GERSONIDES, or Ben Gerson (Gershon), LEVI, known also as Ralbag (1288-1344), Jewish philosopher and commentator, was born at Bagnols in Languedoc, probably in 1288. As in the case of the other medieval Jewish philosophers little is known of his life. His family had been distinguished for piety and exegetical skill, but though he was known in the Jewish community by commentaries on certain books of the Bible, he never seems to have accepted any rabbinical post. Possibly the freedom of his opinions may have put obstacles in the way of his preferment. He is known to have been at Avignon and Orange during his life, and is believed to have died in 1344, though Zacuto asserts that he died at Perpignan in 1370. Part of his writings consist of commentaries on the portions of Aristotle then known, or rather of commentaries on the commentaries of Averroes. Some of these are printed in the early Latin editions of Aristotle’s works. His most important treatise, that by which he has a place in the history of philosophy, is entitled Milḥamoth ’Adonai (The Wars of God), and occupied twelve years in composition (1317-1329). A portion of it, containing an elaborate survey of astronomy as known to the Arabs, was translated into Latin in 1342 at the request of Clement VI. The Milḥamoth is throughout modelled after the plan of the great work of Jewish philosophy, the Moreh Nebuhīm of Moses Maimonides, and may be regarded as an elaborate criticism from the more philosophical point of view (mainly Averroistic) of the syncretism of Aristotelianism and Jewish orthodoxy as presented in that work. The six books pass in review (1) the doctrine of the soul, in which Gersonides defends the theory of impersonal reason as mediating between God and man, and explains the formation of the higher reason (or acquired intellect, as it was called) in humanity,—his view being thoroughly realist and resembling that of Avicebron; (2) prophecy; (3) and (4) God’s knowledge of facts and providence, in which is advanced the curious theory that God does not know individual facts, and that, while there is general providence for all, special providence only extends to those whose reason has been enlightened; (5) celestial substances, treating of the strange spiritual hierarchy which the Jewish philosophers of the middle ages accepted from the Neoplatonists and the pseudo-Dionysius, and also giving, along with astronomical details, much of astrological theory; (6) creation and miracles, in respect to which Gerson deviates widely from the position of Maimonides. Gersonides was also the author of a commentary on the Pentateuch and other exegetical and scientific works.

A careful analysis of the Milḥamoth is given in Rabbi Isidore Weil’s Philosophie religieuse de Lévi-Ben-Gerson (Paris, 1868). See also Munk, Mélanges de phil. juive et arabe; and Joel, Religionsphilosophie d. L. Ben-Gerson (1862). The Milḥamoth was published in 1560 at Riva di Trento, and has been published at Leipzig, 1866.

GERSOPPA, FALLS OF, a cataract on the Sharavati river in the North Kanara district of Bombay. The falls are considered the finest in India. The river descends in four separate cascades called the Raja or Horseshoe, the Roarer, the Rocket and the Dame Blanche. The cliff over which the river plunges is 830 ft. high, and the pool at the base of the Raja Fall is 132 ft. deep. The falls are reached by boat from Honavar, or by road from Gersoppa village, 18 m. distant. Near the village are extensive ruins (the finest of which is a cruciform temple) of Nagarbastikere, the capital of the Jain chiefs of Gersoppa. Their family was established in power in 1409 by the Vijayanagar kings, but subsequently became practically independent. The chieftaincy was several times held by women, and on the death of the last queen (1608) it collapsed, having been attacked by the chief of Bednur. Among the Portuguese the district was celebrated for its pepper, and they called its queen “Regina da pimenta” (queen of pepper).


GERSTÄCKER, FRIEDRICH (1816-1872), German novelist and writer of travels, was born at Hamburg on the 10th of May 1816, the son of Friedrich Gerstäcker (1790-1825), a celebrated opera singer. After being apprenticed to a commercial house he learnt farming in Saxony. In 1837, however, having imbibed from Robinson Crusoe a taste for adventure, he went to America and wandered over a large part of the United States, supporting himself by whatever work came to hand. In 1843 he returned to Germany, to find himself, to his great surprise, famous as an author. His mother had shown his diary, which he regularly sent home, and which contained descriptions of his adventures in the New World, to the editor of the Rosen, who published them in that periodical. These sketches having found favour with the public, Gerstäcker issued them in 1844 under the title Streif-und Jagdzüge durch die Vereinigten Staaten Nordamerikas. In 1845 his first novel, Die Regulatoren in Arkansas, appeared, and henceforth the stream of his productiveness flowed on uninterruptedly. From 1849 to 1852 Gerstäcker travelled round the world, visiting North and South America, Polynesia and Australia, and on his return settled in Leipzig. In 1860 he again went to South America, chiefly with a view to inspecting the German colonies there and reporting on the possibility of diverting the stream of German emigration in this direction. The result of his observations and experiences he recorded in Achtzehn Monate in Südamerika (1862). In 1862 he accompanied Duke Ernest of Saxe-Coburg-Gotha to Egypt and Abyssinia, and on his return settled at Coburg, where he wrote a number of novels descriptive of the scenes he had visited. In 1867-1868 Gerstäcker again undertook a long journey, visiting North America, Venezuela and the West Indies, and on his return lived first at Dresden and then at Brunswick, where he died on the 31st of May 1872. His genial and straightforward character made him personally beloved; and his works, dealing as they did with the great world hitherto hidden from the narrow “parochialism” of German life, obtained an immense popularity. This was not due to any graces of style, in which they are singularly lacking; but the unstudied freshness of the author’s descriptions, and his sturdy humour, appealed to the wholesome instincts of the public. Many of his books were translated into foreign languages, notably into English, and became widely known on both sides of the Atlantic. His best works, from a literary point of view, are, besides the above-mentioned Regulatoren, his Flusspiraten des Mississippi (1848); the novel Tahiti (1854); his Australian romance Die beiden Sträflinge (1857); Aus dem Matrosenleben (1857); and Blau Wasser (1858). His Travels exist in an English translation.

Gerstäcker’s Gesammelte Schriften were published at Jena in 44 vols. (1872-1879); a selection, edited by D. Theden in 24 vols. (1889-1890). See A. Karl, Friedrich Gerstäcker, der Weitgereiste. Ein Lebensbild (1873).
