contra Nietzsche, i actually find some of aristotle's observations stimulating, such as the following:
As far as possible, too, the dramatic poet should carry out the appropriate gestures as he composes his speeches, for of writers with equal abilities those who can actually make themselves feel the relevant emotions will be the most convincing--agitation or rage will be most vividly reproduced by one who is himself agitated or in a passion. Hence poetry is the product either of a man of great natural ability or of one not wholly sane; the one is highly responsive, the other possessed.
(Tr. T.S. Dorsch)
