There must be no barriers to freedom of inquiry. There is no place for dogma in science. 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. We know that the only way to avoid error is to detect it and that the only way to detect it is to be free to inquire. And we know that 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.
When it comes to such open-heart reflection, I'm a firm believer in the observer effect, which states that anything you try to observe is automatically changed by the mere fact that you're looking at it. The way I see it, if you try to study your emotions on a microscopic level, the best you can do is understand how it feels to hold the magnifying glass.
