Should any one be disposed to think that questions of this sort (p. 382) might well be left undecided, and that the settlement of them is not worth the trouble and research often required for their thorough investigation, the Author ventures to suspect that, in the generality of instances, such reflections originate in an inexperience of the vast practical moment which facts, the most trifling in themselves, often carry with them in the investigation of the most important questions. Doubtless, the wise man will exercise his discretion in not confounding great things with small; but, on the contrary, in stamping on every thing its own intrinsic and comparative value. Still, in great things and small, (though each in its own weight and measure,) the truth is ever dear for its own sake, and should be for its own sake pursued. And it must never be forgotten, that one truth, in itself perhaps too minute and insignificant for its worth to be felt in the calculation, when probabilities are being estimated, may be a guiding star to other truths of great value, which, without its leading, might have remained neglected and unknown. In itself, a false statement, though generally acquiesced in, may be unimportant; in its consequences, it may be widely and permanently prejudicial to the cause of truth. If viewed abstractedly, it might appear like a cloud in the horizon not larger than a man's hand; but that speck may be the harbinger of wind and tempest. With regard, indeed, to those natural appearances in the sky, the most experienced observer can do nothing towards arresting the progress of the threatened storm; his (p. 383) foresight can only enable him to provide himself a shelter, or hasten him on his journey, "that the rain stop him not." In the case of literary, physical, moral, religious, and historical subjects of inquiry, (or to whatever department of human knowledge our pursuits may be directed,) by rectifying the minutest error we may check the propagation of mischief, and preserve the truth (it may be some momentous practical truth) in its integrity and brightness. * * * * *
