'It's time to acknowledge', writes Will Self, 'that we don't really feel nostalgia at all - only something far more worrying and debilitating: a condition I've named no-stalgia'.

Will argues that the West is particularly in thrall to rose-tinted nostalgia and looks to Japan - and its concept of 'mono no aware' - as an alternative and healthier way of thinking about the past.
