Adamantios Korais (1748-1833) was a graduate of the University of Montpellier in 1788 and he spent most of his life as an expatriate in Paris. A classical scholar, Korais was repelled by the Byzantine influence in Greek society and was a fierce critic of the ignorance of the clergy and their subservience to the Ottoman Empire. He realized that education was a precursor to Greek liberation. He invented Kathareuousa.
