Liam Kofi Bright at The Sooty Empiric:
Those of us in the contemporary academy who are not liberals ought give an account of why not. This asymmetric burden falls on us, I believe, because the presumption is so strongly that one does fit within the broad confines of liberalism that if one does not explicitly identify out and explain why one has done so then two things may occur. First, people may reasonably presume on statistical grounds that your politics are as such and engage with you with this in mind. This will make intellectual back and forth, the lifeblood of our profession, frustratingly congealed — always having to go back and check unstated presuppositions half way through a conversation, never getting to the meat of things. Second, one allows whatever thinking one does to accrue to the greater glory of an ideology you reject. Since the natural presupposition is that whatever insights you achieve have been achieved through the lens of liberal ideology, it will seem that whatever is good in your work is evidence that liberalism can support and sustain that good. Since, by hypothesis, I am addressing myself to people who are not liberals, this is presumably something you wish to avoid.
