To the impartial observer Britain does not appear to have any mountains. Yet the British invented the sport of mountain climbing and for two periods in history British climbers led the world in the pursuit of this beautiful and dangerous obsession. Unjustifiable Risk is the story of the social, economic and cultural conditions that gave rise to the sport, and the achievements and motives of the scientists and poets, parsons and anarchists, villains and judges, ascetics and drunks that have shaped its development over the past two hundred years. Today's climbers would be instantly recognisable to their Victorian predecessors, with their desire to escape from the crowded complexity of urban society and willingness to take "unjustifiable" risk in pursuit of beauty, adventure and self-fulfilment.
