Howard Jacobson explains why he dislikes the narcissism of the selfie.

"It's always possible that there's some Rembrandt of the selfie out there, using his 'phone to investigate the ravages of age, the incursions of melancholy, and even the psychology of self-obsession itself, but commonly the selfie performs a less self-critical function, putting the self at the centre of everything we see, marking the landscape with our faces, as though the only possible interest of the outside world is that we're in it."
