CONDILLAC, Principes Généraux de Grammaire, 1797

Étienne Bonnot de Condillac (1714-1780) was a French philosopher and logician, a major figure in sensualism and the Enlightenment. His philosophy emphasized the sensory origin of all our knowledge. His work on grammar, like this book, is part of an empiricist and analytical approach, seeking to identify universal principles governing language through the observation and analysis of sensations.
