Politics, religion, and philosophy

In broad terms, Dodgson has traditionally been regarded as politically, religiously, and personally conservative. Martin Gardner labels Dodgson as a Tory who was "awed by lords and inclined to be snobbish towards inferiors". William Tuckwell, in his Reminiscences of Oxford (1900), regarded him as "austere, shy, precise, absorbed in mathematical reverie, watchfully tenacious of his dignity, stiffly conservative in political, theological, social theory, his life mapped out in squares like Alice's landscape". Dodgson was ordained a deacon in the Church of England on 22 December 1861. In The Life and Letters of Lewis Carroll, the editor states that "his Diary is full of such modest depreciations of himself and his work, interspersed with earnest prayers (too sacred and private to be reproduced here) that God would forgive him the past, and help him to perform His holy will in the future." When a friend asked him about his religious views, Dodgson wrote in response that he was a member of the Church of England, but "doubt if he was fully a 'High Churchman ' ". He added:

I believe that when you and I come to lie down for the last time, if only we can keep firm hold of the great truths Christ taught us—our own utter worthlessness and His infinite worth; and that He has brought us back to our one Father, and made us His brethren, and so brethren to one another—we shall have all we need to guide us through the shadows. Most assuredly I accept to the full the doctrines you refer to—that Christ died to save us, that we have no other way of salvation open to us but through His death, and that it is by faith in Him, and through no merit of ours, that we are reconciled to God; and most assuredly I can cordially say, "I owe all to Him who loved me, and died on the Cross of Calvary."

Dodgson also expressed interest in other fields. He was an early member of the Society for Psychical Research, and one of his letters suggests that he accepted as real what was then called "thought reading". Dodgson wrote some studies of various philosophical arguments. In 1895, he developed a philosophical regressus-argument on deductive reasoning in his article " What the Tortoise Said to Achilles ", which appeared in one of the early volumes of Mind. The article was reprinted in the same journal a hundred years later in 1995, with a subsequent article by Simon Blackburn titled "Practical Tortoise Raising".
