Perhaps the most effective virtue for a liberal is inconsistency. We do not believe that the state is always the right solution, or that the market invariably has the answer. We know it depends on circumstance. And – this is the crucial point – circumstances change. There are times when the state needs to intervene, and there are periods when its power needs to be constrained. If we ask when intervention is necessary, the simple response is when our society is in crisis – when inequality is so stark that local or charitable solutions can not be sufficient. The contention of Reinventing the State is that we are at one of those moments of crisis. And, what is more, we have to battle not only with the old enemies of poverty, lack of opportunity, unequal life expectancy but also with a new foe: climate change and the destruction of our planet. To my mind, this challenge is also the impetus to a new perspective on our ideology.
Does this matter? I think it does, for two reasons. First, because it has relevance beyond that of the environment, providing a longer-term perspective on some of the other issues that we face. Previous generations of liberals, including the New Liberal thinkers of the early twentieth century, had confidence in a concept of progress. In that mindset, future generations could be expected to enjoy an ever better existence which, perhaps, meant that their welfare did not have to be of concern now. Progress is the god that died; we think beyond our own graves with a sense of anxiety, not confidence. But in protecting the heritage we leave, we face another problem and that is the second reason why this matters. We have to ask ourselves how far the ‘not-yet-living’ can be used as a trump card? How do we ensure that our stewardship for future generations does not create unacceptable brakes on our freedom in our own lifetimes?
