According to Michel Serres, a process of 'hominescence' has taken place throughout human history. Hominescence can be described as a type of adolescence; humanity in a state of growing, a state of constant change, on the threshold of something unpredictable. We are destined never to be the same again but what does the future hold? In this innovative and passionately original work of philosophy, Serres describes the future of man as an adolescence, transitioning from childhood to adulthood, or luminescence, when a dark body becomes light. After considering the radical changes that humanity has experienced over the last fifty years, Serres analyzes the new relationship that man has with diverse concepts, like the dead, his own body, agriculture, and new communication networks. He alerts us to the consequences of these changes, particularly on the danger of growing inequalities between rich and poor countries. Should we rejoice in the future, ignore it, or even dread it? Unlike other philosophies that preach doom and gloom, Hominescence calls for us to anticipate the uncertain light of the future.
