John Addington Symonds,
A Problem in Modern Ethics
(1896)
“ The evidence of ancient Greece, schools, prisons, and sotadic races, compels us to believe that normally healthy people are often born with these instincts or else acquire them by the way of custom. Again, his insinuation that onanism, regarded as the main exciting cause, is more frequent among young people of abnormal inclinations than among their normal brethren, will not bear the test of common observation and of facts communicated in the autobiographies of professed onanists and confessed Urnings. ”
