Knowledge is always Judgment. Judgment is constructive, for us, of the real world. Constructing the real world means interpreting or amplifying our present perception by what we are obliged to think, which we take as all belonging to a single system one with itself, and with what constrains us in sense-perception, and objective in the sense that its parts act on each other independently of our individual apprehension, and that we are obliged to think them thus. The process of construction is always that of exhibiting a whole in its parts, _i.e._ an identity in its differences; that is to say, it is always both analytic and synthetic. The objects of knowledge differ in the mode of relation between their {59} parts and the whole, and thus give rise to different types of judgment and inference; and this difference in the form of knowledge is a difference in the content of Logic, which deals with the objects of experience only from the point of view of their properties as objects in an intellectual world. _Conclusion_ 5. I hope that these general lectures, which, as I am quite aware, have anticipated the treatment of many difficult questions which they have not attempted to solve, have been successful in putting the problem of Logic before us with some degree of vividness. If this problem were thoroughly impressed upon our minds, I should say that we had already gained something definite from this course of study. The points which I desire to emphasise are two. (1) I hope that we have learned to realise the world of our knowledge as a living growth, sustained by the energy of our intelligence; and to understand that we do not start with a ready-made world in common, but can only enter upon the inheritance of science and civilisation as the result of courage, labour, and reasonable perseverance; and further, that we retain this inheritance just as long as our endurance and capacity hold out, and no longer. And (2) I have attempted to make clear that this living growth, our knowledge, is like the vegetable or animal world in being composed of infinite minor systems, each and all of which are at bottom the same function with corresponding parts or elements, modified by adaption to the environment. So that the task of analysing the form of judgment bears a certain resemblance to that of analysing the forms of plants. Just as from the single cell of the undifferentiated Alga, to {60} the most highly organised flower or tree, we have the same formation, with its characteristic functions and operations, so from the undifferentiated judgment, which in linguistic form resembles an ejaculation or interjection, to the reasonable systems of exact or philosophical science, we find the same systematic function with corresponding elements.
