I neither deny nor affirm the immortality of man. I see no reason for believing in it; but, on the other hand, I have no means of disproving it.
Pray understand that I have no à priori objections to the doctrine. No man who has to deal daily and hourly with nature can trouble himself about à priori difficulties. Give me such evidence as would justify me in believing anything else, and I will believe that. Why should I not? It is not half so wonderful as the conservation of force, or the indestructibility of matter. Whoso clearly appreciates all that is implied in the falling of a stone can have no difficulty about any doctrine simply on account of its marvellousness. But the longer I live the more obvious it is to me that the most sacred act of a man's life is to say and to feel, "I believe such and such to be true." All the greatest rewards, and all the heaviest penalties of existence, cling about that act. The universe is one and the same throughout; and if the condition of my success in unravelling some little difficulty of anatomy or physiology is that I shall rigorously refuse to put faith in that which does not rest on sufficient evidence, I cannot believe that the great mysteries of existence will be laid open to me on other terms. It is of no use to talk to me of analogies and probabilities. I know what I mean when I say I believe in the law of the inverse square, and I will not rest my life and my hopes upon weaker convictions. I dare not if I would.
From such a point of view intellectual veracity takes on a moral aspect; indeed, it is a pillar of morality. Disregard of it has led to incalculable social wrong and individual suffering, oppressions and persecutions, unprogressive obscurantism, joined with perverted ideals and intellectual arrest. "Ecrasez l'infâme," cried the reforming Voltaire; his "infamous" was very much this perverting influence, exaggerated and armed with power, which had made the great organization of the Roman Church in his time a monstrous instrument of autocratic tradition, cruel, rapacious, blindly intolerant, jealous of light and liberty. In England the growth of political liberty had deprived the darkest lights of the Church of almost all power for active interference in the administration of the State, though the pressure of traditionalism exercised itself less crudely, if scarce less surely, in the Universities, the Press, religious opinion, and the army of conventional respectability. So strong was it in social influence that a man, openly professing to make a guide of his reason instead of his parson, was liable to be pushed outside the pale.

VERACITY AND AGNOSTICISM
One of the most ticklish of all subjects to handle at this period was the position of the human species in zoological classification. "It was a burning question in the sense that those who touched it were almost certain to burn their fingers severely." In the fifties Sir William Lawrence had been well-nigh ostracized for his book On Man, "which now might be read in a Sunday-school without surprising anybody." When Huxley submitted the proofs of Man's Place in Nature to "a competent anatomist, and good friend of his," asking him, if he could, to point out any errors of fact, the friend—it was Lawrence himself—declared he could find none, but gave an earnest warning as to the consequences of publication. Here was one of the cases where Huxley's firm resolution applied—to speak out if necessary, regardless of consequences; indeed, he felt sure that all the evil things prophesied would not be so painful to him as the giving up that which he had resolved to do upon grounds which he conceived to be right. As he wrote later (in 1876):—
It seemed to me that a man of science has no raison d'être at all unless he is willing to face much greater risks than these for the sake of that which he believes to be true; and further, that to a man of science such risks do not count for much—they are by no means so serious as they are to a man of letters, for example.
The book was published, and the friend's forecast was amply justified.
The Boreas of criticism blew his hardest blasts of misrepresentation and ridicule for some years, and I was even as one of the wicked. Indeed, it surprises me at times to think how any one who had sunk so low could since have emerged into, at any rate, relative respectability. Personally, like the non-corvine personages in the Ingoldsby legend, I did not feel "one penny the worse." Translated into several languages, the book reached a wider public than I had ever hoped for; being largely helped, I imagine, by the Ernulphine advertisements to which I referred. It has had the honour of being freely utilized without acknowledgment by writers of repute; and, finally, it achieved the fate, which is the euthanasia of a scientific work, of being enclosed among the rubble of the foundations of later knowledge, and forgotten.
To my observation, human nature has not sensibly changed during the last thirty years. I doubt not that there are truths as plainly obvious, and as generally denied, as those contained in Man's Place in Nature, now awaiting enunciation. If there is a young man of the present generation who has taken as much trouble as I did to assure himself that they are truths, let him come out with them, without troubling his head about the barking of the dogs of St. Ernulphus. Veritas praevalebit—some day; and even if she does not prevail in his time, he himself will be all the better and wiser for having tried to help her. And let him recollect that such great reward is full payment for all his labour and pains.
