Charles Darwin's The Origin of Species connected humans with nature, but since then biology has been stalled, unable to address the dilemma of the human condition - our capacity for good and evil. If the universally accepted moral ideal is to be co-operative, loving and selfless, why are we humans so competitive, aggressive and selfish? Ignorance about ourselves, about why we behave the way we do, has been an immense affliction. In fact, without being able to understand and to reconcile our contradictory behaviour, we have had little choice but to block out the whole depressing subject and live in a state of denial. Biologist Jeremy Griffith argues in this Australian bestseller that only by understanding why we have become less than ideally behaved can we at last safely face the truth about our condition and learn to live in full harmony with ourselves and with others. Life isn't driven by a competitive model of 'survival of the fittest', but rather by a drive towards greater co-operation and integration. With the accumulated knowledge of science we can finally understand how, despite appearances, we have been a part of this process, and it is this liberating insight which finally brings about the maturity of the human race.
