Indisputable

"Liberty cannot be preserved without a general knowledge among the people, who have a right, from the frame of their nature, to knowledge, as their great Creator, who does nothing in vain, has given them understandings, and a desire to know; but besides this, they have a right, an indisputable, unalienable, indefeasible, divine right to that most dreaded and envied kind of knowledge; I mean, of the characters and conduct of their rulers."
--John Adams
(1735-1826) Founding Father, 2nd US President
