 Another difference between the theory of atomism that Aristotle addressed and the one that Avicenna does is the very nature of the atoms themselves. Democritus’ atoms with their differences in shapes as well as differences in possible arrangement and positions are best considered as corpuscles, that is, small bodies. Thus when speaking of Democritus, we can speak of “corpuscular atomism.” Such is not necessarily the case with Epicurean minimal parts or Kalām atoms, which, while making up the parts of bodies, were not themselves considered bodies. While there is some dispute about this point concerning Epicurus, Kalām atomists are fairly consistent in saying that the sole property of their atoms is that they occupy space (mutaḥayyiz) but otherwise lack any other determinations. In fact, Kalām atoms might best be thought of as a matrix making up all space, with the individual atom representing the smallest spatial magnitude necessary for the occurrence of some co-incidental event, determination or accident, like being red or hot or wet or even possessing power. In this respect, Kalām atoms are comparable to the pixels on a modern-day TV or computer screen. The two are comparable in that both are the smallest relevant units in which a sensible effect occurs, whether some color for modern pixels or any accident more generally for Kalām atomists. Consequently, this variety of atomism might be called “pixelated atomism” to contrast it with the corpuscular atomism that had been the target of Aristotle’s criticisms. The significant point is that Avicenna could not simply appeal to Aristotle and his attack on corpuscular atomism when critiquing atomism as he found it.
