This is the flexible Conservatism of Benjamin Disraeli, a 19th-century prime minister, combining his awareness of the needs and votes of the lower classes with the gradualism of Edmund Burke, who articulated Tory alarm at the French Revolution.
Recognising this problem, the SNP now markets a sort of independence lite or 2.0, designed to sound reassuringly innocuous, in which Scotland keeps the queen, the pound and its military bases (a gradualism that suits Mr Salmond more than his party's Braveheart wing).
