"Like all human institutions, it [the state] too is mortal. An observer watching the behaviour and listening to the language of British politicians since 1972...would have been reasonably entitled to conclude that the British had become disenchanted with the unique form of government which continues to distinguish them from their continental contemporaries and had resolved to abandon parliamentary self-government under an unwritten constitution in order to be embraced by a single state – and that a unitary, not a federal state – comprising western Europe, the Iberian peninsula and Greece and live forever under treaties interpreted by the European Court. I am not the person best qualified to advise you whether that judgement would be premature, because my own obstinate refusal to countenance the abandonment of parliamentary self-government by the United Kingdom has resulted in my living the life of an Ishmael in British politics since 1972. I will therefore do no more than leave you with some cautionary words of a general character. Nations do tend to behave remarkably like themselves and to revert to past habits even after appearing to have departed from them for sometimes lengthy periods. The most reliable indication of a nation's future behaviour is its history. It would be an exaggeration no doubt, but a venial exaggeration, to say that the history of Britain is the history of British parliamentary self-government."
