'At Maidstone, both on this occasion and subsequently when I served several months in separate confinement as a convict preparatory to going to Parkhurst, I was able, through the chaplain's kindness, to study not only Greek philosophy, but also Locke, Hume, Berkeley, Kant, Hegel, Fichte, Schelling, Schopenhauer, Fechner, Lotze, etc. Being a very rapid reader and having some ability in getting at the gist of a book I got through a fair amount of really interesting reading. ... In the summer I grabbed a book as soon as it was light enough to read, say, four o'clock, read till and during breakfast, dinner, supper and continued till 9:30 or 10 o'clock at night, an average of 8 to 10 hours a day. There were times, of course, when the burden of prison life bred a spirit of discontent and restlessness which books could not assuage.'
