In like manner, if Anaxagoras or any other affirm that the mind is essential truth and wisdom, ¹ what call have I to debate with a man about a word? For it is manifest that mind gives being to the order and mode of all things, and that it may be suitably called infinite with respect not to its extension in space, but to its power, the range of which transcends all human thought. Nor [shall I dispute his assertion] that this essential wisdom is formless; for this is a property of material things, that whatever bodies are infinite are also formless. Cicero, however, from his desire to confute such opinions, as I suppose, in contending with adversaries who believed in nothing immaterial, denies that anything can be annexed to that which is infinite, because in things material there must be a boundary at the part to which anything is annexed. Therefore he says that Anaxagoras "did not see that motion joined to sensation and to it" (i.e. linked to it in unbroken connection) "is impossible in the infinite" (that is, in a substance which is infinite), as if treating of material substances, to which nothing can be joined except at their boundaries. Moreover, in the succeeding words--"and that sensation of which the whole system of nature is not sensible when struck is an impossibility" ² --Cicero speaks as if Anaxagoras had said that mind--to which he ascribed the power of ordering and fashioning all things--had sensation such as the soul has by means of the body. For it is manifest that the whole soul has sensation when it feels anything by means of the body; for whatever is perceived by sensation is not concealed from the whole soul. Now, Cicero's design in saying that the whole system of nature must be conscious of every sensation was, that he might, as it were, take from the philosopher that mind which he affirms to be infinite. For how does the whole of nature experience sensation if it be infinite? Bodily sensation begins at some point, and does not pervade the whole of any substance unless it be one in which it can reach an end; but this, of course, cannot be said of that which is infinite. Anaxagoras, however had not said anything about bodily sensation. The word "whole," moreover, is used differently when we speak of that which is immaterial, because it is understood to be without boundaries in space, so that it may be spoken of as a whole and at the same time as infinite--the former because of its completeness, the latter because of its not being limited by boundaries in space.
