For instance, a new-born child: he has come from heaven, he is as happy as the angels, he is beautiful in infancy, he is an expression of harmony, and he is love himself; and yet he does not know love, harmony, and beauty. Why? Because he does not yet know duty. But the moment the spirit of duty is wakened in a person poetry begins; and when poetry is begun, then love, harmony and beauty manifest to his view fully.
