“Thought must never submit, neither to a dogma, nor to a party, nor to a passion, nor to an interest, nor to a preconceived idea, nor to whatever it may be, save to the facts themselves, because, for thought, submission would mean ceasing to be.”
La pensée ne doit jamais se soumettre, ni à un dogme, ni à un parti, ni à une passion, ni à un intérêt, ni à une idée préconçue, ni à quoi que ce soit, si ce n'est aux faits eux-mêmes, parce que, pour elle, se soumettre, ce serait cesser d'être.

Plygu rhag llid yr ydwyf,
Pla ar holl ferched y plwyf!
Am na chefais, drais drawsoed,
Onaddun' yr un erioed
Na morwyn fwyn ofynaig,
Na merch fach, na gwrach, na gwraig.

Context: But neither can anything we desire be got without money, or what money represents, i. e. without the command of exchangeable things. All the things that we so often say "cannot be had for money" we might with equal truth say cannot be had or enjoyed without it. Friendship cannot be had for money, but how often do the things that money commands enable us to form and develop our friendships! … But even "waiting" requires money, if not so much as marrying does. In fact, a man can be neither a saint, nor a lover, nor a poet, unless he has comparatively recently had something to eat. The things that money commands are strictly necessary to the realisation on earth of any programme whatsoever. The range of things, then, that money can command in no case secures any of those experiences or states of consciousness which make up the whole body of ultimately desired things, and yet none of the things that we ultimately desire can be had except on the basis of the things that money can command. Hence nothing that we really want can infallibly be secured by things that can be exchanged, but neither can it under any circumstances be enjoyed without them.
