Karl Christian Friedrich Krause left an impressive oeuvre consisting of 256 books and articles, covering numerous branches of philosophy, the humanities, and science.[1] His Urbild der Menschheit, his Vorlesungen über das System der Philosophie and his Vorlesungen über die Grundwahrheiten der Wissenschaft are of particular pertinence for philosophers today.
