Riscos não estão relacionados ao que os cientistas sabem, mas ao que eles não sabem.
Riscos estão associados a incertezas.
Caruso, D. Intervention. San Francisco, Hybrid Vigor Press, 2006, 252p.
RISCO.....
Pois é no contexto da incerteza que viceja a esperança, o juízo e a valoração da subjetividade, capaz de concretizar o inusitado.
