The significant sentence which occurs in the second volume of his work, closely following the announcement of his disappointment at being unable to achieve all that he had expected and promised, and which states that 'in a complete scheme of our knowledge, and when all our resources are fully developed and marshalled into order, as they must eventually be, the two methods [the Inductive and the Deductive] will be, not hostile, but supplementary, and will be combined into a single system,' seems to indicate that at some period prior to the publication of the second volume, and subsequent to the issue of the first, the insufficient nature of the Inductive Method as a Scientific guide broke upon him, and some conception of the nature of a Mode of Reasoning which should combine the two Processes in just relations, began to dawn into his mind. That he obtained anything more than a faint glimpse of the true Method, is not likely. Had he done so, he would certainly have made some statement of the great results which would follow its inauguration, even if he could have refrained from bestowing one of his glowing and enraptured paragraphs upon the fairest and most entrancing vision of future achievement which the devotee of intellectual investigation will ever witness. It is probable, that in carrying on his investigations after the publication of the first volume of his work, finding it impossible to handle the accumulations of Facts necessary to his purpose, and discovering the inexactitude and insufficiency of his Generalizations in the ratio that the bounds of his field of inquiry enlarged, he was led to perceive the essential weakness and inadequacy of the Inductive Method, and the probable certainty that, at some future period, the progress of our Knowledge would lead to the establishment of positive bases for all departments of investigation, and thus furnish an opportunity for the harmonious and reciprocal activity of the two hitherto antagonistic Methods. That he had any definite idea of the precise nature of the bases on which this union would take place, that he perceived the exact character of the Science of Universology which it would create, or contemplated the subordination of the Inductive Process to the Deductive, there is no indication. But whatever may have been Mr. Buckle's understanding or expectation in reference to the future, it is certain that between the publication of the first and second volumes of his History, the hope which he had formed and announced of being able to create a Science of History had vanished, and his efforts were confined to a less extensive programme. The pages in which this change of purpose is made known display, in touching outlines, tinged with a noble sadness, that the soul of the great Englishman was, in all the attributes of magnanimity, at least, a fitting mate for his intellect.
