Schellingian

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 between Johann Gottlieb Fichte, his mentor in his early years, and Georg Wilhelm Friedrich Hegel, his one-time university roommate, early friend, and later rival. Interpreting Schelling's philosophy is regarded as difficult because of its evolving nature.

Schelling's thought in the main has been neglected, especially in the English-speaking world. An important factor in this was the ascendancy of Hegel, whose mature works portray Schelling as a mere footnote in the development of idealism. Schelling's ''Naturphilosophie'' also has been attacked by scientists for its tendency to analogize and lack of empirical orientation. However, some later philosophers have shown interest in re-examining Schelling's body of work.

Life

Early life

Schelling was born in the town of Leonberg in the Duchy of Württemberg (now Baden-Württemberg), the son of Joseph Friedrich Schelling and Gottliebin Marie. He attended the monastic school at Bebenhausen, near Tübingen, where his father was chaplain and an Orientalist professor. From 1783 to 1784 Schelling attended a Latin school in Nürtingen and knew Friedrich Hölderlin, who was five years his senior. On 18 October 1790, at the age of 15, he was granted permission to enroll at the Tübinger Stift (seminary of the Evangelical-Lutheran Church in Württemberg), despite not having yet reached the normal enrollment age of 20. At the Stift, he shared a room with Hegel as well as Hölderlin, and the three became good friends.

Schelling studied the Church fathers and ancient Greek philosophers. His interest gradually shifted from Lutheran theology to philosophy. In 1792 he graduated with his master's thesis, titled ''Antiquissimi de prima malorum humanorum origine philosophematis Genes. III. explicandi tentamen criticum et philosophicum'', and in 1795 he finished his doctoral thesis, titled ''De Marcione Paulinarum epistolarum emendatore'' (''On Marcion as emendator of the Pauline letters'') under Gottlob Christian Storr. Meanwhile, he had begun to study Kant and Fichte, who influenced him greatly. Representative of Schelling´s early period is also a discourse between him and the philosophical writer , who was Fichte´s housemate at that time, in letters and in Fichte´s Journal (1796/97) on ''interaction'', ''the pragmatic'' and Leibniz.

In 1797, while tutoring two youths of an aristocratic family, he visited Leipzig as their escort and had a chance to attend lectures at Leipzig University, where he was fascinated by contemporary physical studies including chemistry and biology. He also visited Dresden, where he saw collections of the Elector of Saxony, to which he referred later in his thinking on art. On a personal level, this Dresden visit of six weeks from August 1797 saw Schelling meet the brothers August Wilhelm Schlegel and Karl Friedrich Schlegel and his future wife Caroline (then married to August Wilhelm), and Novalis.

Jena period

After two years tutoring, in October 1798, at the age of 23, Schelling was called to University of Jena as an extraordinary (i.e., unpaid) professor of philosophy. His time at Jena (1798–1803) put Schelling at the centre of the intellectual ferment of Romanticism. He was on close terms with Johann Wolfgang von Goethe, who appreciated the poetic quality of the ''Naturphilosophie'', reading ''Von der Weltseele''. As the prime minister of the Duchy of Saxe-Weimar, Goethe invited Schelling to Jena. On the other hand, Schelling was unsympathetic to the ethical idealism that animated the work of Friedrich Schiller, the other pillar of Weimar Classicism. Later, in Schelling's ''Vorlesung über die Philosophie der Kunst'' (''Lecture on the Philosophy of Art'', 1802/03), Schiller's theory on the sublime was closely reviewed.

In Jena, Schelling was on good terms with Fichte at first, but their different conceptions, about nature in particular, led to increasing divergence. Fichte advised him to focus on transcendental philosophy: specifically, Fichte's own ''Wissenschaftlehre''. But Schelling, who was becoming the acknowledged leader of the Romantic school, rejected Fichte's thought as cold and abstract.

