Divination is the art of predicting the future. Various methods are described, including tea leaves, fire omens, crystal balls, palmistry, cartomancy (including the reading of conventional playing cards and the tarot), astrology, and dream interpretations. Supporters of the subject claim that it is an inexact science that requires innate gifts like the "Inner Eye". Those opposed claim that the subject is irrelevant and fraudulent. The class is taught by Professor Trelawney.
