Does Anything does not go mean that everything will not always go ahead as expected?
And, is it an independent sentence and phrase or is it referring to "critical" in the next sentence like X (Anything does not go) and B (the hopefully impartial views of other experts) are critical?
And all but the most corrupt share the same desire to find some kind of truth about the structures, behaviours and contexts of the phenomena they study within their specialisms, even if they have to stay prepared for revolutionary changes of perspective. Anything does not ‘go’ and the hopefully impartial views of other experts are critical. And the quest for knowledge, real knowledge, drives everyone before it.