Schelling was especially close to August Wilhelm Schlegel and his wife, Caroline. A marriage between Schelling and Caroline's young daughter, Auguste Böhmer, was contemplated by both. Auguste died of dysentery in 1800, prompting many to blame Schelling, who had overseen her treatment. Robert Richards, however, argues in his book ''The Romantic Conception of Life'' that Schelling's interventions were most likely irrelevant, as the doctors called to the scene assured everyone involved that Auguste's disease was inevitably fatal. Auguste's death drew Schelling and Caroline closer. Schlegel had moved to Berlin, and a divorce was arranged with Goethe's help. Schelling's time at Jena came to an end, and on 2 June 1803 he and Caroline were married away from Jena. Their marriage ceremony was the last occasion Schelling met his school friend the poet Friedrich Hölderlin, who was already mentally ill at that time.

In his Jena period, Schelling had a closer relationship with Hegel again. With Schelling's help, Hegel became a private lecturer (''Privatdozent'') at Jena University. Hegel wrote a book titled ''Differenz des Fichte'schen und Schelling'schen Systems der Philosophie'' (''Difference between Fichte's and Schelling's Systems of Philosophy'', 1801), and supported Schelling's position against his idealistic predecessors, Fichte and Karl Leonhard Reinhold. Beginning in January 1802, Hegel and Schelling published the ''Kritisches Journal der Philosophie'' (''Critical Journal of Philosophy'') as co-editors, publishing papers on the philosophy of nature, but Schelling was too busy to stay involved with the editing and the magazine was mainly Hegel's publication, espousing a thought different from Schelling's. The magazine ceased publication in the spring of 1803 when Schelling moved from Jena to Würzburg.

Move to Würzburg and personal conflicts

After Jena, Schelling went to Bamberg for a time, to study Brunonian medicine (the theory of John Brown) with and Andreas Röschlaub. From September 1803 until April 1806 Schelling was professor at the new University of Würzburg. This period was marked by considerable flux in his views and by a final breach with Fichte and Hegel.

In Würzburg, a conservative Catholic city, Schelling found many enemies among his colleagues and in the government. He moved then to Munich in 1806, where he found a position as a state official, first as associate of the Bavarian Academy of Sciences and Humanities and secretary of the Royal Academy of Fine Arts, afterwards as secretary of the Philosophische Klasse (philosophical section) of the Academy of Sciences. 1806 was also the year Schelling published a book in which he criticized Fichte openly by name. In 1807 Schelling received the manuscript of Hegel's ''Phaenomenologie des Geistes'' (''Phenomenology of the Spirit'' or ''Mind''), which Hegel had sent to him, asking Schelling to write the foreword. Surprised to find critical remarks directed at his own philosophical theory, Schelling wrote back, asking Hegel to clarify whether he had intended to mock Schelling's followers who lacked a true understanding of his thought, or Schelling himself. Hegel never replied. In the same year, Schelling gave a speech about the relation between the visual arts and nature at the Academy of Fine Arts; Hegel wrote a severe criticism of it to one of his friends. After that, they criticized each other in lecture rooms and in books publicly until the end of their lives.

Munich period

Without resigning his official position in Munich, he lectured for a short time in Stuttgart (''Stuttgarter Privatvorlesungen'' tuttgart private lectures 1810), and seven years at the University of Erlangen (1820–1827). In 1809 Karoline died, just before he published ''Freiheitsschrift'' (''Freedom Essay'') the last book published during his life. Three years later, Schelling married one of her closest friends, Pauline Gotter, in whom he found a faithful companion.

During the long stay in Munich (1806–1841) Schelling's literary activity came gradually to a standstill. It is possible that it was the overpowering strength and influence of the Hegelian system that constrained Schelling, for it was only in 1834, after the death of Hegel, that, in a preface to a translation by Hubert Beckers of a work by Victor Cousin, he gave public utterance to the antagonism in which he stood to the Hegelian, and to his own earlier, conception of philosophy. The antagonism certainly was not new; the 1822 Erlangen lectures on the history of philosophy expressed the same in a pointed fashion, and Schelling had already begun the treatment of mythology and religion which, in his view, constituted the true positive complements to the negative of logical or speculative philosophy.

