S. Austin Allibone, comp. Prose Quotations from Socrates to Macaulay. 1880.
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.
The first and the simplest emotion which we discover in the human mind is curiosity. By curiosity I mean whatever desire we have for, or whatever pleasure we take in, novelty. We see children perpetually running from place to place, to hunt out something new; they catch with great eagerness, and with very little choice, at whatever comes before them; their attention is engaged by everything, because everything has, in that stage of life, the charm of novelty to recommend it. But, as those things which engage us merely by their novelty cannot attach us for any length of time, curiosity is the most superficial of all the affections; it changes its object perpetually; it has an appetite which is very sharp, but very easily satisfied; and it has always an appearance of giddiness, restlessness, and anxiety. Curiosity, from its nature, is a very active principle; it quickly runs over the greatest part of its objects; and soon exhausts the variety which is commonly to be met with in nature; the same things make frequent returns, and they return with less and less of any agreeable effect.
