"The Phenomenology of Mind" in the original German. First published in 1807. According to Wikipedia: "Georg Wilhelm Friedrich Hegel (August 27, 1770 – November 14, 1831) was a German philosopher, and with Johann Gottlieb Fichte and Friedrich Wilhelm Joseph Schelling, one of the creators of German idealism. Hegel influenced writers of widely varying positions, including both his admirers (Bauer, Feuerbach, Marx, Bradley, Dewey, Sartre, Küng, Kojève, Žižek), and his detractors (Schelling, Kierkegaard, Schopenhauer, Nietzsche, Peirce, Russell). Hegel developed a comprehensive philosophical framework, or "system", to account in an integrated and developmental way for the relation of mind and nature, the subject and object of knowledge, and psychology, the state, history, art, religion, and philosophy. In particular, he developed a concept of mind or spirit that manifested itself in a set of contradictions and oppositions that it ultimately integrated and united, such as those between nature and freedom, and immanence and transcendence, without eliminating either pole or reducing it to the other. His influential conceptions are of speculative logic or "dialectic," "absolute idealism," "Spirit," negativity, sublation (Aufhebung in German), the "Master/Slave" dialectic, "ethical life," and the importance of history." --This text refers to the Kindle Edition edition.
