Condillac's sensualist epistemology used to be combined with Locke's empiristic accomplishments, following Condillac's opinion himself. The French philosopher, while appreciating this solution, sought to develop it, and in particular he wished to make it more profound. He wanted to formulate special 'metaphysics' of knowledge, the synonym of genetic analyses that were supported to answer the question: how and why is knowledge possible? The author proves that, like in the case of Locke, the point of reference in Condillac's epistemology was Descartes' solution, including his theory of science.
