Campbell wrote the book The Hero With a Thousand Faces, which was one of the inspirations for Star Wars. He was interviewed by Bill Moyers in a six hour series in the 1980s on PBS. That series was called The Power of Myth.
Here is one passage:
““This is the threat to our lives that we all face today. Is the system going to flatten you out and deny you your humanity, or are you going to be able to make use of the system to the attainment of human purposes? How do you relate to the system so that you are not compulsively serving it? It doesn’t help to try to change it to accord with your system of thought. The momentum of history behind it is too great for anything really significant to evolve from that kind of action. The thing to do is learn to live in your period of history as a human being. That’s something else, and it can be done.””
Here is another:
“The world is a wasteland. People have the notion of saving the world by shifting it around and changing the rules and so forth. No, any world is a living world if it’s alive, and the thing is to bring it to life. And the way to bring it to life is to find in your own case where your life is, and be alive yourself, it seems to me.”
Adam Smith said something that seemed similar in his book The Theory of Moral Sentiments:
“The natural course of things cannot be entirely controlled by the impotent endeavours of man: the current is too rapid and too strong for him to stop it; and though the rules which direct it appear to have been established for the wisest and best purposes, they sometimes produce effects which shock all his natural sentiments.”
Smith also seems to be hinting at the law of unintended consequences. Here is a longer excerpt to see the context:
“But though the general rules by which prosperity and adversity are commonly distributed, when considered in this cool and philosophical light, appear to be perfectly suited to the situation of mankind in this life, yet they are by no means suited to some of our natural sentiments. Our natural love and admiration for some virtues is such, that we should wish to bestow on them all sorts of honours and rewards, even those which we must acknowledge to be the proper recompenses of other qualities, with which those virtues are not always accompanied. Our detestation, on the contrary, for some vices is such, that we should desire to heap upon them every sort of disgrace and disaster, those not excepted which are the natural consequences of very different qualities. Magnanimity, generosity, and justice, command so high a degree of admiration, that we desire to see them crowned with wealth, and power, and honours of every kind, the natural consequences of prudence, industry, and application; qualities with which those virtues are not inseparably connected. Fraud, falsehood, brutality, and violence, on the other hand, excite in every human breast such scorn and abhorrence, that our indignation rouses to see them possess those advantages which they may in some sense be said to have merited, by the diligence and industry with which they are sometimes attended. The industrious knave cultivates the soil; the indolent good man leaves it uncultivated. Who ought to reap the harvest? who starve, and who live in plenty? The natural course of things decides it in favour of the knave: the natural sentiments of mankind in favour of the man of virtue. Man judges, that the good qualities of the one are greatly over-recompensed by those advantages which they tend to procure him, and that the omissions of the other are by far too severely punished by the distress which they naturally bring upon him; and human laws, the consequences of human sentiments, forfeit the life and the estate of the industrious and cautious traitor, and reward, by extraordinary recompenses, the fidelity and public spirit of the improvident and careless good citizen. Thus man is by Nature directed to correct, in some measure, that distribution of things which she herself would otherwise have made. The rules which for this purpose she prompts him to follow, are different from those which she herself observes. She bestows upon every virtue, and upon every vice, that precise reward or punishment which is best fitted to encourage the one, or to restrain the other. She is directed by this sole consideration, and pays little regard to the different degrees of merit and demerit, which they may seem to possess in the sentiments and passions of man. Man, on the contrary, pays regard to this only, and would endeavour to render the state of every virtue precisely proportioned to that degree of love and esteem, and of every vice to that degree of contempt and abhorrence, which he himself conceives for it. The rules which she follows are fit for her, those which he follows for him: but both are calculated to promote the same great end, the order of the world, and the perfection and happiness of human nature.
But though man is thus employed to alter that distribution of things which natural events would make, if left to themselves; though, like the gods of the poets, he is perpetually interposing, by extraordinary means, in favour of virtue, and in opposition to vice, and, like them, endeavours to turn away the arrow that is aimed at the head of the righteous, but to accelerate the sword of destruction that is lifted up against the wicked; yet he is by no means able to render the fortune of either quite suitable to his own sentiments and wishes. The natural course of things cannot be entirely controlled by the impotent endeavours of man: the current is too rapid and too strong for him to stop it; and though the rules which direct it appear to have been established for the wisest and best purposes, they sometimes produce effects which shock all his natural sentiments. That a great combination of men should prevail over a small one; that those who engage in an enterprise with forethought and all necessary preparation, should prevail over such as oppose them without any; and that every end should be acquired by those means only which Nature has established for acquiring it, seems to be a rule not only necessary and unavoidable in itself, but even useful and proper for rousing the industry and attention of mankind. Yet, when, in consequence of this rule, violence and artifice prevail over sincerity and justice, what indignation does it not excite in the breast of every human spectator? What sorrow and compassion for the sufferings of the innocent, and what furious resentment against the success of the oppressor? We are equally grieved and enraged at the wrong that is done, but often find it altogether out of our power to redress it. When we thus despair of finding any force upon earth which can check the triumph of injustice, we naturally appeal to heaven, and hope, that the great Author of our nature will himself execute hereafter, what all the principles which he has given us for the direction of our conduct, prompt us to attempt even here; that he will complete the plan which he himself has thus taught us to begin; and will, in a life to come, render to every one according to the works which he has performed in this world. And thus we are led to the belief of a future state, not only by the weaknesses, by the hopes and fears of human nature, but by the noblest and best principles which belong to it, by the love of virtue, and by the abhorrence of vice and injustice.”
