Book 9
2.117
There are some points, it is true, which are beyond the power of art to inculcate. For example if the case, tense or mood with which we have begun, produces a harsh rhythm, it must be changed. But is it possible to lay down any definite rule as to what the change of case, tense or mood should be? It is often possible to help out the rhythm when it is in difficulties by introducing variety through the agency of a figure. But what is this figure to be? A figure of speech or a figure of thought? Can we give any general ruling on the subject? In such cases opportunism is our only salvation, and we must be guided by consideration of the special circumstances.
2.118
Further with regard to the time-lengths, which are of such importance where rhythm is concerned, what standard is there by which they can be regulated save that of the ear? Why do some sentences produce a full rhythmical effect, although the words which they contain are few, whereas others containing a greater number are abrupt and short in rhythm? Why again in periods do we get an impression of incompleteness, despite the fact that the sense is complete?
