All well and good, but ... 1

Okay for the analysis of the rise of relativism, indisputable and formally established by all practicing philosophy professors. Okay probably also to show that relativism is the mortal enemy of philosophical and rigorous thought. But reducing this aspiring to universal thought in the Enlightenment and its philosophers, that's a bit fast ... The philosophy and his search for universal principles have not started in the eighteenth century, but with the ancient Greeks. Worse, who are the advocates of cultural relativism, if Diderot, Montesquieu, Voltaire and friends? It is they who, fighting against the universality of the Church instilled in the West the systematic questioning legitimate certainties of European multi centenary culture and propagated the idea that truth was worth less that freedom in all areas, and especially the freedom to enrich unhindered ... "We must cultivate his garden," said Voltaire, who added in private "and especially keep his tithes." The universality of Enlightenment is a concept that deserves more research, and we regret that the author did make a simple ultimate refuge of suffering humanity, without going further in the critical analysis.
