Presumably, not having attended graduate school, I exist in a shadowland of ignorance on these matters, hence the perplexity which leads to my inquiry. But suppose that I had attended graduate school, and had earned all of the requisite degrees, with a specialization in political philosophy; suppose further that I had sought positions at a number of institutions, and that the one most interested in my application was dominated by Rawlsians in political philosophy (nothing against Rawls or Rawlsians per se; it's just an example); suppose, finally, that I was not a Rawlsian - and whether I agreed with Nozick, Kekes, or Cohen as against Rawls was immaterial. Would it be licit for the institution, upon an interview, to decline my application, expressly on the grounds that they'd prefer their political philosophy program to be preserved as a warren of Rawlsian scholasticism? That I was not, in view of my differences in philosophical convictions, a good fit?
I should say, in closing, that I've some experience with such tensions between faculty and institutional imperatives, as my first faculty adviser was canned for publishing an anthology of feminist philosophy, in contravention of the institution's guidelines for faculty academic publishing.
Any insight that might dispel my perplexity will be welcomed.
