Quotes

 * There is no other difference between an olive and a wild olive tree; or between a crab and an apple and other fruits of this kind; but that some are cultivated in gardens, and are a sort of domestic fruits, whilst the others grow wild in woods and fields. Now we ought to esteem him alone an agreeable and good-natured man, who, in his daily intercourse with others, behaves in such a manner as friends usually behave to each other.

 * Giovanni della Casa, Galateo: Or, A Treatise on Ppoliteness and Delicacy of Manners, pp. 42-43
