Context: See they conducted experiments on convicts... I don't know on what grounds they reason a man in jail is a bigger liar than one out of jail... The chances are telling the truth is what got him there... It would be a big aid to humanity, but it will never be, for already the politicians are up in arms against it... It would wreck the very foundation on which our political government is run... If you ever injected truth into politics you'd have no politics … Even the ministers are denouncing it now … Humanity is not yet ready for either real truth or real harmony.

But philosophy has always been, and will always be, a fight with and a conquest of self-evident truths; philosophy is not looking for any "natural necessity", it sees in naturalness and in necessity alike an evil magic, which, if one cannot quite shake it off (for in this no mortal has ever yet succeeded), yet one must at least call by its right name; and even this is an important step! p. 342
