a woman is a monstrous thing. Deliberately to withdraw from coitus in order that semen may fall on the ground is double monstrous." Methodism founder John Wesley, according to Bryan C. Hodge, "believed that any waste of the semen in an unproductive sexual act, whether that should be in the form of masturbation or coitus interruptus, as in the case of Onan, destroyed the souls of the individuals who practice it". He writes his Thoughts on the Sin of Onan (1767), which was reproduced as A Word to Whom it May Concern on 1779, as an attempt to censor a work by Samuel-Auguste Tissot. In that writing, Wesley warns about "the dangers of self pollution", the bad physical and mental effects of masturbation, writes many such cases along with the treatment recommendations. Disputes According to some Bible critics who contextually read this passage, the description of Onan is an origin myth concerning fluctuations in the constituency of the tribe of Judah, with the death of Onan reflecting the dying out of a clan;Cheyne and Black, Encyclopedia Biblica Er and Onan are hence viewed as each being representative of a clan, with Onan possibly representing an Edomite clan named Onam, mentioned by an Edomite genealogy in Genesis. Biblical scholars universally agree that the biblical story of Onan is not about masturbation nor about contraception per se or the "wasting of semen" but his refusal to fulfill his obligation of levirate-marriage with Tamar by committing coitus interruptus. The text emphasizes the social and legal situation, with Judah explaining what Onan must do and why. A plain reading of the text is that Onan was killed because he refused to follow instructions. Scholars have argued that the secondary purpose of the narrative about Onan and Tamar, of which the description of Onan is a part, was to either assert the institution of levirate marriage or present a myth for its origin; Onan's role in the narrative is, thus, as the brother abusing his obligations by agreeing to sexual intercourse with his dead brother's wife, but refusing to allow her to become pregnant as a result. Emerton regards the evidence for this to be inconclusive, although classical rabbinical writers argued that this narrative describes the origin of levirate marriage. John M. Riddle argues that "Epiphanius (fourth century) construed the sin of Onan as coitus interruptus". John T. Noonan Jr. says that "St. Epiphanius gave
