I have never felt any desire to move a crowd, to exercise influence upon a mass of people—who lose their personality in being massed together—and on the other hand I have always felt a furious desire to perturb the heart of each individual man, to exercise an influence upon each one of my brothers in humanity. Whenever I have spoken in public I have almost always succeeded in employing a kind of lyrical oratory, and I have endeavoured to force upon myself the illusion that I was speaking to only one of my hearers, to any one, no matter which, to each one, not to all of them en masse.

We men are impenetrable. Spirits, like solid bodies, can only communicate with one another by the contact of surfaces, not by penetrating one another, still less by fusing together.

You have heard me say a thousand times that most spirits seem to me like crustaceans, with the bone outside and the flesh inside. And when in some book that I have forgotten I read what a painful and terrible thing it would be if the human spirit were to be incarnated in a crab and had to make use of the crab’s senses, organs and members, I said to myself: “This is what actually happens; we are all unfortunate crabs, shut up in hard shells.”

And the poet is he whose flesh emerges from the shell, whose soul oozes forth. And when, in our hours of anguish or joy, our soul oozes forth, we are all of us poets.

And that is why I believe that it is necessary to agitate the masses, to shake men and winnow them as in a sieve, to throw against one another, in order to see if in this way their shells will not break and their spirits flow forth, whether they will not mingle and unite with one another, and whether the real collective spirit, the soul of humanity, may not thus be welded together.

But the sad thing is, if we are to go by past experience, that all these mutual rubbings and clashings, far from breaking the shells, harden, thicken and enlarge them. They are like corns that grow larger and stronger with rubbing. Although perhaps it is that the clashes are not violent enough. And in any case it must be clashing, not rubbing. I do not like to rub against people but to clash against them; I do not like to approach people obliquely and glance off them at a tangent, but to meet them frontally, and if possible split them in two. It is the best service I can do them. And there is no better preparation for this task than solitude.

It is very sad that we have to communicate with one another by touching, at most by rubbing, through the medium of the hard shells that isolate us from one another. And I am convinced that this hard shell becomes weaker and more delicate, in solitude, until it changes into the most tenuous membrane which permits of the action of osmosis and exosmosis. And that is why I believe that it is solitude that makes men really sociable and human.

There are two kinds of union: one by removing differences, separating the elements that differentiate from those that unite, the other by fusion, bringing these differences into agreement. If we take away from the mind of each man that which is his own, that way of looking at things that is peculiar to him, everything that he takes care to hide for fear people should think him mad, we are left with that which he has in common with everyone else, and this common element gives us that wretched thing that is called common sense and which is nothing more than the abstract of the practical intelligence. But if we fuse into one the differing judgments of people, with all that they jealously preserve, and bring their caprices, their oddities, their singularities into agreement, we shall have human sense, which, in those who are rich in it, is not common but private sense.

The best that occurs to men is that which occurs to them when they are alone, that which they dare not confess, not only not to their neighbour but very often not even to themselves, that which they fly from, that which they imprison within themselves while it is in a state of pure thought and before it can flower into words. And the solitary is usually daring enough to express this, to allow it to flower, and so it comes about that he speaks that which others think in solitude by themselves and which nobody dares to publish. The solitary thinks everything aloud, and surprises others by saying that which they think beneath their breath, while they seek to deceive one another by pretending to make them believe that they are thinking something else, but without anybody believing them.

All this will help you to deduce for yourself in what way and to what extent solitude is the great school of sociability, and how right it is that we should sometimes withdraw ourselves from men in order that we may the better serve them.
