by decades, in chapter 6 of ''Hatata'', starting the chapter with: "All men are equal in the presence of God; and all are intelligent since they are his creatures; he did not assign one people for life, another for death, one for mercy, another for judgment. Our reason teaches us that this sort of discrimination cannot exist." In chapter 5 of ''Hatata'', he criticizes slavery saying, "what the Gospel says on this subject cannot come from God. Likewise, the Mohammedans said that it is right to go and buy a man as if he were an animal. But with our intelligence, we understand that this Mohammedan law cannot come from the creator of man who made us equal, like brothers, so that we call our creator our father." At the time, slavery was widely practiced in Ethiopia.


Authorship controversy

The authorship of the ''Hatata'' was initially challenged by Carlo Conti Rossini in 1920, who proposed that it had been forged by Father Giusto da Urbino, an Italian Capuchin missionary active in Ethiopia during the 19th century. Rossini's argument was based on extrinsic factors: the relatively recent age of the surviving manuscripts, Urbino’s familiarity with Ethiopic (Geʽez) and Islamic sources, and the fact that he was the first to discover the extant copies. In 1934, Eugen Mittwoch added linguistic critiques to the forgery hypothesis, and as a result, international scholarly interest in the work declined during much of the 20th century. However, the authenticity of the ''Hatata'' has since been strongly defended by multiple Ethiopian and international scholars. Amsalu Aklilu and Alemayehu Moges argued for its Ethiopian origin based on its secular tone, syntactic structure, and the particularities of its Geʽez usage. Philosopher Claude Sumner rejected the forgery claim in 1976, presenting newly discovered letters by Urbino archived in Rome. He offered statistical and philological evidence showing that the ideas expressed in the ''Hatata'' diverged significantly from Urbino’s known theological views and exceeded his demonstrated proficiency in Geʽez. Sumner also pointed to differing biblical citation patterns between the two treatises (''Hatata Zera Yacob'' and ''Hatata Walda Heywat'') as further indication of dual authorship. As of the late 20th and early 21st centuries, the majority of scholars support Zera Yacob as the authentic author of the ''Hatata'', and the forgery hypothesis is widely regarded as outdated and lacking in substantive evidence.Temesgen Gebrehiwot, "The Rationalist Philosophy of Zera Yacob: Reconsidering Its Historical Context and Legacy", in: ''Journal of Ethiopian Studies'', Vol. 50, No. 1 (2020), pp. 57–72.
