Brissot became known as a writer and was engaged on the "Mercure de France", the "Courrier de l'Europe" and other papers. Devoted to the cause of humanity, he proposed a plan for the collaboration of all European intellectuals. His newspaper "Journal du Lycée de Londres", was to be the organ of their views. The plan was unsuccessful. Soon after his return to Paris, Brissot was placed in the Bastille in 1784 on the charge of having published a pornographic pamphlet "Passe-temps de Toinette" against the queen. Brissot had a falling out with Catholicism, and wrote about his disagreements with the church's hierarchical system.
