Even if society were unable to obtain these concessions and sacrifices from us except by a material constraint, it might awaken in us only the idea of a physical force to which we must give way of necessity, instead of that of a moral power such as religions adore. But as a matter of fact, the empire which it holds over consciences is due much less to the physical supremacy of which it has the privilege than to the moral authority with which it is invested. If we yield to its orders, it is not merely because it is strong enough to triumph over our resistance; it is primarily because it is the object of a venerable respect.
We say that an object, whether individual or collective, inspires respect when the representation expressing it in the mind is gifted with such a force that it automatically causes or inhibits actions, _without regard for any consideration relative to their useful or injurious effects_. When we obey somebody because of the moral authority which we recognize in him, we follow out his opinions, not because they seem wise, but because a certain sort of physical energy is imminent in the idea that we form of this person, which conquers our will and inclines it in the indicated direction. Respect is the emotion which we experience when we feel this interior and wholly spiritual pressure operating upon us. Then we are not determined by the advantages or inconveniences of the attitude which is prescribed or recommended to us; it is by the way in which we represent to ourselves the person recommending or prescribing it. This is why commands generally take a short, peremptory form leaving no place for hesitation; it is because, in so far as it is a command and goes by its own force, it excludes all idea of deliberation or calculation; it gets its efficacy from the intensity of the mental state in which it is placed. It is this intensity which creates what is called a moral ascendancy.
Now the ways of action to which society is strongly enough attached to impose them upon its members, are, by that very fact, marked with a distinctive sign provocative of respect. Since they are elaborated in common, the vigour with which they have been thought of by each particular mind is retained in all the other minds, and reciprocally. The representations which express them within each of us have an intensity which no purely private states of consciousness could ever attain; for they have the strength of the innumerable individual representations which have served to form each of them. It is society who speaks through the mouths of those who affirm them in our presence; it is society whom we hear in hearing them; and the voice of all has an accent which that of one alone could never have.[678] The very violence with which society reacts, by way of blame or material suppression, against every attempted dissidence, contributes to strengthening its empire by manifesting the common conviction through this burst of ardour.[679] In a word, when something is the object of such a state of opinion, the representation which each individual has of it gains a power of action from its origins and the conditions in which it was born, which even those feel who do not submit themselves to it. It tends to repel the representations which contradict it, and it keeps them at a distance; on the other hand, it commands those acts which will realize it, and it does so, not by a material coercion or by the perspective of something of this sort, but by the simple radiation of the mental energy which it contains. It has an efficacy coming solely from its psychical properties, and it is by just this sign that moral authority is recognized. So opinion, primarily a social thing, is a source of authority, and it might even be asked whether all authority is not the daughter of opinion.[680] It may be objected that science is often the antagonist of opinion, whose errors it combats and rectifies. But it cannot succeed in this task if it does not have sufficient authority, and it can obtain this authority only from opinion itself. If a people did not have faith in science, all the scientific demonstrations in the world would be without any influence whatsoever over their minds. Even to-day, if science happened to resist a very strong current of public opinion, it would risk losing its credit there.[681]
