A couple of excerpts from Ship of Fools: How Stupidity and Corruption Sank the Celtic Tiger (2009), a fine polemic by the Irish critic and author Fintan O’Toole:
One of the great strengths of Irish culture [is] its capacity for double-think. For a range of reasons – the simultaneous existence of paganism and Christianity, the ambiguous relationship of indigenous society to a colonial power, the long experience of emigration – Irish culture developed a particularly strong capacity for operating simultaneously within different mental frameworks. This is one of the reasons for the rich inventiveness of Irish artistic life and for much of the humour, teasing and wordplay that enliven social interaction. Irish double-think is wonderfully summed up by the old woman in the 1930s who, asked by Sean O’Faolain if she believed in the little people, replied, ‘I do not, sir, but they’re there.’
Much of this is of course unprovable (and unfalsifiable), and you could probably make a case for the same capacity for doublethink in other countries. But O’Toole’s ideas are, as always, food for thought.
