(c) Freedom. By far the most important of all the conditions, under which the production of material commodities goes broadly forward, is liberty of action on the part of the individual; because, wherever such liberty is conceded, association and invention and all other needful conditions follow right along by laws of natural sequence. By liberty of individual action is meant the practical right of every man to employ his own efforts for the satisfaction of his own wants in his own way, whether directly or through exchange. Each man's right of individual freedom is limited of course by every other man's right to equal freedom, which the first man is not at liberty to infringe; and also, in certain few and limited respects, by what is sometimes called the "general good," the judge of the application of which must be the government under which the man lives. With these limitations, which are few in number and never serious in degree when rightly applied, and which limit in common all other rights whatsoever, the right of every man to buy and sell and get gain is just as fully a right as the right of breathing. It stands on the same impregnable ground. It is a natural and self-evident and inalienable right, with which each man has been endowed by his Creator, to put forth efforts for his own well-being and for those dependent upon him, either directly or by means of efforts exchanged with other men equally free; and he is a slave in spirit and position, who tamely submits to have his own rights of buying and selling curtailed, or to stand by and see the rights of his fellow-citizens similarly curtailed, unless such act of interference and curtailment on the part of his Government be justified by a solid proof that some other public or private rights, which are at least as well based as his own, would be endangered by the exercise of his own.
