Giordano Bruno

by J. Lewis McIntyre

The two kinds of matter, or potentiality, the lower and the higher, are thus essentially one; so we reach the notion, not indeed of “the highest and best principle,” as Bruno is again careful to remind us, but of the soul of the world, as reality of all, and potency of all, and all in all. Thus in the end, although individuals are innumerable, all things are one; and the knowledge of this unity is the goal and limit of all philosophy of nature.

The unity of spirit and body.This unity, which embraces all the knowable, is the subject of the fifth dialogue of the Causa. The steps by which we have reached it are:—first, the identification of a common nature, or substratum in things corporeal,—corporeal matter, that which is common to all physical existences; secondly, the recognition that there must similarly be a corresponding matter, or common ground of things spiritual; there also differences exist and demand an identity; and finally, corporeal matter and spiritual matter must themselves coincide in ground; there must exist that which is indifferently either, or which is the potency of both, and their “subject” or substratum. To the objection that to have dimensions is characteristic of matter, it is answered that each kind of matter has dimensions, only the latter has them absolutely, i.e. it has all indifferently, and therefore none, while the other is always “contracted” to one or other at each instant, but has all successively. We have seen that at the close of the fourth dialogue Bruno refers again to the first principle, unknowable, or knowable only by faith, and professes to abstain from any consideration of it. It is quite clear, however, that Bruno could not have said of it anything other than he says of this unity of the corporeal and the spiritual itself. That which is implicitly all reality in such a manner that it is at the same time none of the particular forms of the real, is all things and none—could not be other than the highest principle. Further, this unity already has the distinction applied formerly to the Highest Intelligence,—it “is all,” and at the same time it “creates all,” in producing the forms out of itself. The unity then is only the world-soul from a special point of view, or the world-soul is at once the unity of itself and of the corporeal world.[280] This means that of the spiritual and the corporeal worlds each is a unity in itself, and each only a special aspect of a final unity which embraces both. It is no wonder then that Schelling found a congenial spirit in Bruno. The reality of this final matter or unity is moreover higher, truer, than that of any of the forms to which it gives birth, and finally it is divine. Little more is wanting to prove the entire superfluity of the theological highest principle. The unity (or matter) is by no means an “abstract” identity, but a concrete whole, which contains all differentiation in itself, and a “dynamic” being, which produces, or realises, its own modes. “Determinate, sensible, explicate existence is not the highest characteristic (raggione) of actuality, but is a thing consequent, an effect of the latter; thus the principal essence of wood, e.g. the characteristic of its actuality, does not consist in its being ‘bed’; but in its being of such a substance and consistency that it may be bed, bench, beam, idol, or anything formed of wood. Nature, however, from its material produces all things, not as art, by mechanical removal or addition of parts, but by separation, birth, efflux, as the Pythagoreans understood,”—Bruno adds Anaxagoras, Democritus, the Wise Men of Babylon, Moses! “Rather, then, it contains the forms and includes them, than is empty of them, or excludes them; and matter, which makes explicit what it contains implicitly, ought to be called a Divine thing: it is the substance of nature.”[281] Coincidence of all things in the One.Thus the One is the only ultimate reality; it is neither matter nor form, yet both together,—implicitly. And it has no parts, or all parts, for all parts coincide in it, the smallest with the greatest, in it all particular things coincide with one another, and all differences. It has all possible existence and is therefore unchangeable, it has all perfections and therefore is infinitely perfect.