Berlin period

Public attention was powerfully attracted by hints of a new system which promised something more positive, especially in its treatment of religion, than the apparent results of Hegel's teaching. The appearance of critical writings by David Friedrich Strauss, Ludwig Feuerbach, and Bruno Bauer, and the disunion in the Hegelian school itself, expressed a growing alienation from the then dominant philosophy. In Berlin, the headquarters of the Hegelians, this found expression in attempts to obtain officially from Schelling a treatment of the new system that he was understood to have in reserve. Its realization did not come about until 1841, when Schelling's appointment as Prussian privy councillor and member of the Berlin Academy, gave him the right, a right he was requested to exercise, to deliver lectures in the university. Among those in attendance at his lectures were Søren Kierkegaard (who said Schelling talked "quite insufferable nonsense" and complained that he did not end his lectures on time), Mikhail Bakunin (who called them "interesting but rather insignificant"), Jacob Burckhardt, Alexander von Humboldt (who never accepted Schelling's natural philosophy), future church historian Philip Schaff and Friedrich Engels (who, as a partisan of Hegel, attended to "shield the great man's grave from abuse"). The opening lecture of his course was attended by a large and appreciative audience. The enmity of his old foe, H. E. G. Paulus, sharpened by Schelling's success, led to surreptitious publication of a verbatim report of the lectures on the philosophy of revelation. Schelling did not succeed in obtaining legal condemnation and suppression of this piracy and he stopped delivering public lectures in 1845.

Works

In 1793 Schelling contributed to Heinrich Eberhard Gottlob Paulus's periodical ''Memorabilien''. His 1795 dissertation was ''De Marcione Paullinarum epistolarum emendatore'' (''On Marcion as emendator of the Pauline letters''). In 1794, Schelling published an exposition of Fichte's thought entitled ''Ueber die Möglichkeit einer Form der Philosophie überhaupt'' (''On the Possibility of a Form of Philosophy in General''). This work was acknowledged by Fichte himself and immediately earned Schelling a reputation among philosophers. His more elaborate work, ''Vom Ich als Prinzip der Philosophie, oder über das Unbedingte im menschlichen Wissen'' (''On Self as Principle of Philosophy, or on the Unrestricted in Human Knowledge'', 1795), while still remaining within the limits of the Fichtean idealism, showed a tendency to give the Fichtean method a more objective application, and to amalgamate Spinoza's views with it. He contributed articles and reviews to the ''Philosophisches Journal'' of Fichte and Friedrich Immanuel Niethammer, and threw himself into the study of physical and medical science. In 1795 Schelling published ''Philosophische Briefe über Dogmatismus und Kritizismus'' (''Philosophical Letters on Dogmatism and Criticism''), consisting of 10 letters addressed to an unknown interlocutor that presented both a defense and critique of the Kantian system.

Between 1796/97 there was written a seminal manuscript now known as the ''Das älteste Systemprogramm des deutschen Idealismus'' ("The Oldest Systematic Program of German Idealism"). It survives in Hegel's handwriting. First published in 1916 by Franz Rosenzweig, it was attributed to Schelling. It has also been claimed that Hegel or Hölderlin was the author.Kai Hammermeister, ''The German Aesthetic Tradition'', Cambridge University Press, 2002, p. 76.

In 1797, Schelling published the essay ''Neue Deduction des Naturrechts'' ("New Deduction of Natural Law"), which anticipated Fichte's treatment of the topic in ''Grundlage des Naturrechts'' (''Foundations of Natural Law''). His studies of physical science bore fruit in ''Ideen zu einer Philosophie der Natur'' (''Ideas Concerning a Philosophy of Nature'', 1797), and the treatise ''Von der Weltseele'' (''On the World-Soul'', 1798). In ''Ideen'' Schelling referred to Leibniz and quoted from his '' Monadology''. He held Leibniz in high regard because of his view of nature during his natural philosophy period.

