“As eternal, the existent also is unlimited, since it has no beginning from which it came, nor end in which it ceases. The infinite all is one, for, if there were two or more, they would limit one another,” and thus have a beginning and end. The one would be the nothing of the other and come forth from this nothing. “This one is like itself; for if it were unlike it would no longer be the one that was posited, but many. This one is likewise immovable, inasmuch as it does not move itself, since it does not pass out into anything. In passing out, it would require to do so into what is full or what is empty; it could not be into the full, for that is an impossibility, and just as little could it be into what is empty, for that is the nothing. The one, therefore, is in this way devoid of pain or suffering, not changing in position or form, or mingling with what is different. For all these determinations involve the origination of non-being and passing away of Being, which is impossible.” Thus here again the contradiction which takes place when origination and passing away are spoken of, is revealed. Now Melissus places opinion in opposition to this truth. The change and multiplicity extinguished in Being appears on the other side, in consciousness, as in what is opinionative; it is necessary to say this if only the negative side, the removal of these moments, the Absolute as destitute of predicate, is laid hold of. “In sensuous perception the opposite is present for us; that is to say, a number of things, their change, their origination and passing away, and their intermingling. Thus that first knowledge must take its place beside this second, which has as much certainty for ordinary consciousness as the first.” Melissus does not seem to have decided for the one or the other, but, oscillating between both, to have limited the knowledge of the truth to the statement that, speaking generally, between two opposite modes of presentation, the more probable opinion is to be preferred, but that what is so preferred is only to be regarded as the stronger opinion, and not as truth. This is what Aristotle says of him.
