As a convenient way of entering into the study of their differences, I may refer to a recent article by Professor Jacks of Manchester College. Professor Jacks, in some brilliant pages in the 'Hibbert Journal' for last October, studies the relation between the universe and the philosopher who describes and defines it for us. You may assume two cases, he says. Either what the philosopher tells us is extraneous to the universe he is accounting for, an indifferent parasitic outgrowth, so to speak; or the fact of his philosophizing is itself one of the things taken account of in the philosophy, and self-included in the description. In the former case the philosopher means by the universe everything _except_ what his own presence brings; in the latter case his philosophy is itself an intimate part of the universe, and may be a part momentous enough to give a different turn to what the other parts signify. It may be a supreme reaction of the universe upon itself by which it rises to self-comprehension. It may handle itself differently in consequence of this event. Now both empiricism and absolutism bring the philosopher inside and make man intimate, but the one being pluralistic and the other monistic, they do so in differing ways that need much explanation. Let me then contrast the one with the other way of representing the status of the human thinker. For monism the world is no collection, but one great all-inclusive fact outside of which is nothing--nothing is its only alternative. When the monism is idealistic, this all-enveloping fact is represented as an absolute mind that makes the partial facts by thinking them, just as we make objects in a dream by dreaming them, or personages in a story by imagining them. To _be_, on this scheme, is, on the part of a finite thing, to be an object for the absolute; and on the part of the absolute it is to be the thinker of that assemblage of objects. If we use the word 'content' here, we see that the absolute and the world have an identical content. The absolute is nothing but the knowledge of those objects; the objects are nothing but what the absolute knows. The world and the all-thinker thus compenetrate and soak each other up without residuum. They are but two names for the same identical material, considered now from the subjective, and now from the objective point of view--gedanke and gedachtes, as we would say if we were Germans. We philosophers naturally form part of the material, on the monistic scheme. The absolute makes us by thinking us, and if we ourselves are enlightened enough to be believers in the absolute, one may then say that our philosophizing is one of the ways in which the absolute is conscious of itself. This is the full pantheistic scheme, the _identitätsphilosophie_, the immanence of God in his creation, a conception sublime from its tremendous unity. And yet that unity is incomplete, as closer examination will show.
