Hickok by Jack McCall. He is buried in Mount Moriah Cemetery, Deadwood. [Material in private collection of author is the prin- cipal source. G. A. Custer, Wild Life on the Plains (1874), E. B. Custer, Tenting on the Plains (1887) and Following the Guidon (1890) are reliable, but J. W. Buel, Heroes of the Plains (1882), and Frank J. Wil- stach, Wild Bill Hickok (1926) contain errors. G. W. Nichols' article in Harpers' New Monthly Mag., Feb. 1867, is good except for the account of the fight at Rock Creek Station, which Hickok repudiated as soon as he read it, saying he never told Nichols that story.

C HICKOK, LAURENS PERSEUS (Dec. 29, 1798-May 6, 1888), clergyman, philosopher, was born in Bethel, Conn., the son of Ebenezer and Polly (Benedict) Hickok. He graduated at Union College in 1820; studied theology under Rev. William Andrews of Danbury and Rev. Bennet Tyler \_q.v."\] was married on Oct. 9, 1822, to Elizabeth Benedict Taylor of Kent, Conn.; and was ordained and installed as pastor at Kent on Dec. 10,1823. There he remained for six years. At one time during his pastorate for- mal charges were brought of "unministerial con- duct, such as whistling, vaulting fences, running on the streets, and driving a fast horse" (Francis Atwater, History of Kent, Conn., 1897, p. 52), but the case against him was dismissed by the Consociation. On July 15, 1829, he became pas- tor of the church at Litchfield, Conn., where he remained until 1836. He was professor of Chris- tian theology in Western Reserve College, 1836- 44, and in Auburn Theological Seminary, 1844- 52. In the latter year he went to Union College as vice-president and professor of mental and moral philosophy. In 1856 he acted as moderator in the new-school Presbyterian General Assem- bly. During the declining years of President Nott of Union, Hickok carried most of the actual duties of the presidency, succeeding to the office in 1866. He resigned in 1868 to devote himself to his literary labors and passed the rest of his life in retirement at Amherst, Mass. He was a man of stalwart frame, massive head, robust health, and indomitable energy. Besides pub- lished sermons and addresses, he was the author of Rational Psychology (1849), A System of Moral Science (1853), Empirical Psychology (1854; rev. ed. 1882), Creator and Creation (1872), Rational Cosmology (1858), Humanity Immortal (1872), The Logic of Reason (1875). As a philosopher Hickok was unquestionably the ablest American dialectician of his day. Com- mitted by his training to a defense of the Chris- tian theology, he undertook this in no parochial spirit but was determined to base his theology Hickok on the firmest and broadest of rational founda- tions. "How much more rapidly," he wrote, "may the knowledge and worship of the true God spread, when philosophy herself shall become converted to, and baptized in, a Gospel theism!" (Rational Cosmology, p. 53), To the task of con- verting modern philosophy to theism he brought a keen and subtle intellect, scornful of any aid from mysticism, confident in the power of rea- son to advance by serried arguments to the con- quest of absolute knowledge. The terms of his problem were set for him by Kant's Critique of Pure Reason, whose significance he understood better than did his theological contemporaries. He saw the folly of reverting, like McCosh, Por- ter, and Hopkins, to the pre-Kantian position of naive realism; advance along the lines of the German idealists would lead to pantheism; while to remain within the negative conclusions of the first Critique itself would be to accept a still more abhorrent skepticism. In his earliest and most important work, Rational Psychology, which was the first profound treatment of epistemology that had come from any American pen since Jonathan Edwards, Hickok analyzed the entire process of knowledge, endeavoring to reach a priori prin- ciples free from the subjectivity of the Kantian categories. The resultant philosophy, which he called "Constructive Realism," stressed the "con- structive" powers of the mind so far that the "realism" was seriously endangered. Accepting the current distinction between the faculties of the sensibility, understanding, and reason, he credited the reason with an intuitive insight of "comprehension" altogether different from the discursive procedure of the understanding. In the light of reason thus conceived, he argued for the being of God and the individual soul as su- pernatural forces: the existence of nature as a whole could only be explained as the creation of a power not itself a part of nature; knowledge of phenomena as phenomena could only be valid for a knower who is not himself a phenomenon. In his System of Moral Science Hickok applied the same principles to the field of ethics and ar- gued that the facts of the moral life require and demonstrate the reality of the individual soul as a free agent His ethical views were rigoristic and largely Kantian. In his Rational Cosmology he expounded the a priori principles according to which the universe must have been created and also showed with much ingenuity that as a mat- ter of scientific fact it was actually created as it must have been. In this excursion into physics he came dangerously near to falling into the maw of pantheism, always gaping uncomfortably near his theism.
