This is due to the biographers: they dwell largely on the scientific achievement of a man, likewise on his human qualities, but his religion is often not mentioned at all. When, in 1888, a monument was erected to _Ampère_ in his native city, Lyons, not a word in the speeches referred to the fact that he was a faithful Catholic. Nay, more; on one of the books seen on his monument is chiselled in bold letters the word “Encyclopédie.” Those unaware of the facts would infer that _Ampère_ had been one of the Encyclopædists. His actual relation to this infamous work was that he had read it in his youth, but abhorred it in his later age. The English physicist, _Faraday_ (died 1867), according to _Tyndall_ and _Du Bois-Reymond_ the greatest experimentist of all times, was, like _Volta_ and _Ampère_, of religious mind. In a letter to a lady he wrote: “I belong to a small and despised Christian sect, known by the name of Sandemanians. Our hope is based upon the belief which is in Christ.” In 1847, he concluded his lectures at the Royal Institution with the following words: “In teaching us those things, our science should prompt us to think of Him whose works they are.” At a later lecture, he declared: “I have never encountered anything to cause a contradiction between things within the scope of man, and the higher things, relating to his future and unconceivable to (unaided) human mind” (_Jones_, The Life and Letters of Faraday). Of the same bent of mind was _Faraday’s_ fellow countryman, _Maxwell_ (died 1879), known to every one who has studied the development of the theories of electricity. This ingenious theoretician of electrics, professor of experimental physics at Cambridge, was deeply religious. Every evening he led in the family prayer; he regularly attended divine service, and partook of the monthly communion of his denomination. Those more intimately acquainted with _Maxwell_ agree, that he was one of the worthiest men they ever met. Nothing could better illustrate his religious sentiment than the splendid prayer found among his posthumous papers: “Almighty God, Thou who hast created man after Thy image and hast given him a living soul, that he should search Thee and rule over Thy creatures, teach us to study the works by Thy hands that we may subject the earth for our use, and strengthen our reason for Thy service, and let us receive Thy holy word thus, that we may believe in Him whom Thou hast sent us to give us the knowledge of salvation and the forgiving of our sins, all of which we pray for in the name of the same Jesus Christ, our Lord” (_Campbell-Garnett_, The Life of J. C. Maxwell). _Maxwell’s_ devout mind is especially significant here, because, like _Ampère_ and _Volta_, he occupied himself much with philosophical and theological questions. Every Sunday upon return from church he is said to have buried himself in his theological books.
