How far the persons whose diseases have been mentioned, should be considered as responsible to human or divine laws for their actions, and where the line should be drawn that divides free agency from necessity, and vice from disease, I am unable to determine.

We are encouraged to undertake this enterprise of humanity, by the sameness of the laws which govern the body and the moral faculties of man.
