Neither duality nor multiplicity is conceivable without that unity whereby the two engender that whole in which the two units are connected, even though they mutually exclude one another: without that unity which fuses and unifies every multiplicity determined in a number, which correlates among themselves the units which constitute the number. We could strip multiplicity of all unity only by not thinking it. But then in the gloom of what is not thought, multiplicity truly enough would not be unity, but it would not even be multiplicity, because it could not be anything at all. Or, if we prefer, it would be absolutely unthinkable.
Thought then establishes relationships among the units of the multiple, and thus constitutes them as the units of the manifold, and as forming multiplicity. It adds and divides, composes and decomposes, and variously distributes, materialising and dematerialising, 107 so to speak, the reality which it thinks. For it materialises the reality when it conceives it as manifold: but it can conceive it as such only by unifying it, and therefore by dematerialising it and reabsorbing it into its own spiritual substance.
Matter is a manifold reality, without unity. What it is we already have seen: a material reality, and as such divisible into parts, placed in the world in the midst of a congeneric multitude. Now, since pure multiplicity is not conceivable except on condition that we abstract from that relationship to which the reciprocal exclusiveness of manifold elements is reduced, it is evident that matter and things are abstract entities. Thought stops to consider them, and regards them as existent, only because it withdraws the attention from that part of itself which it contributes to the making of the object represented. Thought therefore prescinds from that unity which material things could not by themselves contain, but from which it is impossible to prescind absolutely unless we wish to be reduced to an absurd conception.
Objective things then, the world of matter itself which we are wont to oppose in equipoise to the person, are in truth not separable from it. For matter has its foundation in thought by which the personality is actualised. Things are what we in our own thought counterpose to ourselves who think them. Outside of our thought they are absolutely nothing. Their material 108 hardness itself has to be lent to them by us, for it ultimately is to be resolved into multiplicity, and multiplicity implies spiritual unity.
This then is the world: an infinity of things all of which have however their root in us. Not in “us” as we are represented ordinarily in the midst of things; not in the empirical and abstract “us” which feeds the vanity of the empty-headed egoist, of him who has not the faintest notion of what he really is, who can therefore think of himself only as enclosed within the tight husk of his own flesh and of his particular passions. No! they are rooted in that true “us” by which we think, and agree in one same thought, while thinking all things, including ourselves as opposed to things. And he who fails to reach this profound source, this root from which all reality receives its vitalising sap, may indeed get a blurred glimpse of a blind, inert, material mechanism, but he cannot even fix and determine this mechanism. He cannot upon further reflection stop at the conviction that it is in truth, as it appears in semblance, something real, for it reveals itself to him as so absurd as to become unthinkable. The world then is in us; it is our world, and it lives in the spirit. It lives the very life of that person which we strive to realise, sometimes satisfied with our work, but oftener unsatisfied and restless. And there is the life of culture.
It is not possible to conceive knowledge otherwise than as living knowledge, and as the extolment of our 109 own personality. This is our conclusion. We shall, later on, derive from it two corollaries that are very important for teachers, in as much as they bear directly on the problems of education.
