“The cliché is that ‘power corrupts’ but it would be more accurate, and more telling, to rephrase this as ‘the ability to define reality corrupts’! If I have the power to define reality than I am pretty much untouchable; if I have the power to say what reality is and what it isn’t then I can get away with just about anything. How can I get caught out when ‘everything I do is right’ (or when ‘everything I do is eminently justifiable’) and you can be sure that everything I do will be excused in this way if I’m the one in charge of the ‘official validation procedure’!”
