Intelligence is accordingly conditioned by a modification of both structure and consciousness by dint of past events. To be aware that a second stroke is not itself the first, I must retain something of the old sensation. The first must reverberate still in my ears when the second arrives, so that this second, coming into a consciousness still filled by the first, is a different experience from the first, which fell into a mind perfectly empty and unprepared. Now the newcomer finds in the subsisting One a sponsor to christen it by the name of Two. The first stroke was a simple 1. The second is not simply another 1, a mere iteration of the first. It is 11, where the coefficient represents the reverberating first stroke, still persisting in the mind, and forming a background and perspective against which the new stroke may be distinguished. The meaning of "two," then, is "this after that" or "this again," where we have a simultaneous sense of two things which have been separately perceived but are identified as similar in their nature. Repetition must cease to be pure repetition and become cumulative before it can give rise to the consciousness of repetition.
The first condition of counting, then, is that the sensorium should retain something of the first impression while it receives the second, or (to state the corresponding mental fact) that the second sensation should be felt together with a survival of the first from which it is distinguished in point of existence and with which it is identified in point of character.
No identical agent needed.
Now, to secure this, it is not enough that the sensorium should be materially continuous, or that a "spiritual substance" or a "transcendental ego" should persist in time to receive the second sensation after having received and registered the first. A perfectly elastic sensorium, a wholly unchanging soul, or a quite absolute ego might remain perfectly identical with itself through various experiences without collating them. It would then remain, in fact, more truly and literally identical than if it were modified somewhat by those successive shocks. Yet a sensorium or a spirit thus unchanged would be incapable of memory, unfit to connect a past perception with one present or to become aware of their relation. It is not identity in the substance impressed, but growing complication in the phenomenon presented, that makes possible a sense of diversity and relation between things. The identity of substance or spirit, if it were absolute, would indeed prevent comparison, because it would exclude modifications, and it is the survival of past modifications within the present that makes comparisons possible. We may impress any number of forms successively on the same water, and the identity of the substance will not help those forms to survive and accumulate their effects. But if we have a surface that retains our successive stampings we may change the substance from wax to plaster and from plaster to bronze, and the effects of our labour will survive and be superimposed upon one another. It is the actual plastic form in both mind and body, not any unchanging substance or agent, that is efficacious in perpetuating thought and gathering experience.
Example of the sun.
Were not Nature and all her parts such models of patience and pertinacity, they never would have succeeded in impressing their existence on something so volatile and irresponsible as thought is. A sensation needs to be violent, like the sun's blinding light, to arrest attention, and keep it taut, as it were, long enough for the system to acquire a respectful attitude, and grow predisposed to resume it. A repetition of that sensation will thereafter meet with a prepared response which we call recognition; the concomitants of the old experience will form themselves afresh about the new one and by their convergence give it a sort of welcome and interpretation. The movement, for instance, by which the face was raised toward the heavens was perhaps one element which added to the first sensation, brightness, a concomitant sensation, height; the brightness was not bright merely, but high. Now when the brightness reappears the face will more quickly be lifted up; the place where the brightness shone will be looked for; the brightness will have acquired a claim to be placed somewhere. The heat which at the same moment may have burned the forehead will also be expected and, when felt, projected into the brightness, which will now be hot as well as high. So with whatever other sensations time may associate with this group. They will all adhere to the original impression, enriching it with an individuality which will render it before long a familiar complex in experience, and one easy to recognise and to complete in idea.
His primitive divinity.
In the case of so vivid a thing as the sun's brightness many other sensations beside those out of which science draws the qualities attributed to that heavenly body adhere in the primitive mind to the phenomenon. Before he is a substance the sun is a god. He is beneficent and necessary no less than bright and high; he rises upon all happy opportunities and sets upon all terrors. He is divine, since all life and fruitfulness hang upon his miraculous revolutions. His coming and going are life and death to the world. As the sensations of light and heat are projected upward together to become attributes of his body, so the feelings of pleasure, safety, and hope which he brings into the soul are projected into his spirit; and to this spirit, more than to anything else, energy, independence, and substantiality are originally attributed. The emotions felt in his presence being the ultimate issue and term of his effect in us, the counterpart or shadow of those emotions is regarded as the first and deepest factor in his causality. It is his divine life, more than aught else, that underlies his apparitions and explains the influences which he propagates. The substance or independent existence attributed to objects is therefore by no means only or primarily a physical notion. What is conceived to support the physical qualities is a pseudo-psychic or vital force. It is a moral and living object that we construct, building it up out of all the materials, emotional, intellectual, and sensuous, which lie at hand in our consciousness to be synthesised into the hybrid reality which we are to fancy confronting us. To discriminate and redistribute those miscellaneous physical and psychical elements, and to divorce the god from the material sun, is a much later problem, arising at a different and more reflective stage in the Life of Reason.
Causes and essences contrasted.
When reflection, turning to the comprehension of a chaotic experience, busies itself about recurrences, when it seeks to normalise in some way things coming and going, and to straighten out the causes of events, that reflection is inevitably turned toward something dynamic and independent, and can have no successful issue except in mechanical science. When on the other hand reflection stops to challenge and question the fleeting object, not so much to prepare for its possible return as to conceive its present nature, this reflection is turned no less unmistakably in the direction of ideas, and will terminate in logic or the morphology of being. We attribute independence to things in order to normalise their recurrence. We attribute essences to them in order to normalise their manifestations or constitution. Independence will ultimately turn out to be an assumed constancy in material processes, essence an assumed constancy in ideal meanings or points of reference in discourse. The one marks the systematic distribution of objects, the other their settled character.
Voracity of intellect.
We talk of recurrent perceptions, but materially considered no perception recurs. Each recurrence is one of a finite series and holds for ever its place and number in that series. Yet human attention, while it can survey several simultaneous impressions and find them similar, cannot keep them distinct if they grow too numerous. The mind has a native bias and inveterate preference for form and identification. Water does not run down hill more persistently than attention turns experience into constant terms. The several repetitions of one essence given in consciousness will tend at once to be neglected, and only the essence itself—the character shared by those sundry perceptions—will stand and become a term in mental discourse. After a few strokes of the clock, the reiterated impressions merge and cover one another; we lose count and perceive the quality and rhythm but not the number
