A quote I dug up in my notes from Arthur Conan Doyle’s Complete Sherlock Holmes
He walked past the couch to the open window, and held up the drooping stalk of a moss-rose, looking down at the dainty blend of crimson and green. It was a new phase of his character to me, for I had never before seen him show any keen interest in natural objects.
“There is nothing in which deduction is so necessary as in religion,” said he, leaning with his back against the shutters. “It can be build up as an exact science by the reasoner. Our highest assurance of the goodness of Providence seems to me to rest in the flowers. All other things, our power, our desires, our food, are all really necessary for our existence in the first instance. But this rose is an extra. Its smell and its color are an embellishment of life, not a condition of it. It is only goodness which gives extras, and so I say again that we have much to hope from the flowers.”
It seems to me that this notion of religion and Providence as nature in general was essential to the Victorian worldview, as Doyle (via Holmes’ quote) clearly acknowledges here.
