Giordano Bruno

by J. Lewis McIntyre

From the principle of the identity of nature it follows that bodies which are remote from us are the same in kind with those that are with us and near us; nothing may be denied of the former which is affirmed of the latter, and vice versa. There can be no doubt, therefore, of their similar composition and similar parts. Thus if here on the earth we nowhere see fire subsisting without earth, nowhere earth without water or fire, while their composites are both contained in and penetrated by air and void, then the same is necessarily the case in the upper world also; neither sense nor reason compels us to assert or suspect otherwise.[369] Bruno has grasped, however confusedly, the idea that each individual, each being in the universe, is as it were an epitome of the universe itself; that each therefore stands in a peculiar relation to it, differing from it only in the “proportion” in which the elements are composed into unity. It is impossible not to see in this idea the germ of the most important development of Leibniz’ philosophy, whatever the source may have been through which it came to the latter. It is true that here, at least, Bruno’s conception appears much less spiritual than that of his successor, inasmuch as he is thinking rather of the actual physical elements which go to make up a body (and in which all bodies are similar to one another). On the other hand, the formation of the body is, in his view, the work of the soul, and it is in the last resort the identity of the universal soul of nature in all its members that brings each of these into correspondence with all others. It is true, also, that Bruno has no definite explanation of what constitutes an individual, and his readers are exposed to the dilemma either of regarding the physical atoms as themselves “beseelt,”—a view which Bruno nowhere sanctions,—or, on the other hand, of accepting a dualism of spirit (the soul of the universe or God) and matter (the material atoms, moisture, fire, and ether). Yet the tenour of Bruno’s philosophy is wholly opposed to such a dualism. As a corollary of this theory, Bruno suggested an explanation of what has been called “spontaneous generation,” supported, however, by tales of the credulous rather than by actual observation. “Dust that has been heated by the sun, as soon as moisture falls upon it, becomes a frog, the whole substance of dung goes into worms or flies, the body of a horse will turn into wasps, the provident bee rises from the body of an ox!”[370] As each thing is in its inner nature identical with every other, so it may, and in the natural course does, become every other, as we have learned from the Italian works. Nevertheless, the outward appearances of things do not cease to be different from one another. “That is more latent in one subject which is more unfolded in the remainder.” “The subject of all is one (monas), and all things are in truth one, although in individuals they seem to be many.”

Movements of bodies; their soul-principle.The movements of the earth and of other free-moving bodies are always attributed by Bruno to an “internal principle or soul.” Movement from without could only take place through direct contact, and the liquid air or ether is too light to move these heavy bodies.[371] “It is taking things by the wrong end to say that the loadstone attracts the iron, the amber the straw, the sun the sunflower. In the iron there is a kind of sense, awakened by a spiritual (i.e. a subtly material) virtue diffused from the loadstone, ... and generally everything that desires and has intelligence moves towards the thing desired, converts itself into it as far as possible, beginning with the wish to be in the same place.” By the same principle are explained the phenomena of gravity, which is defined as impulse towards the place of preservation, such as the earth is to the stone that has formed part of it; its opposite, “levity,” is impulse away from the contrary or the injurious. “Gravity and levity are nothing but the impulse of parts to their place, where they may either move or be at rest, or to a place through which it is necessary for them to go (in the circular movement of all material things).” Thus the motions of the heavy and the light are merely relative movements; the same kind of motion does not belong always to the same kind of substance or element.[372]

The movement of the stars is determined not by considerations of place only, but also by the necessity that bodies of one kind are under of deriving sustenance from those of another,—the suns from the earths and the earths from the suns. It is through the soul that their needs are felt, and the soul directs their movements as does the human soul those of the human body. There are, however, no fixed limits to their movements: they are governed only by the convenience of life, as perceived by the sense and mind, which are inborn in each. By this fantastic principle Bruno explained what he thought to be the fact, that all heavenly bodies whatsoever are in movement; or perhaps we should say he inferred the fact from the principle:—which was first in the order of his thought it would be impossible to know. Like most of his contemporaries he looked upon the conception of a soul in all things with peculiar reverence—

Porgimus haec paucis, vulgus procul esto prophanum,

Ne liceat laico sacrum conscendere montem.

The method by which Bruno sought to know the nature of the souls of the worlds is one which the course of modern philosophy has rendered familiar to us in other connections. It rests upon the argument from the part to the whole. “Whatever we find in a part of the world belongs, in a higher sense (sublimius), to the whole, and must be attributed to it. All the capacities of each part are attributed to the whole—that is, their perfections and activities, not the qualities they possess as parts, and as less than the whole in any respect.” Thus the hindrances to which lesser individuals are exposed, the necessity of taking in and giving out matter as their forms change, exist in the greater individual in a minimal degree. But in all parts of the earth Bruno found signs of life, sensation, and even intelligence. Stones of different kinds were universally believed to have a kind of sensibility and instinct: to move of their own accord, attract other bodies to themselves, act upon our human spirits and senses. The phenomena of animal instinct were a constant object of interest to Bruno, who saw in them the expression of a deeper intelligence than the merely human. It is true the observations on which he built may not always have been exact; but that does not detract from the value of his principle. Thus the porcupine (istrix) moved his admiration because of its careful storing up of a stock of darts in its back, with which to protect its life; it could, with unerring aim, cast one at its enemy, hearing, it is said, with its skin; and its precision far surpassed all that the cunning of man, with his many instruments, could do. With perfect skill it threw its darts, yet sparingly, so that no part of its body was ever defenceless, the spirit directing all its actions from one centre, to which, from every part of the body, report was made! “With how much higher reason will the star be endowed, of the body of which animals are made, by whose spirit they flourish? So the earth from one centre directs all its actions and those of its parts; it never errs, neither it nor any of the worlds which dwell in the immeasurable ether.”[373]

