Persuasion, by Jane Austen
(Auto-generated)

She had a cultivated mind, and was, generally speaking, rational and consistent; but she had prejudices on the side of ancestry; she had a value for rank and consequence, which blinded her a little to the faults of those who possessed them.†
Chpt 2 *

cultivated = developed, grown, or prepared for growing crops
Anne always contemplated them as some of the happiest creatures of her acquaintance; but still, saved as we all are, by some comfortable feeling of superiority from wishing for the possibility of exchange, she would not have given up her own more elegant and cultivated mind for all their enjoyments; and envied them nothing but that seemingly perfect good understanding and agreement together, that good-humoured mutual affection, of which she had known so little herself with either of her sisters.†
Chpt 5
Mr Hayter had some property of his own, but it was insignificant compared with Mr Musgrove's; and while the Musgroves were in the first class of society in the country, the young Hayters would, from their parents' inferior, retired, and unpolished way of living, and their own defective education, have been hardly in any class at all, but for their connexion with Uppercross, this eldest son of course excepted, who had chosen to be a scholar and a gentleman, and who was very superior in cultivation and manners to all the rest.†
Chpt 9
