In December 1866, mathematician Mary Boole wrote to Charles Darwin:
Do you consider the holding of your Theory of Natural Selection, in its fullest & most unreserved sense, to be inconsistent,—I do not say with any particular scheme of Theological doctrine,—but with the following belief, viz: That knowledge is given to man by the direct Inspiration of the Spirit of God. That God is a personal and Infinitely good Being. That the effect of the action of the Spirit of God on the brain of man is especially a moral effect.
