The mirror of Dionysus is the meeting place between a biologist (Redi) and a philosopher (Sini), who debate and question, from different yet integrated perspectives in the common effort of seeking the truth, on the most tangible theme of life: corporeality. A common approach to the demands of life, refusing to end in mere observations on the existing (that is something that is), courageously accepting instead the challenge of questioning its meaning (that is why something is).
