This book offers a comprehensive reflection on the existential condition of the 21st century. A
visionary introduction to existential posthumanism it takes the form of eight meditations of
posthuman self-inquiry. Existential posthumanism embraces the question 'Who am I?' in relation
to: 'Where When and Why are We?'. This journey of self-discovery engages with a wide range of
knowledge and expertise - from ancient paths of wisdom to the latest developments in science
and biotechnologies from Paleolithic times to the futures of radical life extension. The book
declutters the habit of being human: as individuals as societies as a species. Letting go of
the need for anthropocentric mastery and species-specific ambitions the reader emerges
regenerated. Being posthuman in the 21st century entails awareness of inter-being: from our
symbiotic co-evolutions to the rights of Nature from the geological time of the Anthropocene
to the rise of Big Data and artificial intelligence. In ecology biology technology and
ontology the manifold paths of posthuman self-realization will reveal that we are all
co-creators in the existential unfolding: our lives are our ultimate works of art. The Art of
Being Posthuman is a self-help guide to navigate our brave new world.