“The universe is one, infinite, immovable. One is the absolute possibility, one the reality. One the form or soul, one matter or body. One the thing, one the ens. One the greatest and best, which can not be comprised, and therefore can neither be ended nor limited, and even so is infinite and unlimited, and consequently immovable. It does not move locally, for there is no place outside of itself, to which it might transport itself (for it is the all). Of it is no generation, for there is no other existence which it can desire or expect, for it has all existence. Of it is no corruption, for there is no other thing to which it can change; it is everything. It cannot grow less or greater, for it is infinite; it cannot be added to, and it cannot be subtracted from, for the infinite has no proportional parts. It cannot be subject to mutation in any quality whatever, nor is there anything contrary to, or diverse from it, which may alter it, for in it all things are in harmony.”[282] In it height is not greater than length or depth; hence by a kind of simile it may be called a sphere. It has no parts, for a part of the infinite must be infinite, and if it is infinite it concurs in one with the whole; hence the universe is one, infinite, without parts. Within it there is not part greater and part less, for one part, however great, has no greater proportion to the infinite than another, however small; and therefore, in infinite duration, there is no difference between the hour and the day, between the day and the year, between the year and the century, between the century and the moment; for moments and hours are not more in number than centuries, and those bear no less proportion to eternity than these. Similarly, in the immeasurable, the foot is not different from the yard, the yard from the mile, for in proportion to immensity, the mile is not nearer than the foot. Infinite hours are not more than infinite centuries, infinite feet are not of greater number than infinite miles.[283] Indifference of all things in the Infinite.Thus, Bruno frankly draws the conclusion, which is inherent in all pantheistic thought, that in the infinite all things are indifferent; there are no proportional parts thereof—in it one is not greater nor better than another: “In comparison, similitude, union, identity with the infinite, one does not approach nearer by being a man than by being an ant, by being a star than by being a man. In the infinite these things are indifferent, and what I say of these holds of all other things or particular existences. Now if all these particular things in the infinite are not one and another, are not different, are not species, it necessarily follows that they are not number (i.e. not distinct)—the universe is again an immovable, unchangeable one. If in it act does not differ from potency, then point, line, superficies and body do not differ in it (for each is potency of the other—a line by motion may become a surface, a surface a body). In the infinite, then, point does not differ from body; since the point is potency of body, it does not differ from body, where potency and act are one and the same thing. If point does not differ from body, centre from circumference, finite from infinite, the greatest from the least, then the universe, as we have said, is all centre, or the centre of the universe is everywhere; or, again, the circumference is everywhere but the centre is nowhere.” Thus, not only are the particular existences indifferent in the infinite: they have also in it no true reality, i.e. their existence is a purely relative one.

We have now to consider the relation of particular things one to another. It follows from the argument that all things are in all; each particular thing has the possibility of all reality, has all reality implicit in itself, but only one mode is at any particular time realised, and the life of particular things consists in their constant transmutation from one mode to another. While the universe comprehends all existence and all modes of existence,—of particular things, each has all existence, but not all modes of existence, and cannot actually have all circumstances and accidents, for many forms are incompatible in the same subject, either as contraries or as belonging to diverse species. The same individual subject (supposito) cannot be under the accidents of horse and of man, under the dimensions of a plant and of an animal. Moreover, the universe comprehends all existence wholly, because outside of and beyond infinite existence there is nothing that exists, for there is no outside or beyond: of particular things on the other hand, each comprehends all existence, but not wholly, for beyond each are infinite others. But the ens, substance, essence of all is one, which being infinite and unlimited in its substance as in its duration, in its greatness as in its force, can neither be called principle nor resultant; for as everything concurs in its unity and identity, it is not relative, but absolute. In the one infinite, immovable, which is substance, ens, there is multitude, number; and number, as “mode” of the ens, differentiates thing from thing; it does not therefore make the ens to be more than one, but to be of many modes, forms, and figures. Hence “leaving the logicians to their vain imaginings,” we find that all that makes difference and number is pure accident, pure figure, pure “complexion”; every creation of whatsoever sort it may be is an alteration, the substance remaining always the same, for there is only One Being, divine, immortal.[284]

Beauty, harmony, permanence of nature.Thus all things are in the universe, the universe in all things; we in it, it in us; and so all concurs in a perfect unity. Therefore, cries Bruno, we need not be troubled in spirit, nor be afraid; for this unity is one, stable, and always abides; this one is eternal; every aspect, every face, every other thing, is vanity, is as nought; all that is outside of this One is nought. These philosophers have found the wisdom that they love, who have found this unity. Wisdom, truth, unity, are the same. All difference in bodies, difference of formation, complexion, figure, colour, or other property, is nothing but a varying aspect of one and the same substance,—an aspect that changes, moves, passes away, of one immovable, abiding, and eternal being, in which are all forms, figures, members, but indistinct and “agglomerated,” just as in the seed, or germ, the arm is not distinct from the head, the sinew from the bone, and the distinction or “disglomeration” does not produce another and new substance, but only realises in act and fulfilment certain qualities of the substance, already present.

The coincidence of Bruno’s doctrine with some of Spinoza’s principal positions is striking, although their terms are different. The indeterminate all-comprising unity of Bruno is that which was afterwards called by Spinoza substance; its two aspects, material and spiritual—substances with Bruno,—are attributes in Spinoza, and finally, the innumerable finite and passing modes with both are mere accidents, and therefore do not determine any change in the one reality itself. In a subsequent chapter other more detailed resemblances will be pointed out in their bearing on the history of Spinoza’s development.

