First words Chapter I - Unexpected complications on the way to the unthought Boldly risking a step into the unknown Another place, another time? French poems. Wandering through the naves of our thermonuclear cathedrals Nanotechnologies of the first humans From impressionistic dots to thick lines A thousand millennia of Anatolian transgressions Mythologies of the first modern humans Human beings known as shadows A first contact with inverted values Making the best of a bad job Chapter II - The last Neanderthal? An improbable encounter The last Neanderthal! The imaginary realms lying between two worlds Upside down. Thorin is one hundred and five millennia old! From rivers that unite to rivers that separate Light beyond the unknown lands A last Neanderthal, in his place? Touching the unquantifiable From flesh to bone The mind in matter and the gaze versus reality Mental processes on the edge of the hole For a few centimetres too many The first of the last contacts? Three waves breaking against the intellectual Titanic Genetic surprises The stone ship Gone with the Wind The oases of the sea A simplified world Chapter III - How do humans die? A grammar between two worlds Apology for the stifled No one escapes the sphere Men from the sky and white opossums The gods must be crazy Acculturation and the implosions of the spheres Men in the trees The gods must be crazy 2.0 In our disordered memories The times of extinction Epilogue. This is how humans die Acknowledgements.
