About This Quote
There are no forbidden questions in science, no matters too sensitive or delicate to be probed, no sacred truths. Scientists, like any other human beings, make mistakes. They do not believe everything they are told by their bosses or the media, and they do not engage in polluting activities with no consequences. They make mistakes, but they also ask questions, and they try to answer them.
