Depend upon it there comes a time when for every addition of knowledge you forget… — Arthur Conan Doyle

There is nothing in which deduction is so necessary as in religion. It can be built 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 powers, our desires, our food, are 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.
