“Knowledge and timber shouldn't be much used, till they are seasoned.”

For the vulpine sharpness, which considers itself to be knowledge, and "detects" in that fashion, is far mistaken. Dupes indeed are many: but, of all dupes, there is none so fatally situated as he who lives in undue terror of being duped.

VI. 146–149 (tr. R. Lattimore); Glaucus to Diomed.
Alexander Pope's translation:
: Like leaves on trees the race of man is found,
Now green in youth, now withering on the ground:
Another race the following spring supplies,
They fall successive, and successive rise:
So generations in their course decay;
So flourish these, when those are past away.

Context: I read now and then in the papers that some eminent scientist had made a great discovery. He reads a paper before some Academy of Science, and there are leading articles on it, and his photograph adorns the magazines. That kind of man is not the danger. He is a bit of the machine, a party to the compact. It is the men who stand outside it that are to be reckoned with, the artists in discovery who will never use their knowledge till they can use it with full effect.

Context: No race can prosper till it learns that there is as much dignity in tilling a field as in writing a poem. It is at the bottom of life we must begin, and not at the top.

Context: I do not understand your custom in this, but we do not intend to fight until all of us are dead. We desire very much that none of us be dead. And we will fight till all of you are dead only if it is absolutely necessary.

Context: One cannot attain divine knowledge till one gets rid of pride. Water does not stay on the top of a mound; but into low land it flows in torrents from all sides.
