I am ready to concede that the rule of adherence to precedent, though it ought not to be abandoned, ought to be in some degree relaxed. I think that … - Benjamin N. Cardozo

The law has outgrown its primitive stage of formalism when the precise word was the sovereign talisman, and every slip was fatal. It takes a broader view to-day. A promise may be lacking, and yet the whole writing may be "instinct with an obligation," imperfectly expressed. If that is so, there is a contract.

The reconciliation of the irreconcilable, the merger of antitheses, the synthesis of opposites, these are the great problems of the law... We have the claims of stability to be harmonized with those of progress. We are to reconcile liberty with equality, and both of them with order. The property rights of the individual we are to respect, yet we are not to press them to the point at which they threaten the welfare or the security of the many. We must preserve to justice its universal quality, and yet leave to it the capacity to be individual and particular.

Price security, we are told, is only a special form of sanitary security; the economic motive is secondary and subordinate; the state intervenes to make its inhabitants healthy, and not to make them rich. On that assumption we are asked to say that intervention will be upheld as a valid exercise by the state of its internal police power, though there is an incidental obstruction to commerce between one state and another. This would be to eat up the rule under the guise of an exception. Economic welfare is always related to health, for there can be no health if men are starving. Let such an exception be admitted, and all that a state will have to do in times of stress and strain is to say that its farmers and merchants and workmen must be protected against competition from without, lest they go upon the poor relief lists or perish altogether. To give entrance to that excuse would be to invite a speedy end of our national solidarity. The Constitution was framed under the dominion of a political philosophy less parochial in range. It was framed upon the theory that the peoples of the several states must sink or swim together, and that in the long run prosperity and salvation are in union and not division.
