A battle over pleasure has broken out. On Twitter and in the pages of scientific journals, psychologists, neurologists and neuroscientists are forging alliances over the question of whether pleasure we get from art is somehow different from the pleasure we get from candy, sex or drugs.

The debate was ignited by an opinion piece titled “Pleasure Junkies All Around!” published last year in the journal Proceedings of the Royal Society B. In it, Julia F. Christensen, a neuroscientist at the The Warburg Institute at the University of London who studies people’s responses to dance choreography, argued that many of us have been turned into “mindless pleasure junkies, handing over our free will for the next dopamine shoot” provided by social media, pornography and sugar.

She offered up an unconventional solution: art, which she says engages us in ways these other pleasures do not and can “help overwrite the detrimental effects of dysfunctional urges and craving.”

The paper struck a nerve with some of her fellow art and pleasure researchers, who published a rebuttal last month in the same journal. The idea that the way that art engages the brain is somehow special has been around for far too long and it is time to kill it off once and for all, they insist.
