Sir John W. Salmond, Jurisprudence (1913)
“ Practical legal exposition acknowledges no call to rise to first principles, or to proceed to ultimate analysis. From the point of view of law as an art, the importance of conceptions and principles varies inversely with their abstractness or generality. Practical jurisprudence proceeds from below upward, and ascends no further than the requirements of use and practice demand. Theoretical jurisprudence, on the contrary, attributes value to the abstract and the general, rather than to the concrete and the particular. ”
