The Social Construction of Reality (Peter Berger, Thomas Luckmann, 1966)
“To be given an identity involves being assigned a specific place in the world. As this identity is subjectively appropriated by the child ('I am John Smith'), so is the world to which this identity points. (...)
He is imprisoned in the objective reality of his society, although that reality is subjectively present to him in an alien and truncated manner.
Such an individual will be unsuccessfully socialized, that is, there will be a high degree of asymmetry between the socially defined reality in which he is de facto caught, as in an alien world, and his own subjective reality, which reflects that world only very poorly. (...)
As long as such individuals, even if they number more than a handful, do not form a counter-community of their own, both their objective and subjective identities will be predefined in accordance with the community's institutional programme for them. They will be lepers, and nothing else. (...)
Incipient counter-definitions of reality and identity are present as soon as any such individuals congregate in socially durable groups.
This triggers a process of change that will introduce a more complex distribution of knowledge. A counter-reality may now begin to be objectivated in the marginal group of the unsuccessfully socialized. (...)
The individuals prevented from fully internalizing the reality of the community may now be socialized into the counter-reality of the lepers' colony; that is, unsuccessful socialization into one social world may be accompanied by successful socialization into another. (...)
Maximally, it will no longer be an easy matter to recognize anybody's identity - for if lepers can refuse to be what they are supposed to be, so can others; perhaps, so can oneself.
If this process appears fanciful at first, it is beautifully illustrated by Gandhi's designation of harijans, that is, 'children of God', for the outcastes of Hinduism.”
