Beginning with the third edition, Proudhon intends to consider doctrines on the stock market or the ―temple of speculation‖ that derive from his political and social writing. He wants to assess stock market speculation in relation to general social standards or ―public morals‖ and to ―economic development‖ of his era. The unrestrained speculative development during the first half of the 19th century is for Proudhon simply a reflection of a corrupted social and economic system and a forewarning of an insurmountable barrier for the economic mechanism that should deliver a just and sustainable society - ―the industrial republic.‖ The object.
