Summary

The greatest part of mankind may be divided into two classes; that of shallow thinkers, who fall short of the truth; and that of abstruse thinkers, who go beyond it. The latter class are by far the most uncommon; and I may add, by far the most useful and valuable. They suggest hints, at least, and start difficulties, which they want, perhaps, skill to pursue; but which may produce fine discoveries, when handled by men who have a more just way of thinking. At worst, what they say is uncommon; and if it should cost some pains to comprehend it, one has, however, the pleasure of hearing something that is new. An author is little to be valued, who tells us nothing but what we can learn from every coffeehouse conversation.

All people of shallow thought are apt to decry even those of solid understanding, as abstruse thinkers, and metaphysicians, and refiners; and never will allow any thing to be just which is beyond their own weak conceptions. There are some cases, I own, where an extraordinary refinement affords a strong presumption of falsehood, and where no reasoning is to be trusted but what is natural and easy. When a man deliberates concerning his conduct in any particular affair, and forms schemes in politics, trade, oeconomy, or any business in life, he never ought to draw his arguments too fine, or connect too long a chain of consequences together. Something is sure to happen, that will disconcert his reasoning, and produce an event different from what he expected.
