Among those who are satisfactory in this respect it is desirable to have represented as great a diversity of intellectual tradition, social milieu and personal character as possible. ↗
But the fact a person denies that he is theorising is no reason for taking him at his word and failing to investigate what implicit theory is involved in his statements. ↗
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. ↗
Now obviously the propositions of the system have reference to matters of empirical fact; if they did not, they could have no claim to be called scientific. ↗
Special emphasis should be laid on this intimate interrelation of general statements about empirical fact with the logical elements and structure of theoretical systems. ↗
Thus, in general, in the first instance, the direction of interest in empirical fact will be canalised by the logical structure of the theoretical system. ↗
