Michel de Montaigne,
The Essays of Montaigne — Chapter XXXVI. Of Cato the Younger…
(1877)
“ The fury that possesses him who is able to penetrate into it wounds yet a third man by hearing him repeat it; like a loadstone that not only attracts the needle, but also infuses into it the virtue to attract others. And it is more evidently manifest in our theatres, that the sacred inspiration of the Muses, having first stirred up the poet to anger, sorrow, hatred, and out of himself, to whatever they will, does moreover by the poet possess the actor, and by the actor consecutively all the spectators. So much do our passions hang and depend upon one another. ”
