"It is important to distinguish between the scientific concept of law as a generalization, and the social concept of law which is prescriptive and normative. A desire for tolerance in respecting the laws of different social systems must not lead us into the mistake of attributing volition to the entities of science or relativism to scientific laws."

“A good rule of thumb for diagnosing an activity as pseudoscientific is the existence of ad hoc explanations: “my telepathic powers aren’t working today because of a force field emanating from the hostile talk-show host.” There are no “bad-gravity days” and there are no days when your TV set stops working because electromagnetic waves feel hostility.”

“Enormous resources are invested in pseudoscience that could be better invested in improving the health and education of the public.”

“The difference between these beliefs and the beliefs of religions is that scientific beliefs are methodological, not propositional...It is the absence of propositional beliefs that distinguishes science from a belief system. There is no proposition of the content of science that is accepted upon belief alone.”

“Just because people doing science are embedded in a particular social and cultural milieu, it doesn’t follow that science is not universal.”

“The charm of our studies, the enchantment of science, is that, everywhere and always, we can give the justification of our principles and the proof of our discoveries.”

“The statement “I don’t see how X could have evolved” simply means that you cannot see how X evolved, not that X could not have evolved.”
