The interpretation of Neurath's thought which has been advanced in the preceding pages is of course only one of the many which it is possible to envisage. The pluralistic lesson of the Foundations of the Social Sciences would be lost if we were not to recognise the possibility of a number of Neuraths, or of "pluri-Neurath", as he might put it himself. Nor should I, as author, attempt to conceal or minimise the force of the theoretical prejudices which must, inevitably, have contributed both to my selection of topics and to the presentation I have given them within a scheme of discourse for which I alone must bear the responsibility.
