Life - All Our Yesterdays and Tomorrows, is a literary project of unusual scope. It may best be considered as a philosophical work, although even that categorisation does not adequately describe the enormous breadth of coverage of this work. The concept of life is explored in depth, from the beginnings of geological life, through the emergence of biological life and the arrival of human kind. The human condition is then considered from many perspectives, with both an historic and contemporary view taken in relation to several important factors that have shaped humanity over the millennia. Our current global situation is considered, with many insights as to our current position as a civilisation and how we have reached this point. A view is then developed as to the likely future of our species in relation to the natural world, taking our past behavioural trends into account and positing various future scenarios. It is a work which will inspire a good deal of critical thinking about the future of humanity and what it means to be a human being.
