Jouffroy, Amédée Jacques, Sir James Mackintosh, Thomas Brown and others. It is said, for example, that Clarke made virtue consist in conformity to the relations of things universally, although the whole tenor of his argument shows him to have had in view conformity to such relations only as belong to the sphere of moral agency. It is true that he might have emphasized the relation of moral fitness to the will, and in this respect J. F. Herbart (q.v.) improved on Clarke’s statement of the case. To say, however, that Clarke simply confused mathematics and morals by justifying the moral criterion on a mathematical basis is a mistake. He compared the two subjects for the sake of the analogy.
Though Clarke can thus be defended against this and similar criticism, his work as a whole can be regarded only as an attempt to present the doctrines of the Cartesian school in a form which would not shock the conscience of his time. His work contained a measure of rationalism sufficient to arouse the suspicion of orthodox theologians, without making any valuable addition to, or modification of, the underlying doctrine.

CLARKE, THOMAS SHIELDS (1860– ), American artist, was born in Pittsburg, Pennsylvania, on the 25th of April 1860, and graduated at Princeton in 1882. He was a pupil of the Art Students’ League, New York, and of the École des Beaux Arts, Paris, under J. L. Gérôme; later he entered the atelier of Dagnan-Bouveret, and, becoming interested in sculpture, worked for a while under Henri M. Chapu. As a sculptor, he received a medal of honour in Madrid for his “The Cider Press,” now in the Golden Gate Park, San Francisco, California, and he made four caryatides of “The Seasons” for the Appellate Court House, New York. He designed an “Alma Mater” for Princeton University, and a model is in the library. Among his paintings are his “Night Market in Morocco” (Philadelphia Art Club), for which he received a medal at the International Exposition in Berlin in 1891, and his “A Fool’s Fool,” exhibited at the Salon in 1887 and now in the collection of the Pennsylvania Academy of Fine Arts, Philadelphia.
CLARKE, WILLIAM BRANWHITE (1798–1878), British geologist, was born at East Bergholt, in Suffolk, on the 2nd of June 1798. He received his early education at Dedham grammar school, and in 1817 entered Jesus College, Cambridge; he took his B.A. in 1821, was ordained and became M.A. in 1824. In 1821 he was appointed curate of Ramsholt in Suffolk, and he acted in his clerical capacity in other places until 1839. Having become interested in geology through the teachings of Sedgwick, he utilized his opportunities and gathered many interesting facts on the geology of East Anglia which were embodied in a paper “On the Geological Structure and Phenomena of Suffolk” (Trans. Geol. Soc. 1837). He also communicated a series of papers on the geology of S.E. Dorsetshire to the Magazine of Nat. Hist. (1837–1838). In 1839, after a severe illness, he left England for New South Wales, mainly with the object of benefiting by the sea voyage. He remained, however, in that country, and came to be regarded as the “Father of Australian Geology.” From the date of his arrival in New South Wales until 1870 he was in clerical charge first of the country from Paramatta to the Hawkesbury river, then of Campbelltown, and finally of Willoughby. He zealously devoted attention to the geology of the country, with results that have been of paramount importance. In 1841 he discovered gold, being the first explorer who had obtained it in situ in the country, finding it both in the detrital deposits and in the quartzites of the Blue Mountains, and he then declared his belief in its abundance. In 1849 he made the first actual discovery of tin in Australia and in 1859 he made known the occurrence of the diamond. He was also the first to indicate the presence of Silurian rocks, and to determine the age of the coal-bearing rocks in New South Wales. In 1869 he announced the discovery of remains of Dinornis in Queensland. He was a trustee of the Australian museum at Sydney, and an active member of the Royal Society of New South Wales. In 1860 he published Researches in the Southern Gold-fields of New South Wales. He was elected F.R.S. in 1876, and in the following year was awarded the Murchison medal by the Geological Society of London. His contributions to Australian scientific journals were numerous. He died near Sydney, on the 17th of June 1878.
CLARKSON, THOMAS (1760–1846), English anti-slavery agitator, was born on the 28th of March 1760, at Wisbeach, in Cambridgeshire, where his father was headmaster of the free grammar school. He was educated at St Paul’s school and at St John’s College, Cambridge. Having taken the first place among the middle bachelors as Latin essayist, he succeeded in 1785 in gaining a similar honour among the senior bachelors. The subject appointed by the vice-chancellor, Dr Peckhard, was one in which he was himself deeply interested—Anne liceat invitos in servitutem dare? (Is it right to make men slaves against their will?). In preparing for this essay Clarkson consulted a number of works on African slavery, of which the chief was Benezet’s Historical Survey of New Guinea; and the atrocities of which he read affected him so deeply that he determined to devote all his energies to effect the abolition of the slave trade, and gave up his intention of entering the church.
His first measure was to publish, with additions, an English translation of his prize essay (June 1786). He then commenced to search in all quarters for information concerning slavery. He soon discovered that the cause had already been taken up to some extent by others, most of whom belonged to the Society of Friends, and among the chief of whom were William Dillwyn, Joseph Wood and Granville Sharp. With the aid of these gentlemen, a committee of twelve was formed in May 1787 to do all that was possible to effect the abolition of the slave trade. Meanwhile Clarkson had also gained the sympathy of Wilberforce, Whitbread, Sturge and several other men of influence. Travelling from port to port, he now commenced to collect a large mass of evidence; and much of it was embodied in his Summary View of the Slave Trade, and the Probable Consequences of its Abolition, which, with a number of other anti-slavery tracts, was published by the committee. Pitt, Grenville, Fox and Burke looked favourably on the movement; in May 1788 Pitt introduced a parliamentary discussion on the subject, and Sir W. Dolben brought forward a bill providing that the number of slaves carried in a vessel should be proportional to its tonnage. A number of Liverpool and Bristol merchants obtained permission from the House to be heard by council against the bill, but on the 18th of June it passed the Commons. Soon after Clarkson published an Essay on the Impolicy of the Slave Trade; and for two months he was continuously engaged in travelling that he might meet men who were personally acquainted with the facts of the trade. From their lips he collected a considerable amount of evidence; but only nine could be prevailed upon to promise to appear before the privy council. Meanwhile other witnesses had been obtained by Wilberforce and the committee, and on the 12th of May 1789 the former led a debate on the subject in the House of Commons, in which he was seconded by Burke and supported by Pitt and Fox.
It was now the beginning of the French Revolution, and in the hope that he might arouse the French to sweep away slavery with other abuses, Clarkson crossed to Paris, where he remained six months. He found Necker head of the government, and obtained from him some sympathy but little help. Mirabeau, however, with his assistance, prepared a speech against slavery, to be delivered before the National Assembly, and the Marquis de la Fayette entered enthusiastically into his views. During this visit Clarkson met a deputation of negroes from Santo Domingo, who had come to France to present a petition to the National Assembly, desiring to be placed on an equal footing with the whites; but the storm of the Revolution permitted no substantial success to be achieved. Soon after his return home he engaged in a search, the apparent hopelessness of which finely displays his unshrinking laboriousness and his passionate
