Unless a man is honest, we have no right to keep him in public life; it matters not how brilliant his capacity.
But lest I should mislead any when I have my own head and obey my whims, let me remind the reader that I am only an experimenter.Do not set the least value on what I do, or the least discredit on what I do not, as if I pretended to settle any thing as true or false. I unsettle all things. No facts are to me sacred; none are profane; I simply experiment, an endless seeker with no Past at my back.
So long as the priest, that professional negator, slanderer and poisoner of life, is regarded as a superior type of human being, there cannot be any answer to the question: What is Truth?
'In his celebrated book, 'On Liberty', the English philosopher John Stuart Mill argued that silencing an opinion is "a peculiar evil." If the opinion is right, we are robbed of the "opportunity of exchanging error for truth"; and if it's wrong, we are deprived of a deeper understanding of the truth in its "collision with error." If we know only our own side of the argument, we hardly know even that: it becomes stale, soon learned by rote, untested, a pallid and lifeless truth.'
