In plain words

Speech went out. Having stayed away a year, it came back and said, "How could you live without me?" They said, "As dumb men live, not speaking with speech but breathing with the breath, seeing with the eye, hearing with the ear, knowing with the mind, begetting with the seed — so we lived." And speech entered in again.
