Strictly speaking, the mass, as a psychological fact, can be defined without waiting for individuals to appear in mass formation. In the presence of one individual we can decide whether he is "mass" or not. The mass is all that which sets no value on itself — good or ill — based on specific grounds, but which feels itself "just like everybody," and nevertheless is not concerned about it; is, in fact, quite happy to feel itself as one with everybody else.
