“It is hard to know what other way men can come to truth, to lay hold of it, if they do not dig and search for it as for gold and hid treasure; but he that does so, must have much earth and rubbish, before he gets the pure metal; sand, and pebbles, and dross usually lie blended with it, but the gold is nevertheless gold, and will enrich the man that employs his pains to seek and separate it.”

“If the Gospel and the Apostles may be credited, no man can be a Christian without charity, and without that faith which works, not by force, but by love.”

“Every man carries about him a touchstone, if he will make use of it, to distinguish substantial gold from superficial glitterings, truth from appearances. And indeed the use and benefit of this touchstone, which is natural reason, is spoiled and lost only by assuming prejudices, overweening presumption, and narrowing our minds.”

“Brutes abstract not. -- If it may be doubted, whether beasts compound and enlarge their ideas, that way, to any degree; this, I think, I may be positive in, that the power of abstracting is not at all in them; and that the having of general ideas is that which puts a perfect distinction betwixt man and brutes, and is an excellency which the faculties of brutes do by no means attain to.”

“A father would do well, as his son grows up, and is capable of it, to talk familiarly with him; nay, ask his advice, and consult with him about those things wherein he has any knowledge or understanding. By this, the father will gain two things, both of great moment. The sooner you treat him as a man, the sooner he will begin to be one; and if you admit him into serious discourses sometimes with you, you will insensibly raise his mind above the usual amusements of youth, and those trifling occupations which it is commonly wasted in.”
“As it is in the body, so it is in the mind; practice makes it what it is, and most even of those excellencies, what are looked on as natural endowments, will be found, when examined into more narrowly, to be the product of exercise, and to be raised to that pitch, only by repeated actions.”

“The native and untaught suggestions of inquisitive children do often offer things, that may set a considering man's thoughts on work. And I think there is frequently more to be learn'd from the unexpected questions of a child than the discourses of men, who talk in a road, according to the notions they have borrowed, and the prejudices of their education.”
