This fundamental characteristic of the social instinct renders intolerable and even hateful the friendship of frivolous persons, liable to be infatuated with every new face, accommodating to all whether good or bad, and ready to sacrifice, for a passing liaison, the oldest and most honorable affections.

The fault of such beings is not in the heart--it is in the judgment.

Sociability, in this degree, is a sort of magnetism awakened in us by the contemplation of a being similar to ourselves, but which never goes beyond the person who feels it; it may be reciprocated, but not communicated.

Love, benevolence, pity, sympathy, call it what you will, there is nothing in it which deserves esteem,--nothing which lifts man above the beast.
The second degree of sociability is justice, which may be defined as the RECOGNITION OF THE EQUALITY BETWEEN ANOTHER'S PERSONALITY AND OUR OWN.
The sentiment of justice we share with the animals; we alone can form an exact idea of it; but our idea, as has been said already, does not change its nature.

We shall soon see how man rises to a third degree of sociability which the animals are incapable of reaching.
