Abstract
In Charles Renouvier we have one of the lone, stern, and indefatigable workers in philosophy in the nineteenth century. His powerful mind, moral earnestness, and intellectual vigour command respect and attention and place him high in the ranks of the philosophical thinkers of his century. He differed profoundly from his English contemporary Spencer and his German contemporary Lotze, both of whom have received more attention than Renouvier. His long and immensely active life fell into periods which coincide with, and partly reflect, the political and intellectual fortunes of his country from the Battle of Waterloo, through the Revolution of 1830, the Second Republic of 1848, the Second Empire, the War and the Commune of 1871, into the Third Republic, with its Dreyfus struggles and its Educational and Disestablishment problems in the early years of the present century
