It's all a question of emphasis. We have all the qualities within each of us - to be transient and to settle, for example. We are never all one thing or all another. It's just a case of which bit we emphasise at any particular time. Political parties supposedly divide into left and right, but it's more a difference of emphasis, than a clearcut divide between them. Cameron seems to be aware of this, and he cleverly draws from all sides of the argument.
The coming of environmentalism doesn't need to be presented as the end of economics. We've had 'the end of history' and look where that got us (Iraq). To hear Zac Goldsmith sounding off against economics to make way for the environment is a mistake. It is only through economics that technology will come to the fore, and remove the bad technologies that we currently have. Caring and economics are not mutually exclusive.
The arrival of the new is always impossible. We only have things like the jet engine and computers because of the push that wars have given us. We need to find ways to adavance technology fast without the resistance that always stands in its way. It is nuts for Zac Goldsmith to be providing a major source of resistance to the new technologies that we need. We cannot go back to the stone age. We must push forward and improve our world, economically, scientifically and spiritually - all together. Redwood is just as key as Goldsmith and IDS in setting the right values. None must be allowed to claim to represent the whole picture.
