Abstract
José Joaquín Fernández de Lizardi was a prolific author that wrote poetry, theater, novels, journals, dramas, letters and booklets with a sincere and colloquial style, impregnated with anecdotes, sayings, well-known phrases and moral lessons directed to the common people. However, his adverse opinions, both towards the government and the colonial administration, won him a great number of enemies who criticized severely his journalistic and literary production. His adversaries, Juan María Lacunza among them, reproached his literary "quacking", that dared mixing "with the soft singing of a multitude of American swans... glory and ornament of the Mexican Valley". Nonetheless, Fernández de Lizardi also had friends and defenders; one of them was Guillermo Prieto, to whom El Pensador Mexicano set up as "the sun of the free press".
