The new foes must be met, as the old ones were met--by institutions and guarantees. The problem of civil liberty is constantly renewed. Solved once, it re-appears in a new form. The old constitutional guarantees were all aimed against king and nobles. New ones must be invented to hold the power of wealth to that responsibility without which no power whatever is consistent with liberty. The judiciary has given the most satisfactory evidence that it is competent to the new duty which devolves upon it. The courts have proved, in every case in which they have been called upon, that there are remedies, that they are adequate, and that they can be brought to bear upon the cases. The chief need seems to be more power of voluntary combination and co-operation among those who are aggrieved. Such co-operation is a constant necessity under free self-government; and when, in any community, men lose the power of voluntary co-operation in furtherance or defense of their own interests, they deserve to suffer, with no other remedy than newspaper denunciations and platform declamations. Of course, in such a state of things, political mountebanks come forward and propose fierce measures which can be paraded for political effect. Such measures would be hostile to all our institutions, would destroy capital, overthrow credit, and impair the most essential interests of society. On the side of political machinery there is no ground for hope, but only for fear. On the side of constitutional guarantees and the independent action of self-governing freemen there is every ground for hope.
