Context: There are many hypotheses in science that are wrong. That's perfectly alright; it's the aperture to finding out what's right. Science is a self-correcting process. To be accepted, new ideas must survive the most rigorous standards of evidence and scrutiny.

To be accepted, new ideas must survive the most rigorous standards of evidence and scrutiny. The worst aspect of the Velikovsky affair is not that many of his ideas were wrong or silly or in gross contradiction to the facts; rather, the worst aspect is that some scientists attempted to suppress Velikovsky's ideas. The suppression of uncomfortable ideas may be common in religion or in politics, but it is not the path to knowledge and there is no place for it in the endeavor of science. We do not know beforehand where fundamental insights will arise from about our mysterious and lovely solar system, and the history of our study of the solar system shows clearly that accepted and conventional ideas are often wrong and that fundamental insights can arise from the most unexpected sources.

“While scientists themselves may be religious men of many different faiths, their methodology was designed to be the antithesis of faith because it requires that all assumptions be questioned, that all proposed explanations be based on demonstrable evidence, and that all hypotheses be must be testable and potentially falsifiable. Blaming magic is never acceptable because miracles aren’t explanations of any kind, and there has never been a single instance in history when assuming the supernatural has ever improved our understanding of anything. In fact such excuses have only ever impeded our attempts at discovery. This is one of many reasons why science depends on methodological naturalism; because unlike religion, science demands some way to determine who’s explanations are the more accurate, and which changes would actually be corrections. Science is a self-correcting process which changes constantly because its always improving. Only accurate information has practical application. So it doesn’t matter what you wanna believe. All that matters is why we should believe it too, and how accurate your perception can be shown to be. So you can’t just make up stuff in science (like you can in religion) because you have to substantiate everything, and be able to defend it even against peers who may not want to believe as you do. Be prepared to convince them anyway. Its possible to do that in science because science is based on reason. That means you must be ready to reject or correct whatever you hold true should you discover evidence against it.”

“It is a wicked thing to be neutral between right and wrong. Impartiality does not mean neutrality. Impartial justice consists not in being neutral between right and wrong, but in finding out the right and upholding it, wherever found, against the wrong.”

Part 3: "The Sense of Human Dignity", §6 (p. 63–64)
Science and Human Values (1956, 1965)
Context: Tolerance among scientists cannot be based on indifference, it must be based on respect. Respect as a personal value implies, in any society, the public acknowledgements of justice and of due honor. These are values which to the layman seem most remote from any abstract study. Justice, honor, the respect of man for man: What, he asks, have these human values to do with science? [... ]
Those who think that science is ethically neutral confuse the findings of science, which are, with the activity of science, which is not.
