Our future on this planet, exposed as it is to nuclear annihilation, depends upon one single factor: humanity must make a moral about-face. At the present moment of history, there must be a general mobilisation of all men and women of goodwill. Humanity is being called upon to take a major step forward, a step forward in civilisation and wisdom. A lack of civilisation, an ignorance of man's true values, brings the risk that humanity will be destroyed. We must become wiser.
~ Pope John Paul II, address to United Nations University, Tokyo
Not sure what my impression of a utopia is, and I don't feel optimistic that we can achieve it (nor that we're necessarily supposed to).
I'll have to think on this one.
