To G. H. Darwin 21 October [1873]
Summary
CD gives his criticisms of GHD’s essay on religion and the moral sense. Urges him to delay publishing for some months and then to consider whether it is new and important enough to counterbalance the effects of its publication. J. S. Mill would never have influenced the age as he has done had he not refrained from expressing his religious convictions. Cites John Morley’s Life of Voltaire [1872]: direct attacks produce little effect; real good comes from slow and silent side attacks. "My advice is to pause, pause, pause."
