VIII—HOW PRODUCED

An imprint or mould of the object is generally left in the plasma of the subject. The imprint is deep, clear and lasting in proportion to the strength of the exciting cause and the degree of energy assigned to the perception. When the noumenon withdraws the object does not at once disappear, for if the energy of attention remain the mould left by the noumenon serves to excite a consciousness similar to the object, and this is what we call an Idea.

What Hume says as to an object differing from an idea in nothing but vividness is evidently incorrect. Objects are generally, but not always, more vivid than ideas, and when an object is present we have an indefeasible conviction of being acted on by something not ourselves, which conviction is not present in recollection. We may not be able to give a satisfactory reason for the conviction—if we are arguing idealistically we certainly shall not—but the fact that it is there serves to mark off objects as a class of consciousness distinct from ideas, irrespective of their vividness. If an object were once seen clearly and so remembered, and were afterwards seen indistinctly through a mist, the latter consciousness would (according to Hume) be the idea and the former the object. Such an application of words would be an abuse of language.

There are of course no innate ideas of objects. There is innate consciousness—the sentimental.

Ideas are of three kinds—Particular Ideas, General Ideas, Imaginary Ideas—corresponding to the so-called faculties of Memory, Generalisation or Classification, and Imagination.

IX—MEMORY OF OBJECTS

When the energy of attention is exhausted or withdrawn the idea also disappears, but it may be revived by bringing the energised Self in contact with the imprint again, and this operation can be repeated indefinitely. The power of exciting ideas of past experience is Memory; any particular exercise of memory is Recollection.

The imprint of an object is not absolutely permanent and is probably never quite true. It begins to lose sharpness at once, but if the object be frequently observed and much remembered, it will retain its general character for years. The exercise of memory, instead of wearing out the imprint as would be the case with a material negative or engraved plate, keeps the channels open⁶. Persons of little experience remember well, for their energy of attention is not distributed over many different ideas; it travels continuously round a small circuit. One hears ignorant persons recounting events that happened years ago, with as much detail and with almost as much sentiment as if they had taken place the day before. A 'good memory' is no proof that the quality of mind or thought is good. All experience is not worth remembering. One of the most difficult things in moral culture is to get rid of the imprints of ideas that are out of harmony with our improved sentiment.

Although the imprints in our mind may close up and leave scarce a cicatrice, the part that has been once disturbed is never the same as the virgin plasm. It remains a little more tender. It may not reopen to ordinary stimuli, but an extra agitation of the plasm will rip up the closed furrows, and give us back scenes in our life that had long ceased to be recollected. A great agitation in all parts of the mind may revive what appears to be the whole of our past experience in a simultaneous recollection. So I explain the extraordinary lucidity that sometimes occurs in fevers and in moments of extreme terror.

It is also conceivable that the egoistic energy may be so strong as to destroy outright the moulds of thought, as a flood sweeps away the banks of a river. 'We sometimes find a disease quite strip the mind of all its ideas, and the flames of a fever in a few days calcine all those images to dust and confusion which seemed to be as lasting as if graved in marble'⁷.

What is called 'decay of the mind' in old age is merely the loss of the plasmic images. Since intellect would not have been formed in the first instance if it had not been wanted, it is to be expected that it will fade out of the mind when it is no longer wanted. So far as the realistic intellect is concerned, we return to 'second childhood' and the uniform sensibility we had at birth.

No philosophy but the substantial explains memory. Idealists and metaphysicians, who recognise only consciousness, are utterly unable to account for the revival of a shadowy sort of objects in the absence of their original causes. Here is the melancholy confession of John Stuart Mill on the subject:—

'If we speak of the Mind as a series of feelings, we are obliged to complete the statement by calling it a series of feelings which is aware of itself as past and future: and we are reduced to the alternative of believing that the Mind, or Ego, is something different from any series of feelings, or possibilities of them, or of accepting the paradox that something which ex hypothesi is but a series of feelings, can be aware of itself as a series.

'The truth is that we are here face to face with that final inexplicability at which, as Sir W. Hamilton observes, we inevitably arrive when we reach ultimate facts; and in general one mode of stating it only appears more incomprehensible than another, because the whole of human language is accommodated to the one, and is so incongruous with the other, that it cannot be expressed in any terms which do not deny its truth. The real stumbling-block is perhaps not in any theory of the fact, but in the fact itself. The true incomprehensibility perhaps is, that something which has ceased, or is not yet in existence, can still be, in a manner, present: that a series of feelings, the infinitely greater part of which is past or future, can be gathered up as it were into a single present conception, accompanied by a belief of reality. I think, by far the wisest thing we can do is to accept the inexplicable fact, without any theory of how it takes place; and when we are obliged to speak of it in terms which assume a theory, to use them with a reservation as to their meaning⁸.'

Memory an ultimate fact! It is the first that stares us in the face on beginning to philosophise, and it haunts us through all our subsequent speculations. It is the 'dweller on the threshold' of philosophy, which unless we overcome will overcome us, and frustrate our magic.

