My research falls into two categories: 1- Philosophy: Hegel, Feuerbach, and Marx, epistemology, logic, and religion. 2- Sociology of knowledge, religion and nationalism. Major contribution: The Classical Theory of Alienation; and the Arabic translation of Marx's Das Capital. I write in English and Arabic. Some of contributions are available in German. For my major contributions in Arabic consult google, Saqi Books, Kamel publishers, Farabi publishers, among others.
