I. F. Stone said this quote

I'm working on this book on the trial of Socrates. It started out with the idea of the problem of freedom of thought...and expression...I started by spending a year on the English Seventeenth Century Revolutions, and I had a fascinating time. And then I felt I couldn't understand the English Seventeenth Century Revolutions without understanding the Reformation. When I got to the Reformation, I felt that I had to understand the premonitory movements that began in the Middle Ages. When I got there, I felt I had to understand the classical period. (quoted in Andrew Patner, I. F. Stone: A Portrait, p. 21)

~ I. F. Stone

If you live long enough the venerability factor creeps in you get accused of things you never did and praised for virtues you never had.

~ I. F. Stone

Every emancipation has in it the seeds of a new slavery, and every truth easily becomes a lie.
