 vulgar, also says, that subtle truths are those which have the least substance in them, and consequently approach nearest to nonentity. But for my own part I cannot help thinking that the most important truths must be the most refined and subtle; for that very reason, that they must comprehend a great number of particulars, and instead of referring to any distinct or positive fact, must point out the combined effects of an extensive chain of causes, operating gradually, remotely, and collectively, and therefore imperceptibly.

The very same persons who are the most forward to laugh at all systematic reasoning as idle and impertinent, you will the next moment hear exclaiming bitterly against the baleful effects of new-fangled systems of philosophy, or gravely descanting on the immense importance of instilling sound principles of morality into the mind. It would not be a bold conjecture, but an obvious truism to say, that all the great changes which have been brought about in the moral world, either for the better or worse, have been introduced not by the bare statement of facts, which are things already known, and which must always operate nearly in the same manner, but by the development of certain opinions and abstract principles of reasoning on life and manners, on the origin of society and man's nature in general, which being obscure and uncertain, vary from time to time, and produce correspondent changes in the human mind. They are the wholesome dew and rain, or the mildew and pestilence that silently destroy.
