America...You Kill Me

1961, UN speech
Context: I do not ignore the remaining problems of traditional colonialism which still confront this body. Those problems will be solved, with patience, good will, and determination. Within the limits of our responsibility in such matters, my Country intends to be a participant and not merely an observer, in the peaceful, expeditious movement of nations from the status of colonies to the partnership of equals. That continuing tide of self-determination, which runs so strong, has our sympathy and our support. But colonialism in its harshest forms is not only the exploitation of new nations by old, of dark skins by light, or the subjugation of the poor by the rich. My Nation was once a colony, and we know what colonialism means; the exploitation and subjugation of the weak by the powerful, of the many by the few, of the governed who have given no consent to be governed, whatever their continent, their class, their color.

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.
