"When information needs to be communicated, Edward Tufte demands both truth and beauty... But what inspires Tufte is more than aesthetics. Galileo\'s observations, recorded in nearly 12,000 pages, marked an intellectual revolution. No longer was knowledge the dictate of church authorities, kings or the acolytes of Aristotle. Theories could be testedÃ¢â¬âdoctrine could be upendedÃ¢â¬âby what the eye can see. As Tufte sees it, what makes evidence beautiful isn\'t artistry. 'It\'s all about discovering and telling the truth,' he says."
