PlutarchNature without learning is like a blind man; learning without Nature, like a maimed one; practice without both, incomplete. As in agriculture a good soil is first sought for, then a skilful husbandman, and then good seed; in the same way nature corresponds to the soil, the teacher to the husbandman, precepts and instruction to the seed.
PlutarchNothing can produce so great a serenity of life as a mind free from guilt and kept untainted, not only from actions, but purposes that are wicked. By this means the soul will be not only unpolluted but also undisturbed. The fountain will run clear and unsullied.
