John Gray, writing in The New Statesman, suggests as much but also examines what we need to do about it.
Accepting that this is a post-liberal moment does not imply that we should give up on values of freedom and toleration. Quite the contrary: the task at hand is securing the survival of a liberal way of life. But the greatest obstacle to that end, larger even than the hostility of avowed enemies of liberalism, is a liberal ideology that sees state power as the chief threat to freedom. Liberal societies have a future only if the Hobbesian protective role of the state is firmly reasserted. Balancing the claims of liberty against those of security will never be easy. There are many conflicting freedoms, among which political choices must be made. Without security, however, freedom itself is soon lost.
Gray offers what should be a word of caution to our current Liberal government.
