“[II-II, Q. 96, Art. 3] Whether Observances Directed to the Purpose of Fortune-telling Are Unlawful? Objection 1: It would seem that observances directed to the purpose of fortune-telling are not unlawful. Sickness is one of the misfortunes that occur to man. Now sickness in man is preceded by certain symptoms, which the physician observes. Therefore it seems not unlawful to observe such like signs. Obj. 2: Further, it is unreasonable to deny that which nearly everybody experiences.” source
