It is important to stress that within this general consensus, there was considerable room for diversity among philosophers. Thus one large group of philosophers within this consensus could be labeled "positivists," or more specifically "logical positivists" or "logical empiricists," and indeed they tended to dominate.  For many purposes what I am calling the "empiricist consensus" might be called the "positivist model" of scientific knowledge. However, the posiitivists had other philosophical agendas which I would not want to consider part of the "consensus"; moreover, other philosophers, for example, Bertrand Russell or Karl Popper, could be placed within this consensus but disagreed sharply with the positivists. [see Hacking, R&I, Introduction,  for a comparison of what Popper and Carnap (the positivist) held in common.]
