In the 1950's and now domiciled in the United States, Hayek perceived the need for a more systematic popular treatment of the case for liberal democracy than the arguments he had advanced in ''Serfdom''; the result was 1960's magisterial three-part ''The Constitution of Liberty''.  Although this new work, weighing-in at 350 pages plus extensive endnotes, could not hope to equal the success of his earlier book, nevertheless Hayek's ''Constitution'' had huge influence (especially in the UK, somewhat ironically) becoming, along with Popper's ''The Open Society and its Enemies'', a founding text of Thatcherism.  "This is what we believe," affirmed a stern-faced Margaret Thatcher at a 1975 opposition meeting, according to John Ranelagh - holding up her copy just long enough for the attendees to read the title before banging it down emphatically onto the table.