In 1800 Schelling published ''System des transcendentalen Idealismus'' ('' System of Transcendental Idealism''). In this book Schelling described transcendental philosophy and nature philosophy as complementary to one another. Fichte reacted by stating that Schelling's argument was unsound: in Fichte's theory nature as Not-Self (''Nicht-Ich'' = object) could not be a subject of philosophy, whose essential content is the subjective activity of the human intellect. The breach became unrecoverable in 1801 after Schelling published ''Darstellung des Systems meiner Philosophie'' ("Presentation of My System of Philosophy"). Fichte thought this title absurd since, in his opinion, philosophy could not be personalized. Moreover, in this book Schelling publicly expressed his estimation of Spinoza, whose work Fichte had repudiated as dogmatism, and declared that nature and spirit differ only in their quantity, but are essentially identical. According to Schelling, the absolute was the indifference to identity, which he considered to be an essential philosophical subject.

The "Aphorismen über die Naturphilosophie" ("Aphorisms on Nature Philosophy"), published in the ''Jahrbücher der Medicin als Wissenschaft'' (1805–1808), are for the most part extracts from the Würzburg lectures, and the ''Denkmal der Schrift von den göttlichen Dingen des Herrn Jacobi'' ("Monument to the Scripture of the Divine Things of Mr. Jacobi") was a response to an attack by Jacobi (the two accused each other of atheism). A work of significance is the 1809 ''Philosophische Untersuchungen über das Wesen der menschlichen Freiheit und die damit zusammenhängenden Gegenstände'' ('' Philosophical Inquiries into the Essence of Human Freedom''), which elaborates, with increasing mysticism, on ideas in the 1804 work ''Philosophie und Religion'' (''Philosophy and Religion''). However, in a change from the Jena period, evil is not an appearance coming from quantitative differences between the real and the ideal, but is something substantial. This work clearly paraphrased Kant's distinction between intelligible and empirical character. Schelling himself called freedom "a capacity for good and evil".

The 1815 essay ''Ueber die Gottheiten zu Samothrake'' ("On the Divinities of Samothrace") was ostensibly a part of a larger work, ''Weltalter'' ("The Ages of the World"), frequently announced as ready for publication, but of which little was ever written. Schelling planned ''Weltalter'' as a book in three parts, describing the past, present, and future of the world; however, he began only the first part, rewriting it several times and at last keeping it unpublished. The other two parts were left only in planning. Christopher John Murray describes the work as follows:

Building on the premise that philosophy cannot ultimately explain existence, he merges the earlier philosophies of Nature and identity with his newfound belief in a fundamental conflict between a dark unconscious principle and a conscious principle in God. God makes the universe intelligible by relating to the ground of the real but, insofar as nature is not complete intelligence, the real exists as a lack within the ideal and not as reflective of the ideal itself. The three universal ages – distinct only to us but not in the eternal God – therefore comprise a beginning where the principle of God before God is divine will striving for being, the present age, which is still part of this growth and hence a mediated fulfillment, and a finality where God is consciously and consummately Himself to Himself.

No authentic information on Schelling's new positive philosophy (''positive Philosophie'') was available until after his death at Bad Ragatz, on 20 August 1854. His sons then issued four volumes of his Berlin lectures: vol. i. ''Introduction to the Philosophy of Mythology'' (1856); ii. ''Philosophy of Mythology'' (1857); iii. and iv. ''Philosophy of Revelation'' (1858).

Periodization

Schelling, at all stages of his thought, called to his aid outward forms of some other system. Fichte, Spinoza, Jakob Boehme and the mystics, and finally, major Greek thinkers with their Neoplatonic, Gnostic, and Scholastic commentators, give colouring to particular works. In Schelling's own view, his philosophy fell into three stages. These were:
#Transition from Fichte's philosophy to a more objective conception of nature (an advance to ''Naturphilosophie'')
#Formulation of the identical, indifferent, absolute substratum of both nature and spirit (''Identitätsphilosophie'').
#Opposition of negative and positive philosophy, which was the theme of his Berlin lectures, though the concepts can be traced back to 1804.

''Naturphilosophie''

The function of Schelling's ''Naturphilosophie'' is to exhibit the ideal as springing from the real. The change which experience brings before us leads to the conception of duality, the polar opposition through which nature expresses itself. The dynamic series of stages in nature are matter (as the equilibrium of the fundamental expansive) and contractive forces (light, with its subordinate processes of magnetism, electricity, and chemical action) and organism (with its component phases of reproduction, irritability and sensibility).

