Whether we ought to distinguish several species of divination?

❌ Objection 1 : It would seem that we should not distinguish several species of divination. Where the formality of sin is the same, there are not seemingly several species of sin. Now there is one formality of sin in all divinations, since they consist in entering into compact with the demons in order to know the future. Therefore there are not several species of divination.

❌ Objection 2 : Further, a human act takes it species from its end, as stated above (FS, Question [1], Article [3]; FS, Question [18], Article [6]). But all divination is directed to one end, namely, the foretelling of the future. Therefore all divinations are of one species.

❌ Objection 3 : Further, signs do not vary the species of a sin, for whether one detracts by word writing or gestures, it is the same species of sin. Now divinations seem to differ merely according to the various signs whence the foreknowledge of the future is derived. Therefore there are not several species of divination.
