I have with great Pains and Industry made my Observations from time to time upon these Sages; and having now all Materials ready, am compiling a Treatise, wherein I shall set forth the Rise and Progress of this famous Sect, together with their Maxims, Austerities, Manner of living, &c. Having prevailed with a Friend who designs shortly to publish a new Edition of _Diogenes Laertius_, to add this Treatise of mine by way of Supplement; I shall now, to let the World see what may be expected from me (first begging Mr. SPECTATOR'S Leave that the World may see it) briefly touch upon some of my chief Observations, and then subscribe my self your humble Servant. In the first Place I shall give you two or three of their Maxims: The fundamental one, upon which their whole System is built, is this, viz. That Time being an implacable Enemy to and Destroyer of all things, ought to be paid in his own Coin, and be destroyed and murdered without Mercy by all the Ways that can be invented. Another favourite Saying of theirs is, That Business was designed only for Knaves, and Study for Blockheads. A third seems to be a ludicrous one, but has a great Effect upon their Lives; and is this, That the Devil is at Home. Now for their Manner of Living: And here I have a large Field to expatiate in; but I shall reserve Particulars for my intended Discourse, and now only mention one or two of their principal Exercises. The elder Proficients employ themselves in inspecting _mores hominum multorum_, in getting acquainted with all the Signs and Windows in the Town. Some are arrived at so great Knowledge, that they can tell every time any Butcher kills a Calf, every time any old Woman's Cat is in the Straw; and a thousand other Matters as important. One ancient Philosopher contemplates two or three Hours every Day over a Sun-Dial; and is true to the Dial, ... As the Dial to the Sun, Although it be not shone upon. [2] Our younger Students are content to carry their Speculations as yet no farther than Bowling-greens, Billiard-Tables, and such like Places. This may serve for a Sketch of my Design; in which I hope I shall have your Encouragement. I am, SIR, Yours. [3] I must be so just as to observe I have formerly seen of this Sect at our other University; tho' not distinguished by the Appellation which the learned Historian, my Correspondent, reports they bear at _Cambridge_. They were ever looked upon as a People that impaired themselves more by their strict Application to the Rules of their Order, than any other Students whatever. Others seldom hurt themselves any further than to gain weak Eyes and sometimes Head-Aches; but these Philosophers are seized all over with a general Inability, Indolence, and Weariness, and a certain Impatience of the Place they are in, with an Heaviness in removing to another.
