But the scientific importance of a change in knowledge of fact consists precisely in j its having consequences for a system of theory. – Talcott Parsons
It is that of increasing knowledge of empirical fact, intimately combined with changing interpretations of this body of fact – hence changing general statements about it – and, not least, a changing a structure of the theoretical system. – Talcott Parsons
The conception that, instead of this, contemporary society is at or near a turning point is very prominent in the views of a school of social scientists who, though they are still comparatively few, are getting more and more of a hearing. – Talcott Parsons
From all this it follows what the general character of the problem of the development of a body of scientific knowledge is, in so far as it depends on elements internal to science itself. – Talcott Parsons
