Ecclesiastes 1:14,15

I have seen all the works, &c. Diligently observed, and, in a great measure, understood them; and behold, all is vanity and vexation of spirit Not only unsatisfying, but also an affliction or breaking to a man's spirit. That which is crooked, &c. All our knowledge serves only to discover our miseries, but is utterly insufficient to remove them; it cannot rectify those disorders which are either in our own hearts and lives, or in the men and things of the world. That which is wanting In our knowledge, and in order to man's complete satisfaction and happiness; cannot be numbered Or, counted out to us from the treasures of human learning, but what is wanting will be so still; all our enjoyments here, when we have done our utmost to bring them to perfection, are still defective: and that which is wanting in our own knowledge is so much, that it cannot be numbered. The more we know, the more we see of our own ignorance.
