Republication of two separate works originally published in 1851. The first had been delivered earlier as a lecture at the New York Mechanics Institute.

As originally published the two works were anticipated to be the first two in a series of publications presenting the author's solution to social problems of his time. A third was never issued. The present edition retains on the title pages of the parts their original numbering.

The true constitution of government in the sovereignty of the individual as the final development of Protestantism, democracy, and socialism

Cost the limit of price : a scientific measure of honesty in trade as one of the fundamental principles in the solution of the social problem.
