'The intention of this book was to put a scientist and a philosopher face to face and spark a dialogue between them on neuroscience, on their results and projects, and their ability to carry out a debate on ethics, its norms, and on peace. In France, ideas are rarely openly discussed. Serious debates are too often hindered by dogmatic statements, one-sided criticisms, incomprehensible discussions and glib mockery, with little or no thought for the solidity of the arguments, which aim only to appear plausible or worthy of being argued, rather than convincing. A totally free and open dialogue between a scientist and a philosopher is necessarily a highly unusual experience for both.'
