 which enjoy a measure of self-government in certain specified respects.

In philosophy, the term (with its antithesis “heteronomy”) was applied by Kant to that aspect of the rational will in which, qua rational, it is a law to itself, independently alike of any external authority, of the results of experience and of the impulses of pleasure and pain. In the sphere of morals, the ultimate and only authority which the mind can recognize is the law which emerges from the pure moral consciousness. This is the only sense in which moral freedom can be understood. (See ; .) Though the term “autonomy” in its fullest sense implies entire freedom from causal necessity, it can also be used even in determinist theories for relative independence of particular conditions, theological or conventional.

AUTOPSY (Gr. , self, and  , sight, investigation), a personal examination, specifically a post-mortem (“after death”) examination of a dead body, to ascertain the cause of death, &c. The term “necropsy” (Gr. , corpse) is sometimes used in this sense. (See and .)

AUTRAN, JOSEPH (1813–1877), French poet, was born at Marseilles on the 20th of June 1813. In 1832 he addressed an ode to Lamartine, who was then at Marseilles on his way to the East. The elder poet persuaded the young man’s father to allow him to follow his poetic bent, and Autran remained from that time a faithful disciple of Lamartine. His best known work is La Mer (1835), remodelled in 1852 as Les Poèmes de la mer. Ludibria ventis (1838) followed, and the success of these two volumes gained for Autran the librarianship of his native town. His other most important work is his Vie rurale (1856), a series of pictures of peasant life. The Algerian campaigns inspired him with verses in honour of the common soldier. Milianah (1842) describes the heroic defence of that town, and in the same vein is his Laboureurs et soldats (1854). Among his other works are the Paroles de Salomon (1868), Épîtres rustiques (1861), Sonnets capricieux, and a tragedy played with great success at the Odéon in 1848, La Fille d’Eschyle. A definitive edition of his works was brought out between 1875 and 1881. He became a member of the French Academy in 1868, and died at Marseilles on the 6th of March 1877.

AUTUN, a town of east-central France, capital of an arrondissement in the department of Saône-et-Loire, 62 m. S.W. of Dijon on the Paris-Lyon railway to Nevers. Pop. (1906) 11,927. Autun is pleasantly situated on the slope of a hill at the foot of which runs the Arroux. Its former greatness is attested by many Roman remains, the chief of which are two well-preserved stone gateways, the Porte d’ Arroux and the Porte St André, both pierced with four archways and surmounted by arcades. There are also remains of the old ramparts and aqueducts, of a square tower called the Temple of Janus, of a theatre and of an amphitheatre. A pyramid in the neighbouring village of Couhard was probably a sepulchral monument. The chapel of St Nicolas (12th century) contains many of the remains discovered at Autun. The cathedral of St Lazare, once the chapel attached to the residence of the dukes of Burgundy, is in the highest part of the town. It belongs mainly to the 12th century, but the Gothic central tower and the chapels were added in the 15th century by Nicolas Rolin, chancellor of Burgundy, born at Autun. The chief artistic features of the church are the group of the Last Judgment sculptured on the tympanum above the west door, and the painting by Ingres representing the martyrdom of St Symphorien, which took place at Autun in 179. In the cathedral square stands the fountain of St Lazare, a work of the Renaissance. The hôtel Rolin, a house of the 15th century, contains the collections of the “Aeduan literary and scientific society.” The hôtel de ville, containing a museum of paintings, the law-court and the theatre are modern buildings. Autun is the seat of a bishopric, of tribunals of first instance and of commerce, and has an ecclesiastical seminary, a communal college and a cavalry school. Among the industries of the town are the extraction of oil from the bituminous schist obtained in the neighbourhood, leather manufacture, metal-founding, marble-working, and the manufacture of machinery and furniture. Autun is the commercial centre for a large part of the Morvan, and has considerable trade in timber and cattle.

Autun (Augustodunum) succeeded Bibracte as capital of the Aedui when Gaul was reorganized by Augustus. Under the Romans, it was a flourishing town, covering double its present extent and renowned for its schools of rhetoric. In the succeeding centuries its prosperity drew upon it the attacks of the barbarians, the Saracens and the Normans. The counts of Autun in 880 became dukes of Burgundy, and the town was the residence of the latter till 1276. It was ravaged by the English in 1379, and, in 1591, owing to its support of the League, had to sustain a siege conducted by Marshal Jean d’Aumont, general of Henry IV.

AUTUNITE, or, a mineral which is one of the “uranium micas,” differing from the more commonly occurring (q.v.) or cupro-uranite in containing calcium in place of copper. It is a hydrous uranium and calcium phosphate, Ca(UO2)2(PO4)2+8(or 12)H2O. Though closely resembling the tetragonal torbernite in form, it crystallizes in the orthorhombic system and is optically biaxial. The crystals have the shape of thin plates with very nearly square outline (89° 17′ instead of 90°). An important character is the perfect micaceous cleavage parallel to the basal plane, on which plane the lustre is pearly. The colour is sulphur-yellow, and this enables the mineral to be distinguished at a glance from the emerald-green torbernite. Hardness 2-2; specific gravity 3·05-3·19. Autunite is usually found with pitchblende and other uranium minerals, or with ores of silver, tin and iron; it sometimes coats joint-planes in gneiss and pegmatite. Falkenstein in Saxony, St Symphorien near Autun (hence the name of the species), and St Day in Cornwall are well-known localities for this mineral.

AUVERGNE, formerly a province of France, corresponding to the departments of Cantal and Puy-de-Dôme, with the arrondissement of Brioude in Haute-Loire. It contains many mountains volcanic in origin (Plomb du Cantal, Puy de Dôme, Mont Dore), fertile valleys such as that of Limagne, vast pasture-lands, and numerous medicinal springs. Up to the present day the population retains strongly-marked Celtic characteristics. In the time of Caesar the Arverni were a powerful confederation, the Arvernian Vercingetorix being the most famous of the Gallic chieftains who fought against the Romans. Under the empire Arvernia formed part of Prima Aquitania, and the district shared in the fortunes of Aquitaine during the Merovingian and Carolingian periods. Auvergne was the seat of a separate countship before the end of the 8th century; the first hereditary count was William the Pious (886). By the marriage of Eleanor of Aquitaine with Henry Plantagenet, the countship passed under the suzerainty of the kings of England, but at the same time it was divided, William VII., called the Young (1145–1168), having been despoiled of a portion of his domain by his uncle William VIII., called the Old, who was supported by Henry II. of England, so that he only retained the region bounded by the Allier and the Coux. It is this district that from the end of the 13th century was called the Dauphiné d’Auvergne. This family quarrel occasioned the intervention of Philip Augustus, king of France, who succeeded in possessing himself of a large part of the country, which was annexed to the royal domains under the name of Terre d’Auvergne. As the price of his concurrence with the king in this matter, the bishop of Clermont, Robert I. (1195–1227), was granted the lordship of the town of Clermont, which subsequently became a countship. Such was the origin of the four great historic lordships of Auvergne. The Terre d’Auvergne was first an appanage of Count Alphonse of Poitiers (1241–1271), and in 1360 was erected into a duchy in the peerage of France (duché-pairie) by King John II. in favour of his son John, through whose daughter the new title passed in 1416 to the house of Bourbon. The last duke, the celebrated constable Charles of Bourbon, united the domains of the Dauphiné to those of the
