ABSTRACT
Leaving aside the forms of scientific enquiry that may be purely documentary or descriptive in purpose—it seems that no attempt to solve a scientific problem can even be begun without the subsidy of some hypothesis, however dimly formulated or however vague. The experienced clinician is very well aware of the intuitive nature of the act of mind by which he hits on an hypothesis, but he sometimes fails to realize that this is the commonplace of scientific discovery: hence the fuss. The existence of an experimental method in this generalized sense is what distinguishes the scientific method from that of any other sort of scholarly enquiry, and it is to this method that science owes its power. 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 written down.
