Close friends and longtime readers of Hesse criticized the novel for its perceived lack of morality in its open depiction of sex and drug use, a criticism that indeed remained the primary rebuff of the novel for many years.[4]
American novelist Jack Kerouac dismissed it in Big Sur (1962), though popular interest was renewed in the 1960s – specifically in the psychedelic movement – primarily because it was seen as a counterculture book, and because of its depiction of free love and explicit drug use.
