In Prometheus Bound, Aeschylus takes the side of the hero who defied Zeus and gave fire to human beings. It is undeniable that scientific progress is one of the greatest achievements of man. Scientists, the creators of new knowledge, bear his name: “he who thinks first”. New knowledge is transformed by companies into innovations introduced in production. These autonomous decisions have a very wide impact. Although it influences deeply the evolution of society, and also has effects not immediately knowable on the environment, the application of technical progress does not typically pass the scrutiny of any public ethics. Dante’s verses come to mind: “Truly often things appear/ that give false matter for doubt/ for the true reasons that are hidden” (Purgatory, XXII).
