 Plato also offers some discussion of the standards of music and poetry in their own right in the course of his discussion of education. As in other works, Plato is quite critical of the ethical content of poetry and the ethical knowledge possessed by the poet (see e.g. Laws 719A–C, 811B–E) and heavily censors the poetry that will be allowed into the city (see e.g. Laws 657B, 719B–D, 796E–802E). Plato also here offers a somewhat obscure discussion of the standard for correctness in music, saying both that it must be judged by the pleasure of the virtuous man (Laws 659A) and that, because music is imitative, the standard must involve not pleasure but truth, and that correct music is music which resembles the imitation of the beautiful (Laws  668A–B).[51]
