=180.= Although the ‘first cause’ and the ‘Word’ are thus formally identified, their associations in connexion with cosmogony are very different. For whereas the ‘Word’ suggests reason and purpose, and leads up to the dogma that the universe is governed by divine providence, the term ‘cause’ suggests the linking of cause and effect by an unending chain, the inevitable sequence of events which leaves no room for effort or hope. These terms therefore point to the supreme problems of Fate and divine Purpose, Determinism and Free-will, and as such will be discussed in a later chapter[42]. Here it is sufficient to note that the Stoics not only accept, but insist upon the use of terms suggesting both points of view, and look therefore beyond their immediate opposition to an ultimate reconciliation; and that the importance attached to the doctrine of a ‘single and general cause’ by no means excludes a multiplicity of individual causes depending upon it, and capable of classification according to their relative importance[43]. [Sidenote: The categories.] =181.= Thus the conception of ‘body,’ so simple to the plain man, becomes to the philosopher manifold and intricate. Its interpretation is to some extent brought into harmony with common speech through the doctrine of the ‘categories’ based upon Aristotle’s teaching[44]. But whereas Aristotle endeavoured in his categories to classify the various but independent classes of existences, the Stoics considered the different aspects in which the one primary body might be studied. The first two categories, those of ‘substance’ (ὑποκείμενον) and of ‘quality’ (ποιόν), agree with those of Aristotle[45], and clearly correspond to the grammatical categories of noun and adjective. The third category is that of ‘disposition’ (πὼς ἔχον), as ‘lying down’ or ‘standing[46].’ The fourth is that of ‘relative position’ (πρός τί πως ἔχον), as ‘right’ and ‘left,’ ‘son’ and ‘father[47].’ Some of the categories are further subdivided[48]; but enough is here stated to shew the object of the analysis, which in practice may have been useful in securing some completeness in the discussion of particular conceptions. Of ‘substances’ the Stoics, like others, say that they ‘exist,’ and are ‘bodies’; of qualities they boldly say the same[49]. But they do not consistently apply the same terms to disposition and relative position; in this direction they are at last led, like other philosophers, to speak of things which ‘do not exist.’ They could not take the modern view that all such discussions are verbal entanglements, of which no solution is possible, because they believed that there was a natural harmony between words and things. We on the other hand shall be little inclined to follow their analysis into its manifold details[50]. [Sidenote: Substance.]
