In an ideal world, a young man should not be an ironical person. At that age, irony prevents growth, stunts the imagination. It is best to start life in a cheerful and open state of mind, believing in others, being optimistic, being frank with everyone about everything. And then, as one comes to understand things and people better, to develop a sense of irony. The natural progression of human life is from optimism to pessimism; and a sense of irony helps temper pessimism, helps produce balance, harmony. But this was not an ideal world, and so irony grew in sudden and strange ways.
– Julian Barnes, The Noise of Time (2016)
