Of Discourse by Francis Bacon

Of Discourse by Francis Bacon In her book Francis Bacon: Discovery and the Art of Discourse (1974), Lisa Jardine argues that Bacons Essays fall squarely under the heading of presentation or method of discourse. They are didactic, in Agricolas sense of presenting knowledge to someone in a form in which it may be believed and assimilated. . . . Basically these essays communicate precepts for the guidance of personal conduct in public affairs, based on Bacons own political experience. In the essay titled Of Discourse, Bacon explains how a person can lead the dance without appearing to dominate a conversation. You may find it worthwhile to compare Bacons aphoristic observations with the lengthier reflections offered by Jonathan Swift in Hints Toward an Essay on Conversation and by Samuel Johnson in Conversation. Of Discourse Some in their discourse desire rather commendation of wit, in being able to hold all arguments, than of judgment, in discerning what is true; as if it were a praise to know what might be said, and not what should be thought. Some have certain common-places and themes, wherein they are good, and want variety; which kind of poverty is for the most part tedious, and, when it is once perceived, ridiculous. The honourablest part of talk is to give the occasion; and again to moderate and pass to somewhat else, for then a man leads the dance. It is good in discourse, and speech of conversation, to vary and intermingle speech of the present occasion with arguments, tales with reasons, asking of questions with telling of opinions, and jest with earnest: for it is a dull thing to tire, and as we say now, to jade any thing too far. As for jest, there be certain things which ought to be privileged from it; namely, religion, matters of state, great persons, any mans present business of importance , any case that deserveth pity; yet there be some that think their wits have been asleep, except they dart out somewhat that is piquant, and to the quick; that is a vein which would be bridled; Parce, puer, stimulis, et fortius utere loris.* And, generally, men ought to find the difference between saltness and bitterness. Certainly, he that hath a satirical vein, as he maketh others afraid of his wit, so he had need be afraid of others memory. He that questioneth much, shall learn much, and content much; but especially if he apply his questions to the skill of the persons whom he asketh; for he shall give them occasion to please themselves in speaking, and himself shall continually gather knowledge; but let his questions not be troublesome, for that is fit for a poser; and let him be sure to leave other men their turns to speak: nay, if there be any that would reign and take up all the time, let him find means to take them oft, and to bring others on, as musicians use to do with those that dance too long galliards. If you dissemble sometimes your knowledge of that you are thought to know, you shall be thought, another time, to know that you know not. Speech of a mans self ought to be seldom, and well chosen. I knew one w as want to say in scorn, He must needs be a wise man, he speaks so much of himself: and there is but one case wherein a man may commend himself with good grace, and that is in commending virtue in another, especially if it be such a virtue whereunto himself pretendeth. Speech of touch towards others should be sparingly used; for discourse ought to be as a field, without coming home to any man. I knew two noblemen, of the west part of England, whereof the one was given to scoff, but kept ever royal cheer in his house; the other would ask of those that had been at the others table, Tell truly, was there never a flout or dry blow given? To which the guest would answer, Such and such a thing passed. The lord would say, I thought he would mar a good dinner. Discretion of speech is more than eloquence; and to speak agreeable to him with whom we deal, is more than to speak in good words, or in good order. A good continued speech, without a good speech of interlocution, shows slowness; and a good reply, or second speech, without a good settled speech, showeth shallowness and weakness. As we see in beasts, that those that are weakest in the course, are yet nimblest in the turn: as it is betwixt the greyhound and the hare. To use too many circumstances, ere one come to the matter, is wearisome; to use none at all, is blunt. Â   (1625) * Spare the whip, boy, and hold tighter the reins (Ovid, Metamorphoses).

Where to Buy Copper Sulfate Pentahydrate

Where to Buy Copper Sulfate Pentahydrate Copper sulfate pentahydrate (also known as copper sulphate pentahydrate or simply copper sulfate or copper sulphate) is the chemical used to grow bright blue copper sulfate crystals. Its easy to find online, but there are shipping restrictions to some locations, plus the weight of the chemical typically makes shipping comparable to the price of the chemical. Fortunately, copper sulfate is a useful chemical that you may be able to find in a store... if you know where to look. Stores That Sell Copper Sulfate I found copper sulfate at Home Depot as Zep Root Killer, which is labeled as copper sulfate pentahydrate and is sold with septic tank and drain cleaning chemicals (not with other garden root killers or with other plumbing chemicals). This product contains solid granules of copper sulfate. Its very easy to work with. If you wish to use it to grow crystals, dissolve it in hot water and then use a coffee filter to remove large impurities. Less commonly, you can find copper sulfate granules sold as an algicide for ponds. Ask for an algicide solid or powder and make certain the product is labeled as copper sulfate or copper sulfate pentahydrate. Its fairly easy to find copper sulfate solutions, but youll probably need to evaporate off some water to get the concentration you need.
