We speak of imagination as a complex mental operation, because it implies, in particular, the exercise of the power of association in furnishing those conceptions which are combined together; also the exercise of the power of relative suggestion, by means of which the combination is effected.

◊ 207. Process of the mind in the creations of the imagination.

It may assist us in more fully understanding the nature of imagination, if we endeavour to examine the intellectual operations of one who makes a formal effort at writing, whether the production he has in view be poetical or of some other kind.-A person cannot ordinarily be supposed to sit down to write on any occasion whatever, whether it involve a higher or lesser degree of the exercise of the imagination, without having some general idea of the subject to be written upon already in the mind. The general idea, or the subject in its outlines, must be supposed to be already present. He accordingly commences the task before him with the expectation and the desire of developing the subject more or less fully, of giving to it not only a greater continuity and a better arrangement, but an increased interest in every respect. As he feels interested in the topic which he proposes to write upon, he can, of course, by a mere act of the will, although he might not have been able in the first instance to have originated it by such an act, detain it before him for a length of time.

Various conceptions continue, in the mean while, to arise in the mind, on the common principles of association; but, as the general outline of the subject remains fixed, they all have a greater or less relation to it. And partaking in some measure of the permanency of the outline to which they have relation, the writer has an opportunity to approve some and to reject others, according as they impress him as being suitable or unsuitable to the nature of the subject. Those which affect him with emotions of pleasure, on account of their perceived fitness for the subject, are retained and committed to writing; while others, which do not thus affect and interest him, soon fade away altogether.—Whoever carefully no

tices the operations of his own mind, when he makes an effort at composition, will probably be well satisfied that this account of the intellectual process is very near the truth.

§ 208. Further remarks on the same subject.

The process, therefore, stated in the most simple and concise terms, is as follows. We first think of some subject. With the original thought or design of the subject, there is a coexistent desire to investigate it, to adorn it, to present it to the examination of others. The effect of this desire, followed and aided as it naturally is at such times by an act of the will, is to keep the general subject in mind; and, as the natural consequence of the exercise of association, various conceptions arise, in some way or other related to the general subject. Of some of these conceptions we approve in consequence of their perceived fitness to the end in view, while we reject others on account of the absence of this requisite quality of agreeableness or fitness.

For the sake of convenience and brevity we give the name of IMAGINATION to this complex state or series of states of the mind. It is important to possess a single term expressive of the complex intellectual process; otherwise, as we so frequently have occasion to refer to it in common conversation, we should be subjected, if not properly to a circumlocution, at least to an unnecessary multiplication of words. But while we find it so much for our convenience to make use of this term, we should be careful and not impose upon ourselves, by ever remembering that it is the name, nevertheless, not of an original and independent faculty, which of itself accomplishes all that has been mentioned, but of a complex or combined action of a number of faculties.

209. Illustration from the writings of Dr. Reid.

Dr. Reid (Essay iv., ch. iv.) gives the following graphical statement of the selection which is made by the writer from the variety of his constantly arising and departing conceptions.-"We seem to treat the thoughts, that present themselves to the fancy in crowds, as a great man

treats those [courtiers] that attend his levee. They are all ambitious of his attention. He goes round the circle, bestowing a bow upon one, a smile upon another, asks a short question of a third, while a fourth is honoured with a particular conference; and the greater part have no particular mark of attention, but go as they came. It is true, he can give no mark of his attention to those who were not there; but he has a sufficient number for making a choice and distinction."

210. Grounds of the preference of one conception to another.

A question after all arises, On what principle is the mind enabled to ascertain that congruity or incongruity, fitness or unfitness, agreeably to which it makes the selec tion from its various conceptions? The fact is admitted, that the intellectual principle is successively in a series of different states, or, in other words, that there are successive conceptions or images, but the inquiry still remains, Why is one image in the group thought or known to be more worthy than any other image, or why are any two images combined together in preference to any two others?

