From a dialogue on the strange attractor with Sergio Stagnaro, Henri Poincaré and John Henry Newman, it emerges that deterministic chaos intimately recalls the secret of life, which is essentially order, in-formation, harmony, beauty, complexity, connections. However, all this must be seen in a dynamic key, where structure and function are two poles of the same equation, and whose equilibrium are higher, complex orders, aroused by an unknown and invisible law, a generative law, which incessantly acts and regulates the complex order ( deterministic chaos) and its connections (entanglement). However, these topics are addressed in a simple and direct way, looking at the nature that surrounds us: the bees, the ants, the trees, the clouds, the mountain lakes, the jagged coasts, the mountains. We thus discover that the natural order outside of us has similarities and connections with the natural order within us, where however Grace acts, the divine order, from which life alone originates. Having revealed this, we finally discover what the secret is to choosing life, as the book of Deuteronomy urges us to do.
