abnormalities were such things as no arms‚ no legs or very disfigured limbs. Around 15‚000 foetuses were damaged by thalidomide‚ of whom about 12‚000 in 46 countries were born with birth defects‚ with only 8‚000 of them surviving past the first year of life. Most of these survivors are still alive‚ nearly all with disabilities caused by the drug. In 2003‚ a World Health 10 Organisation newsletter quoted evidence that the disabilities and deformities in many thalidomide survivors may be passed on to

theories on the workings of the ‘self’—or‚ spiritually speaking‚ the soul. An influential example of such would be Erving Goffman’s theory of self-presentation—a deeply faceted analysis of the human psyche.
