An autopoietic machine is a machine organized (defined as a unity) as a network of processes of production (transformation and destruction) of components which: (i) through their interactions and transformations continuously regenerate and realize the network of processes (relations) that produced them; and (ii) constitute it (the machine) as a concrete unity in space in which they (the components) exist by specifying the topological domain of its realization as such a network.

In this uncertain space between birth and death, especially here at the end of the world in Moonlight Bay, we need hope as surely as we need food and water, love and friendship. The trick, however, is to remember that hope is a perilous thing, that it's not a steel and concrete bridge across the void between this moment and a brighter future. Hope is no stronger than tremulous beads of dew strung on a filament of spider web, and it alone can't long support the terrible weight of an anguished mind and a tortured heart.
Dean Koontz
It is on account neither of God's weakness nor ignorance that evil comes into the world, but rather it is due to the order of his wisdom and the greatness of his goodness that diverse grades of goodness occur in things, many of which would be lacking if no evil were permitted. Indeed, the good of patience would not exist without the evil of persecution; nor the good of preservation of life in a lion if not for the evil of the destruction of the animals on which it lives.
Thomas Aquinas
Industrial production, the flow of resources in the economy, the exertion of military effort in a war, the management of finances --all require the coordination of interrelated activities. What these complex undertakings share in common is the task of constructing a statement of actions to be performed, their timing and quantity (called a program or schedule), that, if implemented, would move the system from a given initial status as much as possible towards some defined goal.
George Dantzig
On the geometric level, we see certain physical elements repeated endlessly, combined in an almost endless variety of combinations... It is puzzling to realize that the elements, which seem like elementary building blocks, keep varying, and are different every time that they occur .... If the elements are different every time that they occur, evidently then, it cannot be the elements themselves which are repeating in a building or town; these so-called elements cannot be the ultimate "atomic" constituents of space.

As far as France is concerned, we are ready to envisage everything that can be done under UNSCR 1441. [...] But I repeat that every possibility offered by the present resolution must be explored, that there are a lot of them and they still leave us with a lot of leeway when it comes to ways of achieving the objective of eliminating any weapons of mass destruction which may exist in Iraq. I'd like nevertheless to note that, as things stand at the moment, I have, to my knowledge, no indisputable proof in this sphere.
