Passion is seen in the groups made by speaker and listener, or thinker and receiver, or actor and spectator, but it appears most vital and strong in the love of the lover and the response of the beloved. The passion of the poet is in his poetry; the passion of the musician composes melody; the passion of the actor declaims his part. The act of creation, in no matter what aspect, is the play of passion, whose source and root is love alone; for as man without humanity is empty, and as the body without spirit is dead, so passion without love is energy that is devoid of beauty and blind.
