Along these different paths the complementary potentialities are produced and intensified, separating in the very process, their original interpretation being possible only in the state of birth. One of them ends in what we call intelligence. This latter therefore has become gradually detached from a less intense but fuller luminous condition, of which it has retained only certain characteristics to accentuate them.

We see that we must conceive the word mind—or, if we prefer the word, thought—as extending beyond intelligence. Pure intelligence, or the faculty of critical reflection and conceptual analysis, represents only one form of thought in its entirety, a function, a determination or particular adaptation, the part organised in view of practical action, the part consolidated as language. What are its characteristics? It understands only what is discontinuous, inert, and fixed, that which has neither change nor duration; it bathes in an atmosphere of spatiality; it uses mathematics continually; it feels at home only among "things," and everything is reduced by it to solid atoms; it is naturally "materialist," owing to the very fact that it naturally grasps "forms" only. What do we mean by that except that its object of election is the mechanism of matter? But it supposes life; it only remains living itself by continual loans from a vaster and fuller activity from which it is sprung. And this return to complementary powers is what we call intuition.

From this point of view it becomes easy to escape Kantian relativity. We are confronted by an intelligence which is doubtless no longer a faculty universally competent, but which, on the contrary, possesses in its own domain a greater power of penetration. It is arranged for action. Now action would not be able to move in irreality. Intelligence, then, makes us acquainted, if not with all reality, at least with some of it, namely that part by which reality is a possible object of mechanical or synthetic action.

More profoundly, intuition falls into analysis as life into matter: they are two aspects of the same movement. That is why, "provided we only consider the general form of physics, we can say that it touches the absolute." ("Creative Evolution", page 216.)

In other terms, language and mechanism are regulated by each other. This explains at once the success of mathematical science in the order of matter, and its non-success in the order of life.

For, when confronted with life, intelligence fails. "Being a deposit of the evolutive movement along its path, how could it be applied throughout the evolutive movement itself? We might as well claim that the part equals the whole, that the effect can absorb its cause into itself, or that the pebble left on the shore outlines the form of the wave which brought it." (Preface to "Creative Evolution".)

Is not that as good as saying that life is unknowable? Must we conclude that it is impossible to understand it?

"We should be forced to do so, if life had employed all the psychic potentialities it contains in making pure understandings; that is to say, in preparing mathematicians. But the line of evolution which ends in man is not the only one. By other divergent ways other forms of consciousness have developed, which have not been able to free themselves from external constraint, nor regain the victory over themselves as intelligence has done, but which, none the less for that, also express something immanent and essential in the movement of evolution.

"By bringing them into connection with one another, and making them afterwards amalgamate with intelligence, should we not thus obtain a consciousness co-extensive with life, and capable, by turning sharply round upon the vital thrust which it feels behind it, of obtaining a complete, though doubtless vanishing vision?" ("Creative Evolution", Preface.) It is precisely in this that the act of philosophic intuition consists. "We shall be told that, even so, we do not get beyond our intelligence, since it is with our intelligence, and through our intelligence, that we observe all the other forms of consciousness. And we should be right in saying so, if we were pure intelligences, if there had not remained round our conceptual and logical thought a vague nebula, made of the very substance at the expense of which the luminous nucleus, which we call intelligence, has been formed. In it reside certain complementary powers of the understanding, of which we have only a confused feeling when we remain shut up in ourselves, but which will become illumined and distinct when they perceive themselves at work, so to speak, in the evolution of nature. They will thus learn what effort they have to make to become more intense, and to expand in the actual direction of life." ("Creative Evolution", Preface.) Does that mean abandonment to instinct, and descent with it into infra-consciousness again? By no means. On the contrary, our task is to bring instinct to enrich intelligence, to become free and illumined in it; and this ascent towards super-consciousness is possible in the flash of an intuitive act, as it is sometimes possible for the eye to perceive, as a pale and fugitive gleam, beyond what we properly term light, the ultra-violet rays of the spectrum.

Can we say of such a doctrine that it seeks to go, or that it goes "against intelligence"? Nothing authorises such an accusation, for limitation of a sphere is not misappreciation of every legitimate exercise. But intelligence is not the whole of thought, and its natural products do not completely exhaust or manifest our power of light.
