THE UNIQUENESS OF THE INDIVIDUAL 



layman seem to be so characteristically scientific. These things 

 belong not to scientific method in its more formal sense but to 

 the theory of experimental design and scientific analysis, and 

 the exacting requirements of scientific reportage. Obviously an 

 experiment must be done in such a way as to give an un- 

 ambiguous answer, and in the examination of events one must 

 aspire to put on record that which is indeed the case. All this 

 belongs to the technology of scientific method. 



The growth of science is organic and not accretionary. The 

 structure of knowledge built up by the prosecution of the 

 scientific method as I have outlined it is a tapering hierarchy 

 of hypotheses, the more general counting the less general 

 among their consequences, the least general — the ordinary 

 colligative inductions — finally touching down in a multitude of 

 particular statements about fact. The structure of scientific 

 knowledge is therefore in the outcome logico-deductive, and 

 this is the form in which what Berkeley called the Grammar of 

 Nature is finally wTitten down. It is already a record of some 

 grandeur, though the greater part has yet to be compiled.
