It has generally been taken for granted that he died a Buddhist; he emphatically declared, during the last year of his life, that he subscribed to no Buddhistical tenets.
Invariably the best critic of his own nature--"Truly we have no permanent opinions," he writes, "until our mental growth is done. The opinions we have are simply lent us for awhile by the gods--at compound interest!"
There is a characteristic anecdote told of him by a cousin who went to visit him when a boy at Ushaw. He asked her to bow to the figure of the Virgin Mary, which stood upon the stairway. She refused, upon which he earnestly repeated his request. Shortly after this incident he volunteered the statement to one of the college tutors, who found him lying on his back in the grass, looking up at the sky, that he was a pantheist.
After he had been reading some of the Russian novelists, though he confessed to a world of romance in old Romanism, the Greek Church, he thought, had a better chance of life. Russia seemed the coming race, a Russian Mass would one day be sung in St. Peter's, and Cossack soldiers would wait at Stamboul in the reconsecrated Basilica of Justinian for the apparition of that phantom priest destined to finish the Mass, interrupted by the swords of the Janizaries of Mahomet II.
In spite of frequently declaring himself a radical, the trend of Hearn's mind was distinctly conservative. Old beliefs handed down from century to century, old temples sanctified for generations, old emotions that had moulded the life of the people, had for him supreme attraction. When he arrived at Matsue and found an Arcadian state of things, a happy, contented, industrious people, and an artistic development of a remarkable kind, the girl he married, also, Setsu Koizumi, having been brought up in the tenets of the ancient faith, it was a foregone conclusion that he should endeavour to harmonise Shintoism and Buddhism with the philosophy propounded by his high-priest, Herbert Spencer. Following the lead of his master, he committed himself to the statement that "ancestor worship was the root of all religion." Cut off from communication with outside opinion, he did not know how hotly this idea had been contested, Frederic Harrison, amongst others, asserting that the worship of natural objects--not spirit or ancestor worship--was the beginning of the religious sentiment in man.
