Are cradled into poetry by wrong;
They learn in suffering what they teach in song.”

I take that to mean that any man who entrusts to language the task of presenting the ineffable Light is really and truly a liar; not because of any hatred on his part of the truth, but because of the feebleness of his instrument for expressing the thing thought of.

Context: Finally, attention must be drawn to one of the most important consequences of colonialism on African development, and that is the stunting effect on Africans as a physical species. Colonialism created conditions which led not just to periodic famine but to chronic undernourishment, malnutrition, and deterioration in the physique of the African people. If such a statement sounds wildly extravagant, it is only because bourgeois propaganda has conditioned even Africans to believe that malnutrition and starvation were the natural lot of Africans from time immemorial. A black child with a transparent rib cage, huge head, bloated stomach, protruding eyes, and twigs as arms and legs was the favorite poster of the large British charitable operation known as Oxfam. The poster represented a case of kwashiorkor—extreme malignant malnutrition. Oxfam called upon the people of Europe to save starving African and Asian children from kwashiorkor and such ills. Oxfam never bothered their consciences by telling them that capitalism and colonialism created the starvation, suffering, and misery of the child in the first place. There is an excellent study of the phenomenon of hunger on a world scale by a Brazilian scientist, Josue de Castro. It incorporates considerable data on the food and health conditions among Africans in their independent pre-colonial state or in societies untouched by capitalist pressures; and it then makes comparisons with colonial conditions. The study convincingly indicates that African diet was previously more varied, being based on a more diversified agriculture than was possible under colonialism. In terms of specific nutritional deficiencies, those Africans who suffered most under colonialism were those who were brought most fully into the colonial economy: namely, the urban workers.

En France, et dans la partie la plus grave de l'histoire moderne, aucune femme, si ce n'est Brunehault ou Frédégonde, n'a plus souffert des erreurs populaires que Catherine de Médicis; tandis que Marie de Médicis, dont toutes les actions on été préjudiciables à la France, échappe à la honte qui devrait couvrir son nom... Catherine de Médicis, au contraire, a sauvé la couronne de France; elle a maintenu l'authorité royale dans des des circonstances au milieur desquelles plus d'un grand prince aurait succombé.Ayant en tête des factieux et des ambitions comme celles des Guise et de la maison de Bourbon, des hommes commes les deux cardinaux de Lorraine et comme les deux Balafrés, les deux princes de Condé, la reine Jeanne d'Albret, Henri IV, le connétable de Montmorency, Calvin, les Coligny, Théodore de Bèze, il lui a fallu déployer les plus rares qualités, les plus précieux dons de l'homme d'État, sous le feu des railleries de la presse calviniste.
