QUOTE : Kant’s teaching produces a fundamental change in every mind that has grasped it. The change is so great that it may be regarded as an intellectual rebirth. It alone is capable of really removing the inborn realism which arises from the original disposition of the intellect. Neither Berkeley nor Malebranche is competent to do this, for these men remain too much in the universal, whereas Kant goes into the particular. And this he does in a way which is unexpected either before or after him, and one which has quite a peculiar, one might say immediate, effect on the mind. In consequence of this, the mind undergoes a fundamental undeceiving, and thereafter looks at all things in another light. But only in this way does man become susceptible to the more positive explanations that I am going to give. On the other hand, the man who has not mastered the Kantian philosophy, whatever else he may studied, is, so to speak, in a state of innocence; in other words, he has remained in the grasp of that natural and childlike realism in which we are all born, and which qualifies one for every possible thing except philosophy.
