Geoffrey Chaucer,
The Wife of Bath’s Tale
“ For, God wot, men may full often see a lord's son do shame and dishonour. And he that would have praise for his gentility, because he was born of a gentle house, and had ancestors virtuous and noble, and will do no gentle deeds himself, nor imitate his gentle ancestor, he is not gentle, be he a duke or a prince ; for rude, sinful deeds make a churl. For gentleness which is but the renown of thine ancestors for their high worth is a thing strange to thine own person; thy gentleness cometh to thee from God alone; true gentleness, then, cometh unto us by grace ”
