[M]an is not permitted without censure to follow his own thoughts in the search of truth, when they lead him ever so little out of the common road. - John Locke

There are indeed in some writers visible instances of deep thoughts, close and acute reasoning, and ideas well pursued. The light these would give, would be of great use, if their readers would observe and imitate them; all the rest at best are but particulars fit to be turned into knowledge, but that can be done only by our own meditation, and examining the reach, force, and coherence of what is said; and then, as far as we apprehend and see the connection of ideas, so far it is ours; without that, it is but so much loose matter floating in our brain. The memory may be stored, but the judgment is little better, and the stock of knowledge not increased, by being able to repeat what others have said or produce the arguments we have found in them. Such a knowledge as this is but knowledge by hearsay, and the ostentation of it is at best but talking by rote, and very often upon weak and wrong principles. For all that is to be found in books is not built upon true foundations, nor always rightly deduced from the principles it is pretended to be built on.

God gave the World to Men in Common; But since he gave it them for their benefit, and the greatest Conveniencies of life they were capable to draw from it, it cannot be supposed he meant it should always remain common and uncultivated. He gave it to the use of the industrious and Rational, (and Labour was to be his Title to it;) not to the fancy or covetousness of the quarrelsome and contentious.
