"The division of opinion turns on the definition of property and the scope of contract. Physical things of themselves are powerless. Even liberty to choose between opportunities is passive and ineffective. But power to withhold opportunities is economic power, and associated power is government. When therefore liberty of contract is merged with property, it adds the liberty of persons to the exclusive holding of things. And this liberty operates in the several directions of liberty to combine their property into an industrial government and to act as a unit, not only in proportioning their resources economically but also in choosing opportunities, in commanding obedience, in persuading or coercing, and in planning for the expectations of an indefinite future."

“Liberty is absence of restraint. Freedom is participation in government.”

“It is an easy and patriotic matter for the lawyer, minister, professor, employer, or investor, placed above the arena of competition, to proclaim the equal right of all races to American opportunities; to avow his own willingness to give way should even a better Chinaman, Hindu, or Turk come in to take his place; and to rebuke the racial hatred of those who resist this displacement. His patriotism and world-wide brotherhood cost him and his family nothing, and indeed they add to his profits and leisure.”

“Legally, the term liberty means absence of duty, or rather the limit of duty.”

“While mere process of thinking is the process of habits, ideals, definitions, investigations, classifications, valuations and behavior, due process of thinking, which is due process of law, is the process of correct habits, right ideals, true definitions, sincere investigation, reasonable classification, reasonable value, and justice; whereas its opposite, undue process, is perverse habit, wrong ideals, double meanings, partial investigation, class legislation, confiscation and injustice.”

“The ‘liberty’ of one is his permission to act as he pleases, supported against interference by the power of the concern or government”

“Economic theory deals with two concepts, Value and Economy. Abstract reasoning regarding these concepts rests ultimately on mathematical concepts of quantity, time and energy. The three are inseparable, for quantity and time are dimensions of energy. The quantity relationships of energy, usually termed "statics," turn on the problem of the relation of the parts to the whole, while the time relationships, usually termed "dynamics," are the relations of a process that connects past, present and future.”
