More interesting, perhaps, it is to note the misconception of reason and knowledge which grew up. Knowledge came more and more to be identified with the reflective and critical consciousness, which is outside reality and life, and judges it from a standpoint of its own. It came to be esteemed only in its formal and abstract shape, and at the expense of the heart and feelings. The antithesis of philosophy (or knowledge strictly so called) according to Plato was mere opinion, accidental and imperfect knowledge. The knowledge which is truly valuable is a knowledge which presupposes the full reality of life, and is the more and more completely articulated theory of it as a whole. It is—abstractly taken—a mere form of unity which has no value except in uniting: it is—taken concretely—the matter, we may say, in complete unity. It is ideal and perfect harmony of thought, appetite, and emotion: or putting it otherwise, the philosopher is one who is not merely a creature of appetite and production, not merely a creature of feeling and practical energy, but a creature, who to both of these superadds an intelligence which sets eyes in the blind forehead of these other powers, and thus, far from superseding them altogether, only raises them into completeness, and realises all that is worthy in their implicit natures. Always these two impulsive tendencies of our nature are guided by some sort of ideas and intelligence, by beliefs and opinions. But they, like their guides, are sporadically emergent, unconnected, and therefore apt to be contradictory. It is to such erratic and occasional ideas, half-truths and deceptions, that philosophy is opposed. Unfortunately for all parties, the antithesis is carried farther. Philosophy and the philosopher are further set in opposition to the faith of the heart, the intimacy and intensity of feeling, the depth of love and trust, which in practice often go along with imperfect ideas. The philosopher is made one who has emancipated himself from the heart and feelings,—a pure intelligence, who is set above all creeds, contemplating all, and holding none. Consistency and clearness become his idol, to be worshipped at any cost, save one sacrifice: and that one sacrifice is the sacrifice of his own self-conceit. For consistency generally means that all is made to harmonise with one assumed standpoint, and that whatever presents discrepancies with this alleged standard is ruthlessly thrown away. Such a philosophy mistakes its function, which is not, as Heine scoffs, to make an intelligible system by rejecting the discordant fragments of life, but to follow reverently, if slowly, in the wake of experience. Such a “perfect sage,” with his parade of reasonableness, may often assume the post of a dictator.
