of, and wrote about, supernatural forces, particularly those that control the universe through indifference or caprice, a force he called The Immanent Will. He also showed in his writing some degree of fascination with ghosts and spirits. Even so, he retained a strong emotional attachment to the Christian liturgy and church rituals, particularly as manifested in rural communities, that had been such a formative influence in his early years, and Biblical references can be found woven throughout many of Hardy's novels. Hardy's friends during his apprenticeship to John Hicks included Horace Moule (one of the eight sons of Henry Moule), and the poet William Barnes, both ministers of religion. Moule remained a close friend of Hardy's for the rest of his life, and introduced him to new scientific findings that cast doubt on literal interpretations of the Bible, such as those of Gideon Mantell. Moule gave Hardy a copy of Mantell's book The Wonders of Geology (1848) in 1858, and Adelene Buckland has suggested that there are "compelling similarities" between the "cliffhanger" section from A Pair of Blue Eyes and Mantell's geological descriptions. It has also been suggested that the character of Henry Knight in A Pair of Blue Eyes was based on Horace Moule. Throughout his life, Hardy sought a rationale for believing in an afterlife or a timeless existence, turning first to spiritualists, such as Henri Bergson, and then to Albert Einstein and J. M. E. McTaggart, considering their philosophy on time and space in relation to immortality.

Influence Hardy corresponded with and visited Lady Catherine Milnes Gaskell at Wenlock Abbey and many of Lady Catherine's books are inspired by Hardy, who was very fond of her. D. H. Lawrence's Study of Thomas Hardy (1914, first published 1936) indicates the importance of Hardy for him, even though this work is a platform for Lawrence's own developing philosophy rather than a more standard literary study. The influence of Hardy's treatment of character, and Lawrence's own response to the central metaphysic behind many of Hardy's novels, helped significantly in the development of The Rainbow (1915) and Women in Love (1920).
