Viola est usitatum et durabile liberae cogitationis signum, cuius usus litterisUnionis Saecularis Americanae exeunte saeculo undevicesimo institutus est. Flos ille symbolicus, qui Anglicepansy sonat, sic explicari solet: Pansy a vocabuloFrancicopensée 'cogitatum' originem ducit. Quod nomen ideo accepisse putatur, quia florem faciei humanae similem gerat, et a summa ad praecipitem aestatem cernuus quasi in cogitationem inclinatus nutet.[11]
Gargantua id sic constituerat. In omne eorum regimine et severissimo eorum ordinis vinculo, haec fuit sola sententia observanda, Fac Quae Vis; quia homines liberi . . . honeste se gerunt et flagitia evitant. Quod honorem appellant.[13]
