In l’Année Philosophique of 1893, F. Pillon labeled “radical idealism or immaterialism, the doctrine that denies extended substance, matter” as “the true philosophy” of the 19th century. Immaterialism was the teaching of Bishop George Berkeley (1685-1753), offered as the direct opposite of materialism, the best intellectual weapon against atheism and skepticism: in brief, minds and their ideas are the only reality. There is no unthinking, unperceived material substratum: everything that exists does so only because it is perceived, whether the observer is an individual “spirit” or God himself.
But, Berkeley didn’t invent it from nothing. Pillon adds that this doctrine “has its direct source in writings from the end of the previous century”. This book tells the origin story of immaterialism; here are collected the principal texts in which this doctrine originated, evolved, ripened.
