“Yet all does the sire himself ruthlessly condemn to the murky flames, and bid his own signs of rank be borne withal, if by their loss he may sate his devouring grief.”

Acontece tener un padre un hijo feo y sin gracia alguna, y el amor que le tiene le pone una venda en los ojos para que no vea sus faltas, antes las juzga por discreciones y lindezas y las cuenta a sus amigos por agudezas y donaires.
Don Quixote de la Mancha (1605–1615), Prologue

Che chi si truova in degno laccio preso,
Se ben di sé vede sua donna schiva,
Se in tutto aversa al suo desire acceso;
Se bene Amor d'ogni mercede il priva,
Poscia che 'l tempo e la fatica ha speso;
Pur ch'altamente abbia locato il core,
Pianger non de', se ben languisce e muore.
Canto XVI, stanza 2 (tr. B. Reynolds)

Context: Only a few years ago there was a great awakening of the human mind. Men began to inquire by what right a crowned robber made them work for him? The man who asked this question was called a traitor. Others asked by what right does a robed hypocrite rule my thought? Such men were called infidels. The priest said, and the king said, where is this spirit of investigation to stop? They said then and they say now, that it is dangerous for man to be free. I deny it. Out on the intellectual sea there is room enough for every sail. In the intellectual air there is space enough for every wing.
The man who does not do his own thinking is a slave, and is a traitor to himself and to his fellow-men.