The passage quoted does not show Mill's usual candour and consistency. His philosophy has broken down on an essential point, and he is reluctant to admit it. He tries to throw the blame on other things, and recommends that those who think with him should maintain a discreet silence on the subject of memory, or if obliged to speak of it do so in ambiguous language. That is hardly honest, and is bad philosophical practice. What we know or think we know we may leave alone—it will not run away; it is what we are conscious of not knowing that should receive our persistent attention.

Materialism presents at first sight the data out of which to construct a theory of memory, for it recognises the dependent character of consciousness and takes body to be its substance. Does the body show any marks or traces of thought that may serve to revive ideas in the absence of objects? None have yet been discovered. Nerves are used in objective observation, but they do not appear to be essential either to recollection in general or to any of the more elaborate forms of internal thought. The brain is used only when giving expression to thought.

Memory is noticed by everyone, even the least metaphysical. Persons who are incapable of understanding the difference between object and subject or general and particular, are yet perfectly well aware of the difference between remembering and forgetting. The phrases relating to this distinction are the commonest in every language. Memory is conspicuous—notorious—palpable. It is the pivot on which the whole mental system revolves. It cannot be gainsaid or ignored. There is no profit in boycotting it in the manner recommended by Mill—it must be faced and explained. 'How do you account for memory?' should be the first question addressed to one who pretends to have a science of mind. If he has no plausible answer to give, his system is not worth discussion. A philosophy without a theory of memory is like an astronomy without gravitation.

X—MEMORY OF SENTIMENTS

Sentiments are remembered and recollected like objects. For instance, a boy is punished for doing wrong and has pain; he does wrong again and is haunted with the fear of being punished again, which is the recollected and anticipated pain. We have thus two species of sentiment corresponding exactly to object and idea. The word 'feeling' is appropriate to the first, 'emotion' to the second. 'Passion' is a strong degree of either.

Objects that are associated with feelings are better remembered than those that merely affect the intellect, for there is a double memory at work—one in the core and one on the surface of our mind.

Sentiments are not susceptible of the same degree of analysis as objects. The inner matrix is more fluid and does not keep details. Apart from the objects associated with feelings, there is not much opportunity or need for classifying them. We are happy, wretched, or indifferent—that sums up the sentimental experience.

No two moral philosophers give the same list of sentiments. Some are satisfied with two—pain and pleasure. Spinoza gives a list of forty-seven⁹ sentiments, which includes luxury and drunkenness. It is evident that luxury is a general term which covers many different forms of feeling, and if the feeling of intoxication by alcohol is worth mentioning, so also must be the intoxications by opium and tobacco; and if these are included we must admit the feeling of nausea, which brings us to the sentiments associated with all diseased conditions of body or mind. Such distinctions are superfluous, for if the sentiment is purely personal and not associated with an external object, it is not of any general interest; if associated with an object and common to many persons it is best defined by reference to the object—as the pleasure of smelling a rose.

We have sometimes feelings of elation and depression for which we cannot find an internal reason nor yet an objective sign. Many of the so-called religious experiences are of this sort. So also are the sudden sympathies and aversions we feel towards certain people and places. Here there is an object, but we cannot find anything in the object that can be taken as specially significant of the feeling. We are said not to be able to 'analyse' our feeling, that is, assign it an object as cause.

These abnormal feelings may be explained by supposing that some external influences succeed in reaching our sentiment without exciting our intellect. Considering that intellect is artificial and may be very imperfect, and also that its efficiency depends to some extent on its being less sensitive than the original mental nature, it is reasonable to conclude that subtle emanations from our surroundings may occasionally affect us without exciting the intellectual consciousness. Panic, inspiration, mesmerism, and other 'occult' influences are probably due to this cause. If we further assume that sentiments so excited may then, by association, excite appropriate ideas in the intellect of the recipient, we have a likely explanation of what is called 'thought-transference.' Since ideas excite emotions, it is reasonable to suppose that feelings may excite ideas, or even the illusion that objects are being perceived.

XI—COMPARISON

Most ideas, except the particular (which are copies of single objects), are associated with a consciousness of resemblance and difference which arises in the following manner.

When new experience simply revives the imprint of a former experience we call it the same object or objects, though it is not numerically the same, being different at least in time. If a totally new imprint is made in the mind the experience is quite novel or strange, but we do not call it different.

Experience is usually neither quite the same as before nor quite strange, which means that the present noumenon has partially revived an old imprint and made a partially new one.

In this case we have a quadruple consciousness. There is first the present object; next the recollection of the object originally associated with the same imprint; thirdly, a consciousness of resemblance between the new and the old (the present object and the recollected idea) in so far as the imprints coincide, and (fourthly) a sense of difference in so far as they disagree. The limitation of resemblance gives rise to the sense of difference—a negative consciousness—and the shock of difference emphasises the resemblance. This is Comparison, the common basis of Generalisation and Imagination.
