Hegel's Logic stands as one of philosophy's most exacting and ambitious works, here presented in a carefully revised translation from the Encyclopaedia of the Philosophical Sciences. Framed by bibliographical notice, Hegel's own prefaces, explanatory notes, and illustrations, it guides readers through the movement of thought from the opening problems of logic to Being, Essence, and the Notion, where reason seeks the deepest structure of reality. The volume also includes Hegel's defense of philosophy as necessary to religion, arguing that speculative thought does not abolish faith but clarifies and restores it, especially in a climate of attack from both rationalists and evangelicals. Throughout, philosophy and religion appear as two forms of the same truth, each incomplete without the other. The text further develops Hegel's account of opposition, contradiction, and Ground, showing how identity and difference depend on one another rather than cancel each other out. Extensive scholarly notes connect these ideas to Spinoza, Kant, Leibniz, Aristotle, and modern logicians and scientists, while also tracing debates over causality, judgment, syllogism, evolution, preformation, epigenesis, life, organism, and the relation between logic, nature, and self-consciousness.
