"Philosophy of the World is the sickest, most stunningly awful wonderful record I've heard in ages: the perfect mental purgative for doldrums of any kind," wrote Debra Rae Cohen for Rolling Stone in a review of the 1980 reissue. "Like a lobotomized Trapp Family Singers, the Shaggs warble earnest greeting-card lyrics (...) in happy, hapless quasi-unison along ostensible lines of melody while strumming their tinny guitars like someone worrying a zipper. The drummer pounds gamely to the call of a different muse, as if she had to guess which song they were playing — and missed every time." "Without exaggeration," Chris Connelly wrote in a later Rolling Stone article, "it may stand as the worst album ever recorded." An article for The New Yorker describes how one internet reviewer described the album as "hauntingly bad".
