J. Robert Oppenheimer // "There must be no barriers to freedom of inquiry...The scientist is free, and must be free to ask any question, to doubt any assertion, to seek for any evidence, to correct any errors. Our political life is also predicated on openness...as long as men are free to ask what they must, free to say what they think, free to think what they will, freedom can never be lost, and science can never regress."
