Benjamin Franklin on Philosophy

":Would you persuade, speak of Interest, not of Reason."

"If you would keep your Secret from an enemy, tell it not to a friend.Up, Sluggard, and waste not life; in the grave will be sleeping enough."

"Make a small Cross of two light Strips of Cedar, the Arms so long as to reach to the four Corners of a large thin Silk Handkerchief when extended; tie the Corners of the Handkerchief to the Extremities of the Cross, so you have the Body of a Kite; which being properly accommodated with a Tail, Loop and String, will rise in the Air, like those made of Paper; but this being of Silk is fitter to bear the Wet and Wind of a Thunder Gust without tearing. To the Top of the upright Stick of the Cross is to be fixed a very sharp pointed Wire, rising a Foot or more above the Wood. To the End of the Twine, next the Hand, is to be tied a silk Ribbon, and where the Twine and the silk join, a Key may be fastened. This Kite is to be raised when a Thunder Gust appears to be coming on, and the Person who holds the String must stand within a Door, or Window, or under some Cover, so that the Silk Ribbon may not be wet; and Care must be taken that the Twine does not touch the Frame of the Door or Window. As soon as any of the Thunder Clouds come over the Kite, the pointed Wire will draw the Electric Fire from them, and the Kite, with all the Twine, will be electrified, and the loose Filaments of the Twine will stand out every Way, and be attracted by an approaching Finger. And when the Rain has wet the Kite and Twine, so that it can conduct the Electric Fire freely, you will find it stream out plentifully from the Key on the Approach of your Knuckle. At this Key the Phial may be charg'd; and from Electric Fire thus obtain'd, Spirits may be kindled, and all the other Electric Experiments be perform'd, which are usually done by the Help of a rubbed Glass Globe or Tube; and thereby the Sameness of the Electric Matter with that of Lightning compleatly demonstrated."

"Whilst the last members were signing it Doctor Franklin looking towards the President's Chair, at the back of which a rising sun happened to be painted, observed to a few members near him, that Painters had found it difficult to distinguish in their art a rising from a setting sun. "I have," said he, "often and often in the course of the Session, and the vicissitudes of my hopes and fears as to its issue, looked at that behind the President without being able to tell whether it was rising or setting: But now at length I have the happiness to know that it is a rising and not a setting Sun."

"[T]he waters moved away from the North American Coast towards the coasts of Spain and Africa, whence they get again into the Power of the Trade Winds, and continue the Circulation. ...so long and so strong a Current as that of the Gulph Stream, thro' all the Latitudes of variable Winds, can only be accounted for, by its having a considerable Descent, and moving from Parts where the Water is higher, to Parts where it is lower."

"[Referring to private hospital funding alone:] That won't work, it will never be enough, good health care costs a lot of money, remembering 'the distant parts of this province' in which 'assistance cannot be procured, but at an expense that neither [the sick-poor] nor their townships can afford.' ... '[This] seems essential to the true spirit of Christianity, and should be extended to all in general, whether deserving or undeserving, as far as our power reaches.'"

"Mankind naturally and generally love to be flatter'd: Whatever sooths our Pride, and tends to exalt our Species above the rest of the Creation, we are pleas'd with and easily believe, when ungrateful Truths shall be with the utmost Indignation rejected. "What! bring ourselves down to an Equality with the Beasts of the Field! with the meanest part of the Creation! 'Tis insufferable!" But, (to use a Piece of common Sense) our Geese are but Geese tho' we may think 'em Swans; and Truth will be Truth tho' it sometimes prove mortifying and distasteful."

"These Thoughts, my dear Friend, are many of them crude and hasty, and if I were merely ambitious of acquiring some Reputation in Philosophy, I ought to keep them by me, ’till corrected and improved by Time and farther Experience. But since even short Hints, and imperfect Experiments in any new Branch of Science, being communicated, have oftentimes a good Effect, in exciting the attention of the Ingenious to the Subject, and so becoming the Occasion of more exact disquisitions (as I before observed) and more compleat Discoveries, you are at Liberty to communicate this Paper to whom you please; it being of more Importance that Knowledge should increase, than that your Friend should be thought an accurate Philosopher."
