So strange did this precaution in speech seem in my time, that it was believed that reticence was not honest precaution, but prudent concealment of actual conviction, intended to evade orthodox anger. On problems relating to infinite existence and an unknown future, it requires infinite knowledge to give an affirmative answer. No one said he had infinite information, but everybody declaimed as though he had. It appeared not to have occurred to many that there was a state of the understanding in which lack of conviction was owing to lack of evidence. Where the desire to believe is hereditary, it is difficult to realise that there are questions upon which certainty may, to many minds, be unattainable, and that an honest man who felt this was bound to say so. An American journal, which needed forbearance from its readers for its own heresy, published the opinion that Huxley was a "dodger" in philosophy. Whereas Huxley was for integrity in thought and speech. He was for scientific accuracy as far as attainable. His own outspokenness was the glory of philosophy and science in his day. He never denied his convictions; he never apologised for them; he never explained them away. Is it over his noble tomb that we are to write, "Here lies a Dodger," because he invented an honest term to denote the measured knowledge of honest thinkers? Dogmatism is not demonstration, but when I was young nobody seemed to suspect it. It used to be said that "Darwin, Huxley, and Spencer were not really in a state of unknowingness concerning the great problem of the universe"--which meant that these eminent thinkers, upon whose lives no shadow of unveracity ever rested, described themselves as Limitationists when they were not so. They were not to be believed upon their word. The term was a mask. Such are the social penalties for taking sides with veracity. The public has begun to discover that veracity of speech is not a mask, but a duty. None can calculate the calamities which arise in society from the perpetual misdirections disseminated by those who make assertions resting merely upon their inherited belief or prepossessions, with no personal knowledge upon which they are founded. This is the sin of pretension, which recedes before the integrity of science and reason, just as wild beasts recede before the march of civilisation. Few would be prepared to believe that, in my polemical days, the desire to avoid committing the sin of pretension was supposed to indicate desperation of character, of which suicide would be the natural end. This was a favourite argument, for a heterodox principle was held to be for ever confuted, if he who held it hanged himself. The best proclaimed champion of orthodox tenets, whom I met on many platforms, went about declaring that I intended suicide, and it was generally believed that I had committed it. The certainty of it, sooner or later, was little doubted, whereas it was not at all in my way.
