Philosophy, let it be repeated, cannot "solve" the problem of the relation of the ideal and the real. That is the standing problem of life. But it can at least lighten the burden of humanity in dealing with the problem by emancipating mankind from the errors which philosophy has itself fostered--the existence of conditions which are real apart from their movement into something new and different, and the existence of ideals, spirit and reason independent of the possibilities of the material and physical. For as long as humanity is committed to this radically false bias, it will walk forward with blinded eyes and bound limbs. And philosophy can effect, if it will, something more than this negative task. It can make it easier for mankind to take the right steps in action by making it clear that a sympathetic and integral intelligence brought to bear upon the observation and understanding of concrete social events and forces, can form ideals, that is aims, which shall not be either illusions or mere emotional compensations. CHAPTER VI THE SIGNIFICANCE OF LOGICAL RECONSTRUCTION Logic--like philosophy itself--suffers from a curious oscillation. It is elevated into the supreme and legislative science only to fall into the trivial estate of keeper of such statements as A is A and the scholastic verses for the syllogistic rules. It claims power to state the laws of the ultimate structure of the universe, on the ground that it deals with the laws of thought which are the laws according to which Reason has formed the world. Then it limits its pretensions to laws of correct reasoning which is correct even though it leads to no matter of fact, or even to material falsity. It is regarded by the modern objective idealist as the adequate substitute for ancient ontological metaphysics; but others treat it as that branch of rhetoric which teaches proficiency in argumentation. For a time a superficial compromise equilibrium was maintained wherein the logic of formal demonstration which the Middle Ages extracted from Aristotle was supplemented by an inductive logic of discovery of truth that Mill extracted from the practice of scientific men. But students of German philosophy, of mathematics, and of psychology, no matter how much they attacked one another, have made common cause in attack upon the orthodox logics both of deductive proof and inductive discovery.
