What are the main points in Bacon's essay "Of Delay"?
Bacon's main points, couched in much Classical allusion,
it is sometimes like Sibylla’s offer; which at first, offereth the commodity at full, then consumeth part and part, and still holdeth up the price.
are that, when addressing approaching dangers, (1) it is imperative to wait though (2) equally imperative to not wait too long.
This is what he means by "it were better, to meet some dangers half way": waiting too long can overstay the moment and lead to as much harm as over-anticipating the moment to act. The two greatest attributes in facing danger are wisdom in counsel and planning and speed in acting once decided the time is right: "secrecy in the counsel, and celerity in the execution" (celerity: swiftness of movement).
