Thus we now meet the view very usually taken of the history of Philosophy which ascribes to it the narration of a number of philosophical opinions as they have arisen and manifested themselves in time. This kind of matter is in courtesy called opinions; those who think themselves more capable of judging rightly, call such a history a display of senseless follies, or at least of errors made by men engrossed in thought and in mere ideas. This view is not only held by those who recognize their ignorance of Philosophy. Those who do this, acknowledge it, because that ignorance is, in common estimation, held to be no obstacle to giving judgment upon what has to do with the subject; for it is thought that anybody can form a judgment on its character and value without any comprehension, of it whatever. But the same view is even held by those who write or have written on the history of Philosophy. This history, considered only as the enumeration of various opinions, thus becomes an idle tale, or, if you will, an erudite investigation. For erudition is, in the main, acquaintance with a number of useless things, that is to say, with that which has no intrinsic interest or value further than being known. Yet it is thought that profit is to be derived from learning the various opinions and reflections of other men. It stimulates the powers of thought and also leads to many excellent reflections; this signifies that now and then it occasions an idea, and its art thus consists in the spinning one opinion out of the other. If the history of Philosophy merely represented various opinions in array, whether they be of God or of natural and spiritual things existent, it would be a most superfluous and tiresome science, no matter what advantage might be brought forward as derived from such thought-activity and learning. What can be more useless than to learn a string of bald opinions, and what more unimportant? Literary works, being histories of Philosophy in the sense that they produce and treat the ideas of Philosophy as if they were opinions, need be only superficially glanced at to find how dry and destitute of interest everything about them is. An opinion is a subjective conception, an uncontrolled thought, an idea which may occur to me in one direction or in another: an opinion is mine,[3] it is in itself a universal thought which is existent in and for itself. But Philosophy possesses no opinions, for there is no such thing as philosophical opinions. When we hear a man speaking of philosophical opinions, even though he be an historian of philosophy itself, we detect at once this want of fundamental education. Philosophy is the objective science of truth, it is science of necessity, conceiving knowledge, and neither opinion nor the spinning out of opinions.
