Gould argues that Snow reverses his position in 1963 with The Two Cultures: A Second Look and acknowledges that the original motivating assumption of "dichotomous parsing of intellectual life into contrarian literary and scientific camps" was not a true representation and Snow was sorry for having failed to recognize a third culture in the continuous spectrum of intellectual life.
Gould criticizes Snow's initial assumption of a binary division between literary and scientific cultures in "The Two Cultures: A Second Look," arguing that it is inaccurate and Snow should have recognized a broader, more nuanced understanding of intellectual life.
