the Mutakallemim had no purpose in agreeing upon this proposition, or as most of the later adherents of that school affirm, that the first Mutakallemim had no ulterior object in endeavouring to prove the existence of atoms. On the contrary, every proposition here mentioned is indispensable; if one of these be rejected, the whole theory falls to the ground. The last-mentioned proposition is of particular importance; for when our senses perceive things by which any of the foregoing propositions are confuted, the Mutakallemim say that no notice should be taken of the perception of the senses so long as the proposition is supported by the testimony of the intellect, and established (as they believe) by proof. Thus they say that the continuous motion is interrupted by moments of rest; that the millstone in its motion is broken into atoms; that the white colour of a garment ceases to exist, and another whiteness comes in its stead. All these theories are contrary to what the eye perceives, and many inferences are drawn from the assumed existence of a vacuum, all of which are contradicted by the senses. The Mutakallemim, however, meet these objections by saying, whenever they can do so, that the perception of these things is withheld from the senses: in other instances they maintain that the contradiction has its source in the deceptive character of the senses. You know that this theory is very ancient, and was the pride of the sophists, who asserted that they themselves were its authors; this is stated by Galenus in his treatise on natural forces; and you know well what he says of those who will not admit the evidence of the senses.
Having discussed these propositions, I now proceed to explain the theory of the Mutakallemim concerning the above-mentioned four problems.
CHAPTER LXXIV
IN this chapter will be given an outline of the proofs by which the Mutakallemim attempt to demonstrate that the universe is not eternal. You must of course not expect that I shall quote their lengthy arguments verbatim: I only intend to give an abstract of each proof, to show in what way it helps to establish the theory of the creatio ex nihilo or to confute the eternity of the universe, and briefly to notice the propositions they employed in support of their theory. If you were to read their well-known and voluminous writings, you would not discover any arguments with which they support their view left unnoticed in the present outline, but you might find there greater copiousness of words combined with more grace and elegance of style; frequently they employ rhyme, rhythm, and poetical diction, and sometimes mysterious phrases which perhaps are intended to startle persons listening to their discourses, and to deter those who might otherwise criticize them. You would also find many repetitions; questions propounded and, as they believe, answered, and frequent attacks on those who differ from their opinions.
The First Argument.
Some of the Mutakallemim thought that by proving the creation of one thing, they demonstrated the creatio ex nihilo in reference to the entire universe. E.g., Zaid, who from a small molecule had gradually been brought to
