There is a point of view, indeed, from which the matter appears under a different aspect, and is really different. To the all-seeing eye of Providence, every human life, however brief its duration, however apparently insignificant, presents a point of internal development and crisis, consequently a species of history, cognizable and visible to that Eye only, and therefore not entirely without an object. But this point of view belongs to another order of things, and is no longer historical--it has reference to the immortal destinies of the human soul, and the connection of the present life with another world invisible to us. But our historical science is limited to the department of man's present existence; and in our historical enquiries we must not lose sight of this principle. But the internal development of mind, so far as it is historical, belongs as much as the external events of politics to the department of human history, and must by no means be excluded from it. Among these rare exceptions of historical men, must be named that ancient master of human acuteness who was the teacher of Alexander the Great, and who perhaps holds not an humbler or less important place in this exalted sphere than the conqueror himself, although this philosopher, whose genius embraced nature, the world and life, was by his own contemporaries less honoured and celebrated than by a remote posterity. Here in our western world, and long after the kingdoms founded by the Macedonian conqueror had disappeared, and were forgotten, Aristotle for many centuries reigned the absolute lord of the Christian schools, and directed the march of human science and human speculation in the middle age. Whether he were always rightly understood and studied in the right way is another question, for here we are speaking of his overruling influence and historical importance. Nay, in later times, he has materially served the cause of the better natural philosophy founded on experience, in which he himself accomplished things so extraordinary for his age, and was originally, and for a long while, the guide and master.
