any definition or classification is others' prerogative. I can say whatever I want about myself - "I'm very smart"; "I play guitar very well"... - that doesn't count. Classifying is a third party prerogative and the only valid one. GPC Classificar é atribuir 'propriedades'. Associar um objeto a um ponto (ou zona) no "espaço classificativo" que arbitrariamente se define.
