But, what Fichte forgot was the consideration that the Ego cannot make any genuine, well-grounded decision or choice, unless something is presupposed which helps the Ego to choose. All the Ego's attempts at determination remain empty and without content, if the Ego does not find something wholly determinate and full of content, which enables it to determine the Given, and thereby also to choose between Idealism and Dogmatism. This "something wholly determinate and full of content" is, precisely, the world of Thought. And the determination of the Given by thinking is, precisely, what we call cognition. We may take Fichte where we please--everywhere we find that his line of thought at once gets meaning and substance, as soon as we conceive his grey, empty activity of the Ego to be filled and regulated by what we have called "the process of cognition." The fact that the Ego is free to enter into activity out of itself, makes it possible for it, by free self-determination, to realise the category of cognition, whereas in the rest of the world all categories are connected by objective necessity with the Given which corresponds to them. The investigation of the nature of free self-determination will be the task of Ethics and Metaphysics, based on our Theory of Knowledge. These disciplines, too, will have to debate the question whether the Ego is able to realise other ideas, besides the idea of cognition. But, that the realisation of the idea of cognition issues from a free act has been made sufficiently clear in the course of our discussions above. For, the synthesis, effected by the Ego, of the Immediately-Given and of the Form of Thought appropriate to it, which two factors of reality remain otherwise always divorced from each other in consciousness, can be brought about only by an act of freedom. Moreover, our arguments throw, in another way, quite a fresh light on Critical Idealism. To any close student of Fichte's system it will appear as if Fichte cared for nothing so much as for the defence of the proposition, that nothing can enter the Ego from without, that nothing can appear in the Ego which was not the Ego's own original creation. Now, it is beyond all dispute that no type of Idealism will ever be able to derive from within the Ego that form of the world-content which we have called "the Immediately-Given." For, this form can only be given; it can never be constructed by thinking. In proof of this, it is enough to reflect that, even if the whole series of colours were given to us except one, we should not be able to fill in that one out of the bare Ego. We can form an image of the most remote countries, though we have never seen them, provided we have once personally experienced, as given, the details which go to form the image. We then build up the total picture, according to the instructions supplied to us, out of the particular facts which we have ourselves experienced. But we shall