Coincidence of Contraries.The concluding portion of this dialogue and of the work is taken up with the doctrine of the Coincidence of Contraries, which derives from that of the unity and coincidence of all differences, and which, although it was undoubtedly contained in his own system, Bruno obtained directly from Nicholas of Cusa. It is an indirect proof, from the side of particular things themselves, of the identity of all in the One. The first illustrations are geometrical.[285] “Signs.”The straight line and the circle, or the straight line and the curve, are opposites; but in their elements, or their minima, they coincide, for, as Cusanus saw, there is no difference between the smallest possible arc and the smallest possible chord. Again, in the maximum there is no difference between the infinite circle and the straight line; the greater a circle is, the more nearly it approximates to straightness ... as a line which is greater in magnitude than another approximates more nearly to straightness, so the greatest of all ought to be superlatively, more than all, straight, so that in the end the infinite straight line is an infinite circle. Thus the maximum and the minimum come together in one existence, as has already been proved, and both in the maximum and in the minimum, contraries are one and indifferent.

These geometrical illustrations are “signs” of the identity of contraries, those which follow are called by Bruno “verifications,”[286] the first of which is taken from the primary qualities of bodies. “Verifications.”The element of heat, its “principle,” must be indivisible—it cannot have differences within itself, and can be neither hot nor cold, therefore it is an identity of hot and cold. “One contrary is the ‘principle’ or starting-point of the other, and therefore transmutations are circular, because there is a substrate, principle, term, continuation and concurrence of both.” So minimal warmth and minimal cold are the same. The movement towards cold takes its beginning from the limit of greatest heat (its “principle” in another sense). Thus not only do the two maxima sometimes concur in resistance, the two minima in concordance, but even the maximum and the minimum concur through the succession of transmutations. Doctors fear when one is in the best of health; it is in the height of happiness that the foreseeing are most timid. So also the “principle” of corruption and of generation is one and the same. The end of decay is the beginning of generation; corruption is nothing but a generation, generation a corruption. Love is hate, hate is love in the end; hatred of the unfitting is love of the fitting, the love of this the hatred of that. In substance and in root, therefore, love and hate, friendship and strife, are one and the same thing. Poison gives its own antidote, and the greatest poisons are the best medicines. There is but one potency of two contraries, because contraries are apprehended by one and the same sense, therefore belong to the same subject or substrate; where the principle (i.e. the source, or faculty) of the knowledge of two objects is the same, the principle (i.e. elementary form) of their existence is also one. (Examples are the curved and the plane, the concave and the convex, anger and patience, pride and humility, miserliness and liberality). In conclusion:—“He who would know the greatest secrets of nature, let him regard and contemplate the minima and maxima of contraries and opposites. Profound magic it is to know how to extract the contrary after having found the point of union.” Aristotle was striving towards it, but did not attain it, said Bruno; “remaining with his foot in the genus of opposition, he was so fettered that he could not descend to the species of contrariety ... but wandered further from the goal at every step, as when he said that contraries could not co-exist at the same time in the same subject.”[287] There is a naïve but at the same time a bold realism in this demand of Bruno’s that reality shall correspond even to the simpler unities of thought—unities which after all are mere limitations. It is only because we cannot distinguish in imagination between an infinite circle and a straight line that their identity in actual existence is postulated, and so the minimal chord and minimal arc coincide to our limited imagination only. Admittedly in the case of sense-qualities the argument is from oneness of faculty knowing to oneness of things known. These, however, are only, as we have said, “signs” and “verifications” of a metaphysical truth which is arrived at by other methods.

A corresponding passage in the De Minimo[288] explains more fully the coincidence of contraries in the minimum:—“In the minimum, the simple, the monad, all opposites coincide, odd and even, many and few, finite and infinite; therefore that which is minimum is also maximum, and any degree between these.” Besides the coincidence of contraries in God as the monad of monads, the examples are given of the indifference of all dimensions in the universe, and the ubiquity of its centre; the indifference of the radial directions from the centre of a particular sphere; the indifference of all points in the diurnal rotation of the earth, so that any point whatever is east, west, north, or south; the “subjective” coincidence of concave and convex in the circle (“subjective” meaning “in the thing itself”); the coincidence of the acute and the obtuse angle in the inclination of one line to another; that of smallest arc and chord as of greatest arc and chord, “whence it follows that the infinite circle and the infinite straight line, also the infinite diameter, area, and centre are one and the same.” Lastly, we have the coincidence of swiftest motion with slowest, or with rest, “for the absolutely swift (swift ‘simpliciter,’ i.e. in its highest possible manifestation, without any degree of the contrary, slowness) which moves from A to B, and from B to A, is at once in A, and in B, and in the whole orbit, therefore, it stands still.”
