Natural abilities are like natural plants, that need pruning by study; and studies themselves do give forth directions too much at large, except they be bounded in by experience.
...those experiments be not only esteemed which have an immediate and present use, but those principally which are of most universal consequence for invention of other experiments, and those which give more light to the invention of causes; for the invention of the mariner's needle, which giveth the direction, is of no less benefit for navigation than the invention of the sails, which give the motion.

But the idols of the Market Place are the most troublesome of all: idols which have crept into the understanding through their alliances with words and names.

Whenever an understanding of greater acuteness or more diligent observation would alter those lines to suit the true distinctions of nature, words complain.
But this is that which will dignify and exalt knowledge: if contemplation and action be more nearly and straitly conjoined and united together than they have been: a conjunction like unto that of the highest planets, Saturn, the planet of rest and contemplation, and Jupiter, the planet of civil society and action.
