The fourth consists in omens, when, for example, a man from any words which others may have spoken on purpose, or by accident, pretends to gather a way of looking into and knowing anything of futurity. The fifth is chiromancy, which consists in making a pretence to the knowledge of future things by the figures and the lines of the hands; and if it be by consulting the shoulder-bones of any beast, it goes by the name of spatulamancy. * * * * * As the first kind of divination, by a tacit invocation of the devil is divided into the five species above mentioned; so also is the second kind of tacit divination, or invocation of the devil, divided into two species by St. Thomas of Aquin. _Secunda Secundae, questione nonagesima quinta articulo tertio_, and too tedious to insert here. Now all these ways are by these divines counted wicked, and I set them down that people may avoid them. For how many gipsies and pretenders to chiromancy have we in London and in the country? How many that are for hydromancy, that pretend in water to show men mighty mysteries? And how many in geomancy, with their beryls and their glasses, that, if they are not under the instigation of the devil, propagate the scandal at least by being cheats, and who ought to be punished to the utmost severity, as our English laws enact? Mr. Campbell, who hates, contemns, and abhores these ways, ought, methinks, to be encouraged by their being restrained; and people of curious tempers, who always receive from him moral and good instructions, which make them happy in the conduct of life, should be animated in a public manner to consult him, in order to divert the curious itch of their humours from consulting such wicked impostors, or diabolical practisers, as too frequently abound in this nation, by reason of the inquisitive vulgar, who are more numerous in our climate, than any I ever read of. But now to argue the case of conscience with regard to his particular practice by way of the second-sight, whether, _in foro conscientiae_, it is lawful for him to follow it, or others to consult him? The divines above mentioned having never had any notice of that faculty in all likelihood, or if they had, never mentioned it, makes it a point more difficult for me to discuss; but I think they have stated some cases, by the making of which my premises, I can deduce from all the learned men I have above quoted, a conclusion in favour of our Mr. Duncan Campbell, and of those who consult him; but my opinion shall be always corrected by those who are wiser than myself, and to whom I owe entire submission. I take leave to fix these premises from them first, and to form my argument from them afterwards in the following manner:-- First, It is allowed by all these divines, that a knowledge which one may have of future things within the order of nature, is and may be lawful.