Bruno rejected[374] the popular notion that the behaviour of ants, spiders, and other animals does not spring from their proper foresight and artifice, but from divine, unerring intelligence acting upon them from without, giving them those “thrusts” (spinte) which are called “natural instincts”—a term which he regarded as meaningless. “Is this ‘natural instinct’ sense or intellect? If the former, is it internal or external? Clearly it is not external; but if internal, where is the internal sense from which they could have their foresight, their arts and artifices, their precautions, expeditions, to meet various conditions, both present and future? There must be some proximate principle, i.e. a form of intelligence peculiar to each animal, which determines its actions. The divine and universal intelligence is merely the principle that gives it intelligence, through which it understands.”[375] The action of animals of a given kind were supposed to be after one perfect model, and to be undeliberate. Bruno therefore placed their intelligence higher than that of man, nearer the level of that of the world-souls. “The swallow makes its nest, the ants their cave, the spiders their web or nets, in one way only, than which they could not make them more admirably or suitably.... Who knows whether the spirit of man is rising upwards, that of others moving downwards? At least it is to be referred to a defect of light and divine force that men hesitate and deliberate in all that belongs to the means of life, the modes of worship and defence, for if all knew perfectly, all would be governed in the best, and consequently in one way only.” It is, then, on the analogy of these supposed higher, unerring faculties of animals that Bruno considers the souls of the worlds to think and act. They have perfect freedom, since their life and soul are their own, not borrowed, as ours. “Thus as we breathe, see, sleep, without labour or anxiety, and while our soul performs the function of life, the vital humours and spirits continually circulate, so these, the chief members of the world, divine animals, have no need to undergo any anxious toil, for all things with them are done for the best.” Their fixed aim of life defines for them certain determinate orbits, “in which they move freely by the force of that soul which is much more certainly present in these high, perfect, divine bodies than in us, of more ignoble condition, who draw from them spirit and body, come forth living out of their bosom, are nourished by them, and at length are dissolved and received back into them.”[376]

It is to the internal spirit also that the spherical form of the worlds is due. The so-called mountains of the earth do not in the least detract from its spherical form. Bruno anticipated modern science in his discovery or intuition that the real mountains are not those we are accustomed to call such, but immense tracts of country,—the whole of France, for example. “I find the whole country of France to be one mountain, which rises gradually from the North Sea to Auvergne, where is its summit, marked on the west by the Pyrenees, where the Garonne flows, on the east by the Rhone, on the south by the Mediterranean Sea.”[377] The whole earth is, however, as smooth in reality as is to us the pumice stone, which to the ant seems furrowed with mountains and valleys. It is on teleological grounds that Bruno accounts for this sphericity. Composite things are preserved through the harmony and union of their parts, while decay arises from dissolution. But such harmony and union are best secured by the spherical form: towards this form, then, every soul aspires in the moulding of its body. The most perfect animals, the stars, having fewer limitations, have the greater advantages; being almost independent, free, self-sufficient, they are most closely united in themselves, i.e. tend most nearly to the purely spherical form.[378]

However perfect they are, the stars are yet of mortal stuff. “You may say if you will that the worlds change and decay in old age, or that the earth seems to grow grey with years, and that all the great animals of the universe perish like the small, for they change, decay, dissolve. Matter, weary of old forms, eagerly snatches after new, for it desires to become all things, and to resemble, as far as may be, all being.” The efflux and influx of atomic matter into the great bodies is continuous, and this is the only kind of motion which is unceasing.[379] “As the conflux of native matter is greater, so the bodies grow more and more, and increase up to a certain limit, on touching which they grow weary and become subject to a contrary order; as about the seed atoms are gathered and added continuously until the body and its limbs reach their maturity, when the same parts are cast out from the centre, and the breaking up of the composite is presented to our eyes.” Hence there are atoms innumerable roaming through the void, while infinite changes succeed one another in bodies. Those in one region receive the atoms repulsed from another: there is no danger of their straying infinitely without reaching a goal, for everywhere are great bodies to receive what is expelled from other stars.

Composite as the worlds are,—capable, therefore, of dissolution and destruction,—yet, as Timaeus had suggested, the power and providence of the divine purpose may maintain them eternally as they are.
