As a millennial who graduated from college in 2010, in the lingering wake of the financial crisis, the cultural critic Kyle Chayka haltingly admits to being a minimalist, but only “by default.”

When he began writing “The Longing for Less,” he was put off by how minimalism had become commodified — a smug cure-all that countered late-capitalist malaise with self-help books by Marie Kondo and seasonal pilgrimages to The Container Store. His own minimalism was a consequence of living as an underpaid writer in New York: No basements and no closets meant no storage space for stuff.

But those two kinds of minimalism — sleek lifestyle branding and enforced austerity — don’t quite convey the enormousness of the subject Chayka explores in this slender book. Delving into art, architecture, music and philosophy, he wants to learn why the idea of “less is more” keeps resurfacing. He sees it as a shadow to material progress, a reaction to abundance, a manifestation of civilization’s discontents. He remembers growing up in a three-story house with a two-car garage in rural Connecticut and feeling mildly oppressed by “detritus scattered at random all over the place.”

The book itself is like an exercise in decluttering, as Chayka cycles through different ideas in order to find those he wants to keep. An inevitable section on Kondo doesn’t find much to commend in her approach, deeming it a force for homogeneity and, like comparable books in the genre, “an exercise in banality.” For Chayka, Kondo’s method clearly doesn’t spark joy.
