To Dr. Joseph Priestley

Washington, March 21, 1801

Dear Sir, – I learnt some time ago that you were in Philadelphia, but that it was only for a fortnight; & supposed you were gone. It was not till yesterday I received information that you were still there, had been very ill, but were on the recovery. I sincerely rejoice that you are so. Yours is one of the few lives precious to mankind, & for the continuance of which every thinking man is solicitous. Bigots may be an exception. What an effort, my dear Sir, of bigotry in Politics & Religion have we gone through! The barbarians really flattered themselves they should be able to bring back the times of Vandalism, when ignorance put everything into the hands of power & priestcraft. All advances in science were proscribed as innovations. They pretended to praise and encourage education, but it was to be the education of our ancestors. We were to look backwards, not forwards, for improvement; the President himself declaring, in one of his answers to addresses, that we were never to expect to go beyond them in real science. This was the real ground of all the attacks on you. Those who live by mystery & charlatanerie, fearing you would render them useless by simplifying the Christian philosophy, – the most sublime & benevolent, but most perverted system that ever shone on man, – endeavored to crush your well-earnt & well-deserved fame.
