Louis D. Brandeis

Our government is the potent, the omnipresent teacher. For good or ill, it teaches the whole people by its example.

America has believed that in differentiation, not in uniformity, lies the path of progress. It acted on this belief; it has advanced human happiness, and it has prospered.

In the frank expression of conflicting opinions lies the greatest promise of wisdom in governmental action.

Nearly all legislation involves a weighing of public needs as against private desires; and likewise a weighing of relative social values.
