While Fink and Plotnitsky question Sokal and Bricmont's right to say what definitions of scientific terms are correct, cultural theorists and literary critics Andrew Milner and Jeff Browitt acknowledge that right, seeing it as "defend their disciplines against what they saw as a misappropriation of key terms and concepts" by writers such as Jacques Lacan and Luce Irigaray. However, they point out that Irigaray might still be correct in asserting that 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.
