As theories increased, simple medicines..were forgotten, at least in the politer nations. ...Medical books, were immensely multiplied,...(towards) an abstruse science, quite out of reach of ordinary men.
John WesleyAll outward means of grace, if separate from the spirit of God, cannot profit, or conduce, in any degree, either to the knowledge or love of God. All outward things, unless he work in them and by them, are in vain.
John Wesley
