The time is approaching, Mr. Guillaumin, when an all-out fight will be fought between Socialism and Political Economy; between prohibition and non-prohibition, between democracy and monarchy, etc. This battle must not use the cannon, but the press. If you want it, you are in a position to make your store the battleground of all ideas. Remain impartial, seize all opportunities, create them if necessary, and your part in the revolution which is brewing will be one of the best. You know what role the printer and bookseller Panckoucke played in the 18th century; you can surpass it by all the superiority that our century has over the previous one.