The answer is, it is owing to no secondary law, but to an instantaneous and original suggestion of fitness or unfitness. Those conceptions which, by means of this original power of perceiving the relations of things, are found to be suitable to the general outlines of the subject, are detained. Those images which are perceived to possess a peculiar congruity and fitness for each other, are united together, forming new and more beautiful compounds. While others, although no directly voluntary power appears to be exercised over either class, are neglected and soon become extinct. But no account of this vivid feeling of approval or disapproval, of this very rapid perception of the mutual congruity of the images for each other or for the general conception of the subject, can be given, other than this, that with such a power the original author of our intellectual susceptibilities has been pleased to form us. This is our nature; here we find one of the elements of our intellectual efficiency; without it we might still be intellectual beings, but it would be with the loss both of the reasoning power and of the imagination.

$211. Illustration of the subject from Milton.

What has been said can perhaps be made plainer, by considering in what way Milton must have proceeded in forming his happy description of the Garden of Eden. He had formed, in the first place, some general outlines of the subject; and as it was one which greatly interested his feelings, the interest which was felt tended to keep the outlines steadily before him. If the feeling of interest was not sufficient to keep the general subject before the mind, he could hardly fail to detain it there by adding the influence of a direct and decisive act of the will. Then the principles of association, which are ever at work, brought up a great variety of conceptions, having a relation of some kind to those general features; such as conceptions of rocks, and woods, and rivers, and green leaves, and golden fruit.

The next step was the exercise of that power which we have of perceiving relations, which we sometimes denominate the Judgment, but more appropriately the susceptibility or power of Relative Suggestion. By means of this he was at once able to determine, whether the conceptions which were suggested were suitable to the general design of the description and to each other, and whether they would have, when combined together to form one picture, a pleasing effect. Accordingly, those which were judged most suitable were combined together as parts of the imaginary creation, and were detained and fixed by means of that feeling of interest and those acts of the will which were at first exercised towards the more prominent outlines merely; while others speedily disappeared from the mind. And thus arose an imaginary landscape, glowing with a greater variety and richness of beauty, more interesting and perfect, in every respect, than we can ever expect to find realized in nature.

212. The creations of imagination not entirely voluntary. From the explanation which has been given of the operations of the power under consideration, it will be seen that, in its action, it is subject to limitations and restrictions. The opinion, that even persons of the most ready and fruitful imagination can form new imaginary creations

whenever they choose, by a mere volition, however widely it may have prevailed, does not appear to be well founded. In accordance with what may be regarded as the common opinion, we will suppose, as an illustration of what we mean, that a person wills to imagine a sea of melted brass, or an immense body of liquid matter which has that appearance. The very expressions, it will be noticed, are nugatory and without meaning, since the sea of brass which the person wills to conceive of or imagine, is, by the very terms of the proposition, already present to his thoughts. Whatever a person wills, or, rather, professes to will to imagine, he has, in fact, already imagined; and, consequently, there can be no such thing as imaginations which are exclusively the result of a direct act of the will. So that the powers of invention, although the influence of the indirect and subordinate action of the will may be considerable, must be aroused and quickened to their highest efforts in some other way.

And this view admits of some practical applications. Men of the greatest minds (great, we mean, in the walks of literature) are kept in check by the principles which are involved in the exercise of imagination. Genius, whatever capabilities we may attribute to it, has its laws. And it is true, in regard to every standard work of the imagination, that it is the result, not of an arbitrary and unexplainable exercise of that power, but of a multitude of circumstances, prompting and regulating its action; such as the situation in life, early education, domestic habits, associates, reading, scenery, religion, and the influence of local superstitions and traditionary incidents. These are like the rain and sunshine to the earth, without which it necessarily remains in its original barrenness, giving no signs of vivification and beauty. In the matter of creative power, Bunyan will bear a comparison, undoubtedly, with Walter Scott; but Scott, in the situation in which he was placed, and with the habits of thought and feeling which he cherished, could not have written the Pilgrim's Progress; nor could Bunyan, on the other hand, have written the Heart of Mid Lothian; not because either of them was destitute of the requisite degree of imagination, but because the creations of the imagina
