Dear Valeria,

For unless there be a cause, there exists no first, essential, or necessary cause. Unless final causes are physical efficients, they could not operate, unless upon every theory of the mind. The fact of single and double vision cannot be explained consistently with any theory, and as being deducible from the general laws of causation. Such a theory is null, for two reasons; therefore, I encourage myself to hope for the future success and prevalence of my own notions. Firstly, for truth's sake, which is the Word of God ; secondly, for God's sake, because Atheists, more than all others, are feeling after Him, but cannot find Him, as ever existing, though invisible. To do this must be an honourable calling, and one which may prove successful whether I know it or not.

Yours sincerely,

Lady Mary Shepherd
