The Present Status of the "Lack of Mutuality" Rule, 36 Yale Law Journal 897 (1927)
The object of any science is to obtain general statements which will accurately describe those aspects of past events which have been noted and also serve as aids in forecasting future events. In the field of the so-called natural sciences, such general statements are called "laws of nature" or "natural laws"– the law of gravitation, the law of falling bodies, etc. , As a science develops, it turns out that as a larger and larger number of aspects of natural events are observed or as those previously noted are re-examined with more delicate or more powerful instruments, these general statements, so-called "natural laws," are found to be in need of revision or amendment. At the present time the scientific world, apparently partly because of the invention of better measuring instruments, but also for other reasons, is finding it necessary to revise not merely the statement of particular "laws" but the fundamental concepts in terms of which the "laws" are stated and with which it has worked so successfully for the past three centuries.
