Love this tweet from John Cleese.
There is the obvious point about “belief.” Many people seem to think the scientific knowledge is a matter of belief and, in their eyes, something that can be subjectively chosen. That is ridiculous.
But also the wise stress on science as a method of investigation and not just a body of knowledge. Scientific knowledge is always imperfect and is dynamic changing with new data – but not in an arbitrary or chaotic way.
However imperfect our current knowledge the scientific method holds out possibilities for its improvement. And however may “mistakes” the cynic can find in our scientific knowledge they are always unable to suggest a way of correcting these mistakes except more science.
Science as a method of investigation remains by far the best way we have of understanding objective reality.
