Once the threshold is crossed when there is a self-sustaining level of life in space, then life's long-range future will be secure irrespective of any of the risks on Earth (with the single exception of the catastrophic destruction of space itself). Will this happen before our technical civilisation disintegrates, leaving this as a might-have-been? Will the self-sustaining space communities be established before a catastrophe sets back the prospect of any such enterprise, perhaps foreclosing it for ever? We live at what could be a defining moment for the cosmos, not just for our Earth.

Only within the 20th Century has biological thought been focused on ecology, or the relation of the living creature to its environment. Awareness of ecological relationships is - or should be - the basis of modern conservation programs, for it is useless to attempt to preserve a living species unless the kind of land or water it requires is also preserved. So delicately interwoven are the relationships that when we disturb one thread of the community fabric we alter it all - perhaps almost imperceptibly, perhaps so drastically that destruction follows.
Rachel Carson
I hear Republicans and Libertarians and so forth talking about property rights, but they stop talking about property rights as soon as the subject of American Indians comes up, because they know fully well, perhaps not in a fully articulated, conscious form, but they know fully well that the basis for the very system of endeavor and enterprise and profitability to which they are committed and devoted accrues on the basis of theft of the resources of someone else. They are in possession of stolen property. They know it. They all know it. It's a dishonest endeavor from day one.
Ward Churchill
Now more than ever before, the people are responsible for the character of their Congress. If that body be ignorant, reckless, and corrupt, it is because the people tolerate ignorance, recklessness, and corruption. If it be intelligent, brave, and pure, it is because the people demand these high qualities to represent them in the national legislature... If the NEXT CENTENNIAL does not find us a great nation... it will be because those who represent the enterprise, the culture, and the morality of the nation do not aid in controlling the political forces.
James A. Garfield
Dialectical logic undoes the abstractions of formal logic and of transcendental philosophy, but it also denies the concreteness of immediate experience. To the extent to which this experience comes to rest with the things as they appear and happen to be, it is a limited and even false experience. It attains its truth if it has freed itself from the deceptive objectivity which conceals the factors behind the facts - that is, if it understands its world as a historical universe, in which the established facts are the work of the historical practice of man.
Herbert Marcuse
Prayer, fasting, vigils, and all other Christian practices, however good they may be in themselves, certainly do not constitute the aim of our Christian life: they are but the indispensable means of attaining that aim. For the true aim of the Christian life is the acquisition of the Holy Spirit of God. As for fasts, vigils, prayer and almsgiving, and other good works done in the name of Christ, they are only the means of acquiring the Holy Spirit of God. Note well that it is only good works done in the name of Christ that bring us the fruits of the Spirit.
