One of the concepts which deserves particular attention by philosophers of the 21th century is that of life and, more specifically, that of human life. Because life on Earth is limited, mankind has historically relied on religion for its promise of salvation and an afterlife.Yet, recently, people have been relying on alternative institutions, such as the state or market, for answers to their questions about the limited nature of human life. With the rise of dependence on such instituions comes the rise of new questions: are the state and market responsible for defining the meaning of life and for providing adequate answers to the suffering and death that afflict humankind? Can the state make use of technology and scientific knowledge in order to regulate population according to its objectives? Is there any ethical limit to the experimentation with the different phases of human life? Is it possible to preserve a sacral sphere for human life? This book provides extensive reflection and possible solutions to these perplexities.
