The whole of life is but a moment of time. It is our duty, therefore to use it, not to misuse it.
PlutarchNo man ever wetted clay and then left it, as if there would be bricks by chance and fortune.
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.
Plutarch
