Two freedoms live in any human: natural and human.
There is no human in nature, ape exists.
Human is the ape with something unnatural in it. Speech is this "unnatural something." Human is an ape with a gift of speech. Ape doesn't call itself ape, nature doesn't define herself as nature. Those who give names are people.
Anything can be a signal. Some can send signals and understand them.
Humans communicate.
Natural freedom is freedom of apes, lions, plankton. Animal freedom.
Animal freedom is freedom to be a member of a flock and receive benefits of being included in flock. Flock is always organized hierarchically. Animal can be alpha male or beta-, delta-, zeta-male, but it is part of hierarchy. An animal can live outsude a flock, but it is a flock still, flock which consists of one only participant.
Animal freedom is freedom of individual, whose life is determined by collective.
Human freedom is freedom of personality. Personality is not defined by collective, flock, milieu or anything else.
