later became Paragraph 175 of the penal code of the German Empire, violated the "rights of man". He advanced the classic liberal argument that consensual sexual acts in private should not be subject to criminal law. He contended that the Prussian law allowed blackmailers to extort money from homosexuals and often drove them to suicide. Whether sexual preference was innate was called by Kerbeny "a very interesting riddle of nature" that was best excluded from arguments for the decriminalization of sexual practices. Instead, he considered the right of a government to intervene in private matters. He wrote: On the other hand, he repeatedly described one's sexual drive as "innate and unchanging". That contradicted the dominant view up to that time of men committing "sodomy" out of mere wickedness. Gay men, he said, were not by nature effeminate, and he pointed out that many of the great heroes of history were gay. With Heinrich Hössli and Karl Heinrich Ulrichs, he was among the first writers to put those now-familiar arguments before the public. In a letter written on 6 May 1868, Kertbeny published, in German the terms homosexual and heterosexual as part of his system for defining sexual types to replace the pejorative terms "sodomite" and "pederast", which were used in the German- and French-speaking world of his time. In addition, he called those who masturbate monosexualists and practitioners of anal intercourse pygists. He also used German terms that did not influence his contemporaries but suggest how he was considering terms that did not rely on classical languages, including Die Gleichegeschlechtlichen ("those of the same sex") and Der Gleichegeschlechtlicher Akt ("the same-sex act"). Kertbeny made no further contribution to the debates about homosexuality or its legal status or origins. In 1880, he offered a chapter on homosexuality for Gustav Jäger to include in his book Discovery of the Soul, but Jäger's publisher decided that it was too controversial and omitted it. Jäger nevertheless used Kertbeny's terminology elsewhere in the book. Death Kertbeny died in Budapest on 23 January 1882 at the age of 58. (1836–1894) eulogized him: "He devoted his life to serving his country, even when he was living abroad. He publicised our glory there amongst foreign peoples. His first literary activities were received with mockery, but he did not give up and he brought light to Hungarian literature for foreign people".
