Alongside with my interest in poetry, went an intense interest in religion and philosophy. My grandfather was Anglican, my grandmother was a Scotch Presbyterian, but gradually became a Unitarian. I was taken on alternate Sundays to the (Episcopalian) Parish Church at Petersham and to the Presbyterian Church at Richmond, while at home I was taught the doctrines of Unitarianism. It was these last that I believed until about the age of fifteen.
