Note 4 — Chapter I
Reading edition
In such histories of intellectual development as I have read, too little attention is paid to the dates at which certain copyrights have expired and the other dates at which "popular editions" have been issued. Cheap printing, often aided by this new freedom to print, made available to the boys of my generation a vast literature of history, biology, politics, economics and theology. Darwin, Huxley, J. S. Mill and Carlyle were but a few of those who lay at our disposal.
