Clemente de Alejandría (150–215) historiador cristiano
Original: «But the art of sophistry, which the Greeks cultivated, is a fantastic power, which makes false opinions like true by means of words. For it produces rhetoric in order to persuasion, and disputation for wrangling. These arts, therefore, if not conjoined with philosophy, will be injurious to every one». <br class="br">Fuente: The Sacred Writings of Clement of Alexandria. Clement of Alexandria.
