Sir John W. Salmond, Jurisprudence (1913)
“ So great is the superiority of legislation over all other methods of legal evolution, that the tendency of advancing civilisation is to acknowledge its exclusive claim, and to discard the other instruments as relics of the infancy of law. The expressed will of the state tends to obtain recognition not only as the sole formal source of law, but as its exclusive material source also. Statute law has already become the type or standard, from which the other forms are more or less abnormal variations. ”
