Critics of Sokal and Bricmont charge that they lack understanding of the writing they were criticizing. Responses from the scientific community were far more blunt and supportive.

The book's thesis

Fashionable Nonsense examines two related topics:
  • the allegedly incompetent and pretentious usage of scientific concepts by a small group of influential philosophers and intellectuals;
  • the problems of cognitive relativism, the idea that "modern science is nothing more than a 'myth', a 'narration' or a 'social construction' among many others" as seen in the Strong Programme

Incorrect use of scientific concepts versus scientific metaphors

The stated goal of the book is not to attack "philosophy, the humanities or the social sciences in general...[but] to warn those who work in them (especially students) against some manifest cases of charlatanism." In particular to "deconstruct" the notion that some books and writers are difficult because they deal with profound and difficult ideas. "If the texts seem incomprehensible, it is for the excellent reason that they mean precisely nothing."

The book includes long extracts from the works of Jacques Lacan

Sokal and Bricmont claim that they do not intend to analyze postmodernist thought in general. Rather, they aim to draw attention to the abuse of concepts from mathematics and physics, subjects they've devoted their careers to studying and teaching. Sokal and Bricmont define abuse of mathematics and physics as:
  • Using scientific or pseudoscientific terminology without bothering much about what these words mean.
  • Importing concepts from the natural sciences into the humanities

The postmodernist conception of science

. Bruce Fink (who produced the first complete English translation of Jacques Lacan's Ecrits) offers a critique in his book Lacan to the Letter, where he accuses Sokal and Bricmont of demanding that "serious writing" do nothing other than "convey clear meanings". Fink asserts that some concepts which Sokal and Bricmont consider arbitrary or meaningless do have roots in the history of linguistics, and that Lacan is explicitly using mathematical concepts in a metaphoric way, not claiming that his concepts are mathematically founded. He takes Sokal and Bricmont to task for elevating a disagreement with Lacan's choice of writing styles to an attack on his thought, which, in Fink's assessment, they fail to understand. Fink says that "Lacan could easily assume that his faithful seminar public... would go to the library or the bookstore and 'bone up' on at least some of his passing allusions".

While in the book, Sokal and Bricmont acknowledge that they "do not always understand the rest of these authors' work," Fink goes further and accuses them of having "no idea whatsoever what Lacan is up to," while himself noting that "even those of us who devote a lot of time and energy to deciphering Lacan's work — become infuriated with him for it at one point or another."

This latter point has been disputed by Arkady Plotnitsky (one of the authors mentioned by Sokal in his original hoax

). Plotnitsky says that "some of their claims concerning mathematical objects in question and specifically complex numbers are incorrect," specifically attacking their statement that complex number

s "have nothing to do with one another". Plotnisky here defends Lacan's view "of imaginary numbers as an extension of the idea of rational numbers—both in the general conceptual sense, extending to its ancient mathematical and philosophical origins ... and in the sense of modern algebra." The first of these two senses refers to the fact that the extension of real number

: "From the irrationals are born the impossible or imaginary quantities whose nature is very strange but whose usefulness is not to be despised." However, with regard to the second sense, which Plotnisky describes by stating that "all imaginary and complex numbers are, by definition, irrational," mathematicians generally agree with Sokal and Bricmont in not taking complex numbers as irrational

. Indeed, the concept of rational numbers has been extended into the complex domain to include Gaussian integer

Plotnitsky goes on, however, to agree with Sokal and Bricmont that the "square root of –1" which Lacan discusses (and for which Plotnitsky introduces the symbol ) is not, in spite of its identical name, "identical, directly linked, or even metaphorized via the mathematical square root of –1

," and that the latter "is not the erectile organ." Lacan's assignment of new meanings to standard mathematical terms in this way, though supported by Plotnitsky as valid within the context of his work, is of course one of the things which Sokal and Bricmont object to.

 is a "masculinist" equation, since "the social genealogy of a proposition has no logical bearing on its truth value." In other words, gender factors may influence which of many possible scientific truths are discovered. They also suggest that, in criticising Irigaray, Sokal and Bricmont sometimes go beyond their area of expertise in the sciences and simply express a differing position on gender politics.
