In every part of the universe we observe means adjusted with the nicest artifice to the ends which they are intended to produce; and in the mechanism of a plant, or animal body, admire how every thing is contrived for advancing the two great purposes of nature, the support of the individual, and the propagation of the species.

Several times in Earth's history, rapid global warming occurred, apparently spurred by amplifying feedbacks. In each case, more than half of plant and animal species became extinct. New species came into being over tens and hundreds of thousands of years. But these are time scales and generations that we cannot imagine.
James Hansen
No one is without Christianity, if we agree on what we mean by the word. It is every individual's individual code of behavior by means of which he makes him or herself a better human being than their nature wants to be, if they followed their nature only. Whatever its symbol -- cross or crescent or whatever -- that symbol is man's reminder of his duty inside the human race.
William Faulkner
Thus society is born, as something required by nature, and (because this nature is human nature) as something accomplished through a work of reason and will, and freely consented to. Man is a political animal, which means that the human person craves political life, communal life, not only with regard to the family community, but with regard to the civil community.
Jacques Maritain
If we recognise that every ecosystem can also be viewed as a food web, we can think of it as a circular, interlacing nexus of plant animal relationships (rather than a stratified pyramid with man at the apex)... Each species, be it a form of bacteria or deer, is knitted together in a network of interdependence, however indirect the links may be.
Murray Bookchin
We must start with scientific fundamentals, and that means with the data of experiments and not with assumed axioms predicated only upon the misleading nature of that which only superficially seems to be obvious. It is the consensus of great scientists that science is the attempt to set in order the facts of experience.
