"The third element alone remains — the institution itself, acting in such a way as to make social acts a state of habit and instinct. This element — history proves it — has never missed its aim, never has it acted as a double-bladed sword; and its influence has only been weakened when custom strove to become immovable, crystallized, to become in its turn a religion not to be questioned when it endeavored to absorb the individual, taking all freedom of action from him and compelling him to revolt against that which had become, through its crystallization, an enemy to progress."
