The way of regarding music which is illustrated in this passage, and in all that is said on the subject by Greek writers, is so typical of the whole point of view of the Greeks, that we may be pardoned for insisting once again on the attitude of mind which it implies. Music, as we saw, had an ethical value to the Greeks; but that is not to say that they put the ethics first, and the music second, using the one as a mere tool of the other. Rather an ethical state of mind was also, in their view, a musical one. In a sense something more than metaphorical, virtue was a harmony of the soul. The musical end was thus identical with the ethical one. The most beautiful music was also the morally best, and _vice versa_; virtue was not prior to beauty, nor beauty to virtue; they were two aspects of the same reality, two ways of regarding a single fact; and if aesthetic effects were supposed to be amenable to ethical judgment, it was only because ethical judgments at bottom were aesthetic. The "good" and the "beautiful" were one and the same thing; that is the first and last word of the Greek ideal. And while thus, on the one hand, virtue was invested with the spontaneity and delight of art, on the other, art derived from its association with ethics emotional precision. In modern times the end of music is commonly conceived to be simply and without more ado the excitement of feeling. Its value is measured by the intensity rather than the quality of the emotion which it is capable of arousing; and the auditor abandons himself to a casual succession of highly wrought moods as bewildering in the actual experience as it is exhausting in the after-effects. In Greek music, on the other hand, if we may trust our accounts, while the intensity of the feeling excited must have been far less than that which it is in the power of modern instrumentation to evoke, its character was perfectly simple and definite. Melody, rhythm, gesture and words, were all consciously adapted to the production of a single precisely conceived emotional effect; the listener was in a position clearly to understand and appraise the value of the mood excited in him; instead of being exhausted and confused by a chaos of vague and conflicting emotion he had the sense of relief which accompanies the deliverance of a definite passion, and returned to his ordinary business "purged", as they said, and tranquillised, by a process which he understood, directed to an end of which he approved.
