Postmodernism precludes philosophical justifications for democracy. This undermines the role of philosophy of education and leaves us with weaker reasons for educational democracy than we need. If the ‘postmodern challenge’ is as Wilfred Carr conceives it, Jürgen Habermas meets that challenge. His work rests on neither Enlightenment essentialism nor foundationalism. Habermas can accept and explain that consciousness is historically and socially situated in discourse, yet still argue to the possibility of emancipation. I defend his conception of rationality from charges of (...) essentialism. Rational thinking can critique its own specific forms, so superior forms of rationality remain universalisable by rational means. A historicising account of such critique avoids situationist relativism. These considerations justify educational democracy and preserve a role for philosophy of education. (shrink)
