(3) Finally, there is the magic influence ascribed to certain words. It is the triumph of the theory of nomina numina; we need not return to it. But the working of the mind on words, erecting them into entities, conferring life and power on them—in a word, the activity that creates myths and is the final basis of all constructive imagination—appears also here.[122]
II
Up to this point we have considered the practical imagination only in its somewhat petty aspect in small inventions or as semi-morbid in superstitious fancies. We now come to its higher form, mechanical invention.
This subject has not been studied by psychologists. Not that they have misunderstood its rôle, which is, after all, very evident; but they limit themselves to speak of it cursorily, without emphasizing it.
In order to appreciate its importance, I see no other way than to put ourselves face to face with the works that it has produced, to question the history of discovery and useful arts, to profit by the disclosures of inventors and their biographers.
Of a work of this kind, which would be very long because the materials are scattered, we can give here only a rough sketch, merely to take therefrom what is of interest for psychology and what teaches us in regard to the characters peculiar to this type of imagination.
The erroneous view that opposes imagination to the useful, and claims that they are mutually exclusive, is so widespread and so persistent, that we shall seem to many to be expressing a paradox when we say that if we could strike the balance of the imagination that man has spent and made permanent in esthetic life on the one hand, and in technical and mechanical invention on the other, the balance would be in favor of the latter. This assertion, however, will not seem paradoxical to those who have considered the question. Why, then, the view above mentioned? Why are people inclined to believe that our present subject, if not entirely foreign to the imagination, is only an impoverished form of it? I account for it by the following reasons:
Esthetic imagination, when fully complete, is simply fixed, i.e., remains a fictitious matter recognized as such. It has a frankly subjective, personal character, arbitrary in its choice of means. A work of art—a poem, a novel, a drama, an opera, a picture, a statue—might have been otherwise than it is. It is possible to modify the general plan, to add or reduce an episode, to change an ending. The novelist who in the course of his work changes his characters; the dramatic author who, in deference to public sentiment, substitutes a happy denoûement in place of a catastrophe, furnish naïve testimony of this freedom of imagination. Moreover, artistic creation, expressing itself in words, sounds, lines, forms, colors, is cast in a mould that allows it only a feeble "material" reality.
The mechanical imagination is objective—it must be embodied, take on a form that gives it a place side by side with products of nature. It is arbitrary neither in its choice nor in its means; it is not a free creature having its end in itself. In order to succeed, it is subjected to rigorous physical conditions, to a determinism. It is at this cost that it becomes a reality, and as we instinctively establish an antithesis between the imaginary and the real, it seems that mechanical invention is outside the realm of the imagination. Moreover, it requires the constant intervention of calculation, of reasoning, and lastly, of a manual operation of supreme importance. We may say without exaggerating that the success of many mechanical creations depends on the skillful manipulation of materials. But this last moment, because it is decisive, should not make us forget its antecedents, especially the initial moment, which is, for psychology, similar to all other instances of invention, when the idea arises, tending to become objective.
Otherwise, the differences here pointed out between the two forms of imagination—esthetic and mechanical—are but relative. The former is not independent of technical apprenticeship, often of long duration (e.g., in music, sculpture, painting). As for the latter, we should not exaggerate its determinism. Often the same end can be reached by different inventions—by means differently imagined, through different mental constructions; and it follows that, after all allowances are made, these differently realized imaginations are equally useful.
