What is understanding anyway? Some of the most famous thinkers, from ancient Greece to Kant and Heidegger, have asked themselves this question. What led to the development of the human mind? Dorin Gabriel Tilinca sets out to find the very first principles on which comprehensibility, i.e., intelligence, is based. He demonstrates that these first principles must be universal, the same for all possible intelligent beings, regardless of their biological nature, because they are the criteria that shape both the mind and reality itself. Where other great philosophers have failed to provide adequate answers to this fundamental question, Dorin Gabriel Tilinca goes further and arrives at some astonishing conclusions.
