Why does a flock of birds rise suddenly from the treetops, all at once, in one spring, and swirl round in one cloud towards the water? There was no visible sign or communication given. It was a telepathic communication. They sat and waited, and waited, and let the individual mind merge into a kind of collective trance. Then click!—the unison was complete, the knowledge or suggestion was one suggestion all through, the action was one action.

This so-called telepathy is the clue to all herd instinct. It is not instinct. It is a vertebral-telegraphy, like radio-telegraphy. It is a complex interplay of vibrations from the big nerve-centres of the vertebral system in all the individuals of the flock, till, click!—there is a unanimity. They have one mind. And this one-mindedness of the many-in-one will last while ever the peculiar pitch of vertebral nerve-vibrations continues unbroken through them all. As the vibration slacks off, the flock falls apart.

This vertebral telepathy is the true means of communication between animals. It is perhaps most highly developed where the brain, the mental consciousness, is smallest. Indeed the two forms of consciousness, mental and vertebral, are mutually exclusive. The highest form of vertebral telepathy seems to exist in the great sperm whales. Communication between these herds of roving monsters is of marvellous rapidity and perfection. They are lounging, feeding lazily, individually, in mid-ocean, with no cohesion. Suddenly, a quick thought-wave from the leader-bull, and as quick as answering thoughts the cows and young bulls are ranged, the herd is taking its direction with a precision little short of miraculous. Perhaps water acts as a most perfect transmitter of vertebral telepathy.

This is the famous wisdom of the serpent, this vertebral consciousness and telepathy. This is what makes the magic of a leader like Napoleon—his powers of sending out intense vibrations, messages to his men, without the exact intermediation of mental correspondence. It is not brain-power. In fact, it is, in some ways, the very reverse of brain-power: it might be called the acme of stupidity. It is the stupendous wits of brainless intelligence. A marvellous reversion to the pre-mental form of consciousness.

This pre-mental form of consciousness seems most perfect in the great whales: more even in them than in the flocks of migrating birds. After the whales, the herds of wolves and deer and buffaloes. But it is most absolute in the cold fishes and serpents, reptiles. The fishes have no other correspondence save this cold, vertebral vibration. And this is, as it were, blind. The fish is absolutely stone-wall limited in its consciousness, to itself. It knows none other. Stony, abstract, cold, alone, the fish has still the power of radio-communication. It is a form of telepathy, like a radium-effluence, vibrating fear principally. Fear is the first of the actuating gods.

Then come the reptiles. They have sex, and dimly, darkly discern the bulk of the answerer. They are drawn to contact. It is the new motive. The fishes are never drawn to contact. Only food and fear. So in the reptiles the second telepathic vibration, the sympathetic, is set up. The primary consciousness is cold, the wisdom is isolated, cold, moon-like, knowing none other: the self alone in knowledge, utterly subtle. But then sex comes upon them, and the isolation is broken. Another flow sets up. They must seek the answerer. It is love.

So, telepathy, communication in the vertebrates. Ants and bees too have a one-conscious vibration. Even they have perfect ganglia-communication. But it is enough to consider the vertebrates.

In the sperm whale, intense is the passion of amorous love, intense is the cold exultance in power, isolate kingship. With the most intense enveloping vibration of possessive and protective love, the great bull encloses his herd into a oneness. And with the intensest vibration of power he keeps it subdued in awe in fear. These are the two great telepathic vibrations which rule all the vertebrates, man as well as beast. Man, whether in a savage tribe or in a complex modern society, is held in unison by these two great vibrations emitted unconsciously from the leader, the leaders, the governing classes, the authorities. First, the great influence of shadow of power, causing trust, fear and obedience: second, the great influence of protective love, causing productivity and the sense of safety. Those two powerful influences are emitted by men like Gladstone or Abraham Lincoln, against their knowledge, but none the less emitted. Only Gladstone and Lincoln justify themselves in speech. And both insist on the single influence of love, and denounce the influence of fear.

A mob occurs when men turn upon all leadership. For true, living activity the mental and the vertebral consciousness should be in harmony. In Cæsar and Napoleon the vertebral influence of power prevailed—and there was a break of balance, and a fall. In Lincoln and President Wilson the vertebral influence of love got out of balance, and there was a fall. There was no balance between the two modes of influence: the mind ran on, as it were, without a brake, towards absurdity. So it ran to absurdity in Napoleon.

Break the balance of the two great controlling influences, and you get, not a simple preponderance of the one influence, but a third state, the mob-state. This is the state when the society tribe or herd degenerates into a mob. In man, the mind runs on with a sort of terrible automatism, which has no true connection with the vertebral consciousness. The vertebral inter-communication gradually gathers force, apart from all mental expression. Its vibration steadily increases till there comes a sudden click! And then you have the strange phenomenon of revolution, like the Russian and the French revolutions. It is a great disruptive outburst. It is a great eruption against the classes in authority. And it is, finally, a passionate, mindless vengeance taken by the collective, vertebral psyche upon the authority of orthodox mind. In the Russian revolution it was the educated classes that were the enemy really: the deepest inspiration the hatred of the conscious classes. But revolution is not a mob-movement. Revolution has direction, and leadership, however temporary. There is point to its destructive frenzy.
