'The country parson is full of all knowledge. They say it is an ill mason that refuseth any stone; and that there is no knowledge, but in a skilful hand serves either positively as it is, or else to illustrate some other knowledge. He condescends even to the knowledge of tillage and pasturage, and makes great use of them in teaching, because people by what they understand are best led to what they understand not.'
George Herbert, 'The Country Parson' in The Complete English Works, p.200.
