From Georg Simmel

“The enourmous supply of people willing to engage in, and often gifted for, intellectual production, a supply favoured by economic factors, has led to a self-ascribed valorizing of all scholarly work, whose value is indeed often only a convention, almost a conspiracy of the scholarly caste; all this has led to an uncannily fertile inbreeding of the scholarly mind, the offspring of which, both inwardly and in the sense of having a wider effect, is infertile.” (Der Begriff und die Tragödie der Kultur)
