Abstract: This paper examines Molinari’s assessment in two articles he wrote at the turn of the 20th century of the achievements of liberty in the 19th century and his prognosis for liberty in the coming 20th century. Concerning the latter, he successfully predicted two related things: firstly, that anti-liberal policies being introduced in the late 19th and early 20th centuries would inevitably lead to a long period of economic crisis and political oppression brought about by war, imperialism, socialist revolution and government intervention in the economy; and secondly, that once this dark period of “statism” had run its course, the benefits of individual liberty and the free market would be rediscovered and the classical liberal reforms the classical liberals had advocated in the 19th century would be introduced once again. His successful predictions need to be seen against the unsuccessful predictions of socialists of all kinds made in the same period. Whether democratic socialist or revolutionary (Marxist) socialist, the predictions of inevitable socialist revolution bringing about peace, prosperity and freedom for the mass of people have been proven to be hopelessly wrong by the extraordinary events of the 20th century. The paper also includes three appendices of Molinari’s writings (in French) from this period.