Reputation and influence

Some scholars characterize Schelling as a protean thinker who, although brilliant, jumped from one subject to another and lacked the synthesizing power needed to arrive at a complete philosophical system. Others challenge the notion that Schelling's thought is marked by profound breaks, instead arguing that his philosophy always focused on a few common themes, especially human freedom, the absolute, and the relationship between spirit and nature. Unlike Hegel, Schelling did not believe that the absolute could be known in its true character through rational inquiry alone.

Schelling is still studied, although his reputation has varied over time. His work impressed the English romantic poet and critic Samuel Taylor Coleridge, who introduced his ideas into English-speaking culture, sometimes without full acknowledgment, as in the ''Biographia Literaria''. Coleridge's critical work was influential, and it was he who introduced into English literature Schelling's concept of the unconscious. Schelling's '' System of Transcendental Idealism'' has been seen as a precursor of Sigmund Freud's ''Interpretation of Dreams'' (1899).

Up to 1950, Schelling was almost a forgotten philosopher even in Germany. In the 1910s and 1920s, philosophers of neo-Kantianism and neo-Hegelianism, like Wilhelm Windelband or Richard Kroner, tended to describe Schelling as an episode connecting Fichte and Hegel. His late period tended to be ignored, and his philosophies of nature and of art in the 1790s and first decade of the 19th century were the main focus. In this context Kuno Fischer characterized Schelling's early philosophy as "aesthetic idealism", focusing on the argument where he ranked art as "the sole document and the eternal organ of philosophy" (''das einzige wahre und ewige Organon zugleich und Dokument der Philosophie''). From socialist philosophers like György Lukács, he was regarded as anachronistic. An exception was Martin Heidegger, who found in Schelling's ''On Human Freedom'' central themes of Western ontology - being, existence, and freedom - and expounded on them in his 1936 lectures.

In the 1950s, the situation began to change. In 1954, the centennial of his death, an international conference on Schelling was held. Several philosophers, including Karl Jaspers, gave presentations about the uniqueness and relevance of his thought, the interest shifting toward his later work on the origin of existence. Schelling was the subject of Jürgen Habermas's 1954 dissertation.

In 1955 Jaspers published ''Schelling'', representing him as a forerunner of the existentialists and Walter Schulz, one of organizers of the 1954 conference, published "Die Vollendung des Deutschen Idealismus in der Spätphilosophie Schellings" ("The Perfection of German Idealism in Schelling's Late Philosophy") claiming that Schelling had made German idealism complete with his late philosophy, particularly with his Berlin lectures in the 1840s. Schulz presented Schelling as the person who resolved the philosophical problems which Hegel had left incomplete, in contrast to the contemporary idea that Schelling had been surpassed by Hegel much earlier. Theologian Paul Tillich wrote: "what I learned from Schelling became determinative of my own philosophical and theological development". Maurice Merleau-Ponty likened his own project of natural ontology to Schelling's in his 1957–58 Course on Nature.

In the 1970s nature was again of interest to philosophers in relation to environmental issues. Schelling's philosophy of nature, particularly his intention to construct a program which covers both nature and the intellectual life in a single system and method, and restore nature as a central theme of philosophy, has been reevaluated in the contemporary context. His influence and relation to the German art scene, particularly to Romantic literature and visual art, has been an interest since the late 1960s, from Philipp Otto Runge to Gerhard Richter and Joseph Beuys. This interest has been revived in recent years through the work of the environmental philosopher Arran Gare who has identified a tradition of Schellingian science overcoming the opposition between science and the humanities, and offering the basis for an understanding of ecological science and ecological philosophy.

In relation to psychology, Schelling was considered to have coined the term " unconsciousness". Slavoj Žižek has written two books attempting to integrate Schelling's philosophy, mainly his middle period works including ''Weltalter'', with work of Jacques Lacan. The opposition and division in God and the problem of evil in God examined by the later Schelling influenced Luigi Pareyson's thought. Ken Wilber places Schelling as one of two philosophers who "after Plato, had the broadest impact on the Western mind".
