The reaction against Aristotelianism had, as one of its results, a renascence of the atomic theory of Democritus and Lucretius; and one of the earliest adherents of the renovated doctrine was Bruno. Although a complete presentation of the theory was not given until his later works, the _De Minimo_ and the _Articuli adv. Mathematicos_, appeared, yet already in the Italian dialogues there were frequent references to it. In the _Cena_,[381] for example, it is said that in the physical division of a finite body infinite progress is impossible, and, as we shall afterwards find, in Bruno there is no distinction between physical and mathematical division. Again, in the _Cena_ an animistic atomism is suggested, which presents a curious anticipation of some of Leibniz' characteristic views. "It is more than probable, as all things partake of life, that many or innumerable individuals live not only in us, but in all composite things; when anything "dies," as is said, we must believe it to be not death, but change only; the accidental composition or concord ceases, the things that enter into it remaining always immortal; and this is truer of those things we call spiritual than of those we call corporeal or material."[382] Thus every body or organism, for all bodies are organisms to Bruno, is itself constituted by other living beings, the atoms--living atoms--being alike the origin and the end of all. So Leibniz wrote:--"Every living body has a presiding entelechy, which is the soul in the animal; but the members of this living body are full of other living beings--plants, animals,--each of which, again, has its entelechy or presiding soul."[383] In the _Infinito_ Bruno refers to the continuous changes of all composite bodies as arising from the ceaseless flux of atoms out of and into each body, even the greater "animals," the stars and planets, sending out particles, which wander through the universe from one to another.[384] Again, when discussing the four elements, he ascribes to water the power of holding together the atoms of earth, or "the dry." "If from the earth all water were to be removed, so that there remained purely dry matter, this remainder would necessarily be an incoherent, rare, loose substance, easy to be dispersed through the air, in the form of innumerable discontinuous bodies; for while the air or ether makes a continuum, that which makes a _coherent_ continuum is water or moisture."[385] These indivisible "prime bodies," of which the worlds are originally composed, are spoken of as flying throughout space from world to world, in infinite movement, entering now into this, now into that "composition."[386] Finally, in the _Spaccio_, we are reminded that "every trifle, however worthless, is of value in the order of the whole, the universe, for great things are composed of little, little things of the least, and these of the individuals (or indivisibles) or minima."[387] In its main outlines, accordingly, Bruno's atomic
