The term schizoid refers to an individual the totality of whose experience is split in two main ways: in the first place, there is a rent in his relation with his world and, in the second, there is a disruption of his relation with himself. Such a person is not able to experience himself 'together with' others or 'at home in' the world, but, on the contrary, he experiences himself in despairing aloneness and isolation; moreover, he does not experience himself as a complete person but rather as 'split' in various ways, perhaps as a mind more or less tenuously linked to a body, as two or more selves, and so on.
