There was in this extraordinary man an unusual combination of the capacity of apprehending truth, with the ability to demonstrate and make it palpable to others. They often exist together in unequal degrees. Lord Mansfield's power of luminous explication was so surpassing that one might almost say that he made others perceive what he did not understand himself; but the numerous instances in which his decisions have been directly overthrown by his successors, and the still greater number of cases in which his opinions have been silently departed from, compel a belief that his judgment was not of the truest kind. Lord Eldon's judicial sagacity was a species of inspiration; but he seemed to be unable not only to convince others; but even to certify himself of the correctness of his own greatest and wisest determinations. But Judge Marshall's sense appeared to be at once both instinctive and analytical: his logic extended as far as his perception: he had no propositions in his thoughts which he could not resolve into their axioms. Truth came to him as a revelation, and from him as a demonstration. His mind was more than the faculty of vision; it was a body of light, which irradiated the subject to which it was directed, and rendered it as distinct to every other eye as it was to its own. The mental integrity of this illustrious man was not the least important element of his greatness. Those qualities of vanity, fondness for display, the love of effect, the solicitation of applause, sensibility to opinions, which are the immoralities of intellect, never attached to that stainless essence of pure reason. He seemed to men to be a passionless intelligence; susceptible to no feeling but the constant love of right; subject to no affection but a polarity toward truth. As has already been stated, the great chief justice was married when twenty-eight years of age, to Miss Ambler, of York, in Virginia; there have been few such unions in every respect more fortunate and delightful; the wife died but a short time before the husband, who, not more than two days previous to his own decease, directed that his body should be laid with hers, and that the plain stone to indicate the place of their rest should have only this simple inscription: "John Marshall, son of Thomas and Mary Marshall, was born on the 24th of September, 1755, intermarried with Mary Willis Ambler on the 3d of January, 1783, and departed this life the ---- day of ---- 18--." With no other alteration than the filling of the blanks, this is engraved on the modest white marble which is over their remains in the beautiful cemetery on Shoccoe Hill, of Richmond.
