Nature has given every one a faculty of thought. But thought is all that philosophy claims as the form proper to her business: and thus the inadequate view which ignores the distinction stated in § 3, leads to a new delusion, the reverse of the complaint previously mentioned about the unintelligibility of philosophy. In other words, this science must often submit to the slight of hearing even people who have never taken any trouble with it talking as if they thoroughly understood all about it. With no preparation beyond an ordinary education they do not hesitate, especially under the influence of religious sentiment, to philosophise and to criticise philosophy. Everybody allows that to know any other science you must have first studied it, and that you can only claim to express a judgment upon it in virtue of such knowledge. Everybody allows that to make a shoe you must have learned and practised the craft of the shoemaker, though every man has a model in his own foot, and possesses in his hands the natural endowments for the operations required. For philosophy alone, it seems to be imagined, such study, care, and application are not in the least requisite. This comfortable view of what is required for a philosopher has recently received corroboration through the theory of immediate or intuitive knowledge. 6.] So much for the form of philosophical knowledge. It is no less desirable, on the other hand, that philosophy should understand that its content is no other than _actuality,_ that core of truth which, originally produced and producing itself within the precincts of the mental life, has become the _world,_ the inward and outward world, of consciousness. At first we become aware of these contents in what we call Experience. But even Experience, as it surveys the wide range of inward and outward existence, has sense enough to distinguish the mere appearance, which is transient and meaningless, from what in itself really deserves the name of actuality. As it is only in form that philosophy is distinguished from other modes of attaining an acquaintance with this same sum of being, it must necessarily be in harmony with actuality and experience. In fact, this harmony may be viewed as at least an extrinsic means of testing the truth of a philosophy. Similarly it may be held the highest and final aim of philosophic science to bring about, through the ascertainment of this harmony, a reconciliation of the self-conscious reason with the reason which _is_ in the world,--in other words, with actuality. In the preface to my Philosophy of Law, p. xix, are found the propositions: What is reasonable is actual; and, What is actual is reasonable.
