We come now to the second proposition which we laid down, and that is, that out of his own language, there are no other two languages whose literature holds out as many inducements to the student for acquiring them, as that of the Greek and Latin languages, since independently of their own worth, these studies are absolutely essential to the proper understanding of modern literature as it now exists. Surely there could exist no opinion more unfortunate for the progress of science, than that which supposes, that a view of science as it now exists, is all that is necessary for its thorough investigation; indeed, we believe the assertion may be safely hazarded, that no one can ever qualify himself for the race of discovery who looks alone to what men now think without a reference to what they have formerly believed and written upon the subjects of his inquiry. Strange as it may seem, the man who would ascertain truth, must not confine himself to the simple inquiry of what it is. He must also see what men have thought about it. He must look to the history of human opinion and the modes of reasoning by which men have arrived at their conclusions. He must not only be able to understand the results of right reason, but he must learn also to reason for himself. It was a perception of this necessity which induced the immortal Bacon to turn his attention to the mode of investigating truth, rather than to the discovery of truth itself. He perceived that it was the most important benefit which could be conferred by any man of that day, and the Novum Organon, the most wonderful of mere human conceptions, was the result. A view of the different modes of reasoning to truth which had been employed before him, a comparison of the methods which the most successful philosophers had pursued, soon taught him that there was as much in the method used as in the genius of the investigator. He who would pursue the path of truth, would do well to prepare himself with a guide book made up from the experience of former travellers; he will thus learn the various roads which intersect his true path, and might be likely to put him out, each of which some former pilgrim has taken before him, from whose recorded experience he may take warning; or sometimes it may happen that whilst the crowd of philosophers have been wandering for centuries through a mazy error, the account given by some long gone traveller of a partially explored route may lead the happy investigator into the true way, and thus forward him on his journey. In the progress of truth, which of necessity must be slow and cautious, it is important to weigh every step, and every chart should be preserved. It was thus that Copernicus, retracing the steps of philosophers for two thousand years, discovered in the almost forgotten accounts of the writings of Nicetas, Heraclides and Ecphontus, traces of a route into which he struck off and was
