Of course Thatcher famously slammed down a copy of Hayek's "The Constitution of Liberty" and declared "this is what we believe", significantly not using the first person singular. Thatcher is the Leader, Hayek the Master.

I wonder what book the Left* would slam down now, in an equivalent constitutive act.

*by which I mean of  course the redundant/ fascist/ totalitarian/ Leninst/ social-democratic etc Left.
