. Krausism, when considered in its totality as a complete, stand-alone philosophical system, had only a small following in Germany, France, and Belgium, in contradistinction to certain other philosophical systems (such as Hegelianism) that had a much larger following in Europe at that time. However, Krausism became very popular and influential in

not as a complete, comprehensive philosophical system ''per se'', but as a broad cultural movement. In Spain, Krausism was known as "Krausismo", and Krausists were known as "Krausistas". Outside of Spain, the Spanish Krausist cultural movement was referred to as Spanish Krausism.

Early life

Krause was born in Eisenberg, Thuringia, in the duchy of Saxe-Gotha-Altenburg, Germany. His parents were Johann Friedrich Gotthard Krause (January 1, 1747 - February 17, 1825) and Christiana Friederica Böhme (1755 – December 21, 1784). Karl's father Johann was a teacher at the lyceum in Eisenberg, and in 1795 became a Lutheran pastor and hymn collector in Nobitz.

''Identitätsphilosophie'', panentheism, and other aspects of Krausism

Krause's philosophy, as a whole, is an example of what historians of philosophy refer to as ' (philosophy of identity). An ''Identitätsphilosophie'' is a philosophical system that posits the fundamental identity of spirit and nature. In Krause's philosophical system, the parts of the system which, technically, constitute its "panentheism", are only parts of a much broader whole. Therefore, although Krause's philosophy is accurately described as being "panentheistic", Krausism as a whole is better categorized as an ''Identitätsphilosophie'' which features panentheism as one of its primary fundamental components. Krause endeavoured to reconcile the ideas of a

Etymology of "panentheism"

Historians of philosophy usually give Krause sole and complete credit for "coining" (originating) the term "panentheism", in 1828. However, according to evidence provided by Philip Clayton, the German idealist philosopher

Friedrich Wilhelm Joseph von Schelling Friedrich Wilhelm Joseph Schelling (; 27 January 1775 – 20 August 1854), later (after 1812) von Schelling, was a German philosopher. Standard histories of philosophy make him the midpoint in the development of German idealism, situating him be ...

(1775-1854) had already used this term (albeit in a slightly different form - in the form of the phrase "pan + en + theism"), and also had discussed numerous concepts and issues related to it, in his ''Philosophische Untersuchungen über das Wesen der menschlichen Freiheit und die damit zusammenhängenden Gegenstände'' (1809) (''Philosophical Investigations into the Essence of Human Freedom and Matters Connected Therewith''). Additionally, Krause and Schelling scholars now recognize that Krause's philosophy, as a whole, reflects, and partially incorporates, many of the themes, concepts and insights present in Schelling's ''Naturphilosophie'' (Philosophy of Nature), which itself is a form of panentheism. It now appears that Schelling's work may have provided much more of the framework of Krausean panentheism than historians of philosophy in the past had realized. Based on Clayton's evidence, it is quite possible that Krause, who was well-acquainted with Schelling and his works, adopted at least some of the initial ''basic concepts'' of his own panentheistic system from various works of Schelling (especially from Schelling's ''Philosophical Investigations into the Essence of Human Freedom''), and then gradually developed these basic concepts into his own very elaborate version of panentheism. Looking forward, it might be more accurate for historians of philosophy to now say, that Schelling, in 1809, provided not only the terminological framework of Krausean panentheism, but also some of the ''basic concepts'' (at least), of what was to become Krausean panentheism, and that Krause not only adopted and greatly expanded upon these concepts and insights of Schelling's, but that he also adopted Schelling's phrase "pan + en + theism", and that in 1828 he merely reduced Schelling's phrase into a more concise and compact form (as the single term "panentheism"), in an attempt to succinctly and adequately describe - in a single term - the cosmo-theological aspects of his own philosophical system. In his published works, Krause first used the term "panentheism" (in its German-language form "panentheismus") in ''Vorlesungen über das System der Philosophie'' (Göttingen: 1828). The term "panentheismus" next appears in his ''Vorlesungen über die Grundwahrheiten der Wissenschaft, zugleich in ihrer Beziehung zu dem Leben. Nebst einer kurzen Darstellung und Würdigung der bisherigen Systeme der Philosophie, vornehmlich der neusten von Kant, Fichte, Schelling und Hegel, und der Lehre Jacobi's.'' (Göttingen: 1829). Krause argued that the world itself and mankind, its highest component, constitute an

. In his book ''Das System der Rechtsphilosophie'' (published posthumously in 1874), he argued that non-human animals should hold a right not to be subjected to pain as well as a right to general physical well-being. Krause rejected the anthropocentric premises of Fichte. He held the view that animals are persons whose rights must be protected by law.

Influence and works

The comparatively small area of Krause's influence was due partly to him being overshadowed by Schelling and Hegel, and partly to two difficulties present in his written works. The spirit of his thought is

and by no means easy to follow, and this problem is accentuated, even for German readers, by his use of artificial and/or invented terminology. He makes use of Germanized foreign terms which are unintelligible to the ordinary man. His principal works are (beside those quoted above): ''Entwurf des Systems der Philosophie'' (1804), ''System der Sittenlehre'' (1810), and ''Das Urbild der Menschheit'' (1811). He left behind at his death a mass of unpublished notes, some of which have been collected and published by his disciples K. D. A. Röder, J. H. Ahrens, F. W. T. Schliephake, H. K. von Leonhardi (Krause's son-in-law), Guillaume Tiberghien, and others.

became particularly influential in Spain in the 19th century, where Krause's ideas were introduced and promoted by Julián Sanz del Río (1814-1869), an academic based in Madrid. Krause's philosophy flourished in Spain (where it was known as "Krausismo") because it contains elements which were very appealing - at the time - to a diverse class of people. Krausism in Spain was popular and successful, more as a broad cultural movement rather than as a specialised form of cosmo-theology. As a cultural movement, it emphasised
