurred to it so that it pondered and reasoned as to whether the seed was sprouting or not, or whether the earth would fail to produce it, or would restore it again, then Husbandry could not sow. For morbid thoughts spring up against a single [ix] sound thought, and weaken it. And because a thing is weakened, it cannot work like a sound thing. For the soundness of a [Ov. p. 32.] thought like the soundness of a body performs everything. And the husbandman who cannot plough with one ox cannot plough with two thoughts. Just as it is useful to plough with two oxen, so it is right to employ one healthy thought.
