Where is the dividing line, if it indeed exists, between good and evil, between that which is legitimate and that which is illicit? Biology, morality, religion, sex, environment: do there remain any insuperable boundaries in these spheres of life? The relentless development of science will lead to genetically modified humans, capable of manipulating life and death and solving the mysteries of matter and the cosmos. What are the underlying risks? This book addresses urgent challenges that have to do with thinking about limits, telling them apart, deciding which ones’ validity needs to be re-affirmed, as well as exploring our desires, goals and margins of freedom.
