As an academic studying philosophy, semiotics, and culture, Eco divided critics as to whether his theorizing should be seen as brilliant or an unnecessary vanity project obsessing over minutiae, while his fiction writing stunned critics with its simultaneous complexity and popularity. In his 1980 review of "The Role of the Reader", philosopher Roger Scruton, attacking Eco’s esoteric tendencies, writes that, "seeks the rhetoric of technicality, the means of generating so much smoke for so long that the reader will begin to blame his own lack of perception, rather than the author’s lack of illumination, for the fact that he has ceased to see." In his 1986 review of "Faith in Fakes" and "Art and Beauty in the Middle Ages", art historian Nicholas Penny, meanwhile, accuses Eco of pandering, writing "I suspect that Eco may have first been seduced from intellectual caution, if not modesty, by the righteous cause of ‘relevance’ (a word much in favour when the earlier of these essays appeared) – a cause which Medievalists may be driven to embrace with particularly desperate abandon."
