Junghuhn (Franz Wilhelm), traveller and naturalist, b. Mansfeld, Prussia 29 Oct 1812. His father was a barber and surgeon. Franz studied at Halle and Berlin. He distinguished himself by love for botany and geology. In a duel with another student he killed him and was sentenced to imprisonment at Ehrenbreitster for 20 years. There he simulated madness and was removed to the asylum at Coblentz, whence he escaped to Algiers. In ’34 he joined the Dutch Army in the Malay Archipelago. He travelled through the island of Java making a botanical and geological survey. In ’54 he published his Licht en Schaduwbeelden uit de binnenlanden van Java (Light and Shadow pictures from the interior of Java), which contains his ideas of God, religion and science, together with sketches of nature and of the manners of the inhabitants. This book aroused much indignation from the pious, but also much agreement among freethinkers, and led to the establishment of De Dageraad (The Daybreak,) the organ of the Dutch Freethinkers Union. Junghuhn afterwards returned to Java and died 21 April, ’64 at Lemberg, Preanges, Regentsch. His Light and Shadow pictures have been several times reprinted.

Kalisch (Moritz Marcus), Ph.D., b. of Jewish parents in Pomerania, 16 May, 1828. Educated at the University of Berlin, where he studied under Vatke and others. Early in ’49 he came to England as a political refugee, and found employment as tutor to the Rothschild family. His critical Commentary on the Pentateuch commenced with a volume on Exodus, ’55, Genesis ’58, Leviticus in two vols. in ’67 and ’72 respectively. His rational criticism anticipated the school of Wellhausen. He published Bible Studies on Balaam and Jonah ’77, and discussions on philosophy and religion in a very able and learned work entitled Path and Goal, ’80. Kalisch also contributed to Scott’s series of Freethought tracts. Died at Baslow, Derbyshire, 23 Aug. 1885.

Kant (Immanuel), German critical philosopher, b. Königsberg, 22 April, 1724. He became professor of mathematics in 1770. In 1781 he published his great work, The Critick of Pure Reason, which denied all knowledge of the “Thing itself,” and overthrew the dogmatism of earlier metaphysics. In 1792 the philosopher fell under the royal censorship for his Religion within the Limits of Pure Reason. Kant effected a complete revolution in philosophy, and his immediate influence is not yet exhausted. Died at Königsberg, 12 Feb. 1804.

Kapila. One of the earliest Hindu thinkers. His system is known as the Atheistic philosophy. It is expounded in the Sankhya Karika, an important relic of bold rationalistic Indian thought. His aphorisms have been translated by J. R. Ballantyne.

Karneades. See [Carneades].

Keeler (Bronson C.) American author of an able Short History of the Bible, being a popular account of the formation and development of the canon, published at Chicago 1881.

Keim (Karl Theodor), German rationalist, b. Stuttgart, 17 Dec. 1825. Was educated at Tübingen, and became professor of theology at Zürich. Is chiefly known by his History of Jesus of Nazara (’67–’72). He also wrote a striking work on Primitive Christianity (’78), and endeavored to reproduce the lost work of Celsus. His rationalism hindered his promotion, and he was an invalid most of his days. Died at Giessen, where he was professor, 17 Nov. 1878.

Keith (George), Lord Marshall, Scotch soldier, b. Kincardine 1685, was appointed by Queen Anne captain of Guard. His property being confiscated for aiding the Pretender, he went to the Continent, and like his brother, was in high favor with Frederick the Great. Died Berlin, 25 May, 1778.

Keith (James Francis Edward), eminent military commander, b. Inverugie, Scotland, 11 June, 1696. Joined the army of the Pretender and was wounded at Sheriffmuir, 1715. He afterwards served with distinction in Spain and in Russia, where he rose to high favor under the Empress Elizabeth. In 1747 he took service with Frederick the Great as field-marshal, and became Governor of Berlin. Carlyle calls him “a very clear-eyed, sound observer of men and things. Frederick, the more he knows him, likes him the better.” From their correspondence it is evident Keith shared the sceptical opinions of Frederick. After brilliant exploits in the seven years’ war at Prague, Rossbach, and Olmutz, Marshal Keith fell in the battle of Hochkirch, 14 Oct. 1758.
