positions into which one of the most vigorous and acute of modern logicians, Lotze, has been forced through failing to define logical distinctions in terms of the history of readjustment and control of things in experience, and being thereby compelled to interpret certain notions as absolute instead of as historic and methodological. Before passing directly to the exposition and criticism of Lotze, it will be well, however, to take the matter in a somewhat freer way. We cannot approach logical inquiry in a wholly direct and uncompromised manner. Of necessity we bring to it certain distinctions--distinctions partly the outcome of concrete experience; partly due to the logical theory which has got embodied in ordinary language and in current intellectual habits; partly results of deliberate scientific and philosophic inquiry. These more or less ready-made results are resources; they are the only weapons with which we can attack the new problem. Yet they are full of unexamined assumptions; they commit us to all sorts of logically predetermined conclusions. In one sense our study of the new subject-matter, let us say logical theory, is in truth only a review, a retesting and criticizing of the intellectual standpoints and methods which we bring with us to the study. Nowadays everyone comes with certain distinctions already made between the subjective and the objective, between the physical and the mental, between the intellectual and the factual. (1) We have learned to regard the region of emotional disturbance, of uncertainty and aspiration, as belonging peculiarly to ourselves; we have learned to set over against this the world of observation and of valid thought as something unaffected by our moods, hopes, fears, and opinions. (2) We have also come to distinguish between what is immediately present in our experience and the past and the future; we contrast the realms of memory and anticipation with that of sense perception; more generally we contrast the given with the inferential. (3) We are confirmed in a habit of distinguishing between what we call actual fact and our mental attitude toward that fact--the attitude of surmise or wonder or reflective investigation. While one of the aims of logical theory is precisely to make us critically conscious of the significance and bearing of these various distinctions, to change them from ready-made assumptions into controlled conceptions, our mental habits are so set that they tend to have their own way with us; we read into logical theory conceptions that were formed before we had even dreamed of the logical undertaking which after all has for its business to assign to the terms in question their proper meaning. Our conclusions are thus controlled by the very notions which need criticism and revision.
