Resumo
O presente artigo oferece uma reconstrução sistemática e um exame crítico da teoria fortemente semântica da informação (TSSI) de Luciano Floridi. Após situar o projeto floridiano no contexto mais amplo da filosofia da informação e identificar os problemas que o motivam (particularmente o paradoxo de Bar-Hillel–Carnap e o escândalo da dedução), o
artigo articula os compromissos centrais da TSSI: a definição geral de informação (GDI), a tese veritativa e a medida de informatividade i(P) = 1−[d(P)]². A dissolução floridiana de ambos os problemas clássicos é examinada e avaliada. O artigo avança então três objeções interconectadas que vão além das já estabelecidas na literatura: (i) a distinção entre 'ser
informativo' e 'ser informação' – que Floridi mobiliza para neutralizar o desafio das proposições falsas aparentemente informativas – revela-se instável e incapaz de sustentar o peso explicativo que a TSSI lhe impõe; (ii) confusões conceituais entre metadados, metainformação, informação dos dados e dados informacionais geram uma circularidade de
fundamentação na GDI que a metodologia dos níveis de abstração não dissolve; e (iii) descrições definidas introduzem indeterminação referencial que desestabiliza a própria medida de informatividade, dificuldade que não é periférica mas inerente a qualquer teoria da informação com pretensões de cobertura de representações em linguagem natural. O artigo posiciona também a TSSI em relação a alternativas baseadas em verossimilhança (Frické, D'Alfonso, Cevolani) e conclui esboçando, em termos deliberadamente prospectivos, uma direção de desenvolvimento fundada em adequação graduada e aptidão contextual.
