Now, it may be objected that we have already piled up a whole host of thought-determinations in the very process of extracting the alleged primitive world-picture out of the complete picture into which man's cognitive elaboration has transformed it. But, in defence we must urge that all our conceptual apparatus was employed, not for the characterisation of the primitive world-picture, nor for the determination of its qualities, but solely for the guidance of our analysis, in order to lead it to the point where knowledge recognises that it began. Hence, there can be no question of the truth or error, correctness or incorrectness, of the reflections which, according to our view, precede the moment which brings us to the starting-point of the Theory of Knowledge. Their purpose is solely to guide us conveniently to that point. Nobody who is about to occupy himself with epistemological problems, stands at the same time at what we have rightly called the starting-point of knowledge, for his knowledge is already, up to a certain degree, developed. Nothing but analysis with the help of concepts enables us to eliminate from our developed knowledge all the gains of cognitive activity and to determine the starting-point which precedes all such activity. But the concepts thus employed have no cognitive value. They have the purely negative task to eliminate out of our field of vision whatever is the result of cognitive activity and to lead us to the point where this activity first begins. The present discussions point the way to those primitive beginnings upon which the cognitive activity sets to work, but they form no part of such activity. Thus, whatever Theory of Knowledge has to say in the process of determining the starting-point, must be judged, not as true or false, but only as fit or unfit for this purpose. Error is excluded, too, from that starting-point itself. For, error can begin only with the activity of cognition; prior to this, it cannot occur. This last proposition is compatible only with the kind of Theory of Knowledge which sets out from our line of thought. For, a theory which sets out from some object (or subject) with a definite conceptual determination is liable to error from the very start, viz., in this very determination. Whether this determination is justified or not, depends on the laws which the cognitive act establishes. This is a question to which only the course of the epistemological inquiry itself can supply the answer. All error is excluded only when I can say that I have eliminated all conceptual determinations which are the results of my cognitive activity, and that I retain nothing but what enters the circle of my experience without any activity on my part. Where, on principle, I abstain from every positive affirmation, there I cannot fall into error.
