My guess is your use of "plausible" vs "possible" probably refers in the idea of evolution to Ernst Mayr's willingness to go forward in the face of criticism of the lack of specified 'parameters' of evolution.
The current movement in philosophy of biology however would not appreciate being told it does not make evolution by force without plausibility.
It is possible you are correct, but I tend to think that scientists actually do have all the concepts they need to do their work. The problem is that they may not be supported. If there are facutally millions of years then by the time the sun blows off earth we should be in a position to know this. The problem is that joking jabs aside, it is not nice to be categorically excluded because one may want to reserve the philosophy of time (say post-Bergson)to a dinner conversation only and not be subject to TV commercials that call for speeding up (the time) of "evolution".
Who controls broadcasts should also not be the same people only who recieve behavoir needed to confirm or reject a result of education.
The debate continues...
Hope I never create anything as monolithic as I have in the past.
