Sir John W. Salmond, Jurisprudence (1913)
“ No action will lie for their maintenance; yet they are, for all that, legal rights and legal duties, for they receive recognition from the law. The statute of limitations, for example, does not provide that after a certain time a debt shall become extinct, but merely that no action shall thereafter be brought for its recovery. Lapse of time, therefore, does not destroy the right, but merely reduces it from the rank of one which is perfect to that of one which is imperfect. It remains valid for all purposes save that of enforcement. ”
