All 3 Uses of

insolent
in
Utopia, by Thomas More

For when, by wandering about, they have worn out both their health and their clothes, and are tattered, and look ghastly, men of quality will not entertain them, and poor men dare not do it, knowing that one who has been bred up in idleness and pleasure, and who was used to walk about with his sword and buckler, despising all the neighbourhood with an insolent scorn as far below him, is not fit for the spade and mattock; nor will he serve a poor man for so small a hire and in so low a diet as he can afford to give him.'†
*

and to restrain the people, that they might not become too insolent—and that none might factiously aspire to public employments, which ought neither to be sold nor made burdensome by a great expense, since otherwise those that serve in them would be tempted to reimburse themselves by cheats and violence, and it would become necessary to find out rich men for undergoing those employments, which ought rather to be trusted to the wise.†

They all live easily together, for none of the magistrates are either insolent or cruel to the people; they affect rather to be called fathers, and, by being really so, they well deserve the name; and the people pay them all the marks of honour the more freely because none are exacted from them.†
