Conventional physics deals only with closed systems, i. e. systems which are considered to be isolated from their environment... However, we find systems which by their very nature and definition are not closed systems. Every living organism is essentially an open system. It maintains itself in a continuous inflow and outflow, a building up and breaking down of components, never being, so long as it is alive, in a state of chemical and thermodynamic equilibrium but maintained in a so-called steady state which is distinct from the latter.

O God, enlarge within us the sense of fellowship with all living things, even our brothers, the animals, to whom Thou gavest the earth as their home in common with us. We must remember with shame that in the past we have exercised the high dominion of man with ruthless cruelty so that the voice of the earth, which should have gone up to thee in song, has been a groan of pain. May we realize that they live, not for us alone, but for themselves and for Thee and that they love the sweetness of life.
Basil of Caesarea
God always was, and always is, and always will be. Or rather, God always Is. For Was and Will be are fragments of our time, and of changeable nature, but He is Eternal Being. And this is the Name that He gives to Himself when giving the Oracle to Moses in the Mount. For in Himself He sums up and contains all Being, having neither beginning in the past nor end in the future; like some great Sea of Being, limitless and unbounded, transcending all conception of time and nature, only adumbrated [intimated] by the mind, and that very dimly and scantily.
Gregory of Nazianzus
The briefest definition of the Islamic order defines it as a unity of religion and law, upbringing and power, ideal and interest, the spiritual community and the state, willingness and force... An Islamic society without an Islamic authority is incomplete and without power; Islamic government without Islamic society is either utopia or violence. Generally speaking, a Muslim does not exist as a sole individual. If he wishes to live and survive as a Muslim, he must create an environment, a community, a system.

It is the foundation of my Government's mission to build a modern, compassionate and just society in Scotland. A society where we not only meet our immediate needs, but ensure that all can share in the benefits of prosperity. And a Scotland that is ever conscious of its global responsibilities - promoting peace, supporting international development and protecting our environment. Building this society and instilling these values in our population requires the highest standards of teaching in our education system - and a strong ethical dimension.

For a hundred and fifty years or so democracy, or something like it, could flourish safely. The issues were such as to be settled without disaster by votes of common men, befogged and ignorant as they were. But now, if the race is simply to stay alive, political decisions depend on real knowledge of such things as nuclear physics, planetary ecology, genetic theory, even system mechanics. They aren't up to it, Joe. With goodness and more will than they possess less than one in a thousand could stay awake over one page of nuclear physics; they can't learn what they must know.
