The main achievement of economics is that it has provided a theory of peaceful human cooperation. This is why the harbingers of violent conflict have branded it as a dismal science and why this age of wars, civil wars, and destruction has no use for it.

Two hundred years ago, before the advent of capitalism, a man's social status was fixed from the beginning to the end of his life; he inherited it from his ancestors and it never changed.

There is, in fact, only one solution: the state, the government, the laws must not in any way concern themselves with schooling or education. Public funds must not be used for such purposes. The rearing and instruction of youth must be left entirely to parents and to private associations and institutions

What can prevent the coming of totalitarian socialism is only a thorough change in ideologies. What we need is an open positive endorsement of that system to which we owe all the wealth that distinguished our age from the conditions of ages gone by.

Everyone carries a part of society on his shoulders; no one is relieved of his share of responsibility by others. And no one can find a safe way out for himself if society is sweeping toward destruction. Therefore, everyone, in his own interests, must thrust himself vigorously into the intellectual battle. None can stand aside with unconcern; the interest of everyone hangs on the result. Whether he chooses or not, every man is drawn into the great historical struggle, the decisive battle into which our epoch has plunged us.

Private property creates for the individual a sphere in which he is free of the state. It sets limits to the operation of the authoritarian will. It allows other forces to arise side by side with and in opposition to political power. It thus becomes the basis of all those activities that are free from violent interference on the part of the state. It is the soil in which the seeds of freedom are nurtured and in which the autonomy of the individual and ultimately all intellectual and material progress are rooted.

War is harmful, not only to the conquered but to the conqueror. Society has arisen out of the works of peace; the essence of society is peacemaking. Peace and not war is the father of all things. Only economic action has created the wealth around us; labor, not the profession of arms, brings happiness. Peace builds, war destroys.
