I have long wondered how to use the transfinite numbers as a scale of entropy. The problem has been that if we take something like a gas and reduce it to a liquid we are thermodynamically reducing its entropy, so from the point of view of the gas I once was out there in the stars but we can take the view that the information carried by a point is equal to the entropy of the space from which it is chosen, so that from this point of view my information content (and reputed entropy) is equal to the entropy of the gas from which I came. Or words to this effect [appropriate to information theory rather than heat engineering].
Some thoughts on representations and their transformations in the mental processing pipeline.
We look for a unique and invertible representation which also gives design for action, being transformed and differently coded as it flows through the pipeline making maximum use of the sensory input to achieve effective action. We may be able to apply a Lagrangian to the relationship between the input and output to be optimized by selective pressures.
[page 281]
Semantic representation carries a dimension of intent, I want to catch this chicken to eat.
We think in terms of an unbroken pipeline from sense to muscle, in football, as in philosophy, watching the play and responding, listening to the lectures and writing. As well as data immediately collected by sensation the processing pipeline has structural constraint and is also affected by memory, habit and experience. There are fixed and variable elements in the process, varying from very stable structures like bones and joints to ephemeral synaptic weights which can change in milliseconds.
Features of philosophical pipeline process from lecture to essay are reflected in literary allusions like the white whale and boiling frogs. Herman Melville: Moby-Dick
We can see social cognitive diseases like murdering witches, refugees and anyone who is different.

Causal representation must account for the fact that deception is a very important input to fitness [and places an extra load on mind since the deceiver must maintain two or more representations of the situation in hand].
Everything represents itself and depending on context may represent an infinity of other things.

gets tested until someone takes the trouble, and some ideas, like the Higgs boson, have taken tens of billions of dollars in salaries and equipment to finally bring to the acid test. If I was being paid to dream up my theologcal dream I might be in for fifty years at $100k or so, say 5 million and it still has a long time to go, although I am hoping to get the philosophy department at Adelaide U to help me, which might speed things up a bit.
Religion motivates enormous developments (cathedrals) and enormous disasters (religious wars). It is necessary to redirect this religious feeling toward the real God.

Naturalizing morality: we operate in two epistemological spaces, pragmatic survival [business] and scientific rationalism [academia]. The pragmatic space tends to be zero sum, given the fixed foundation of resources upon which the evolutionary system is built, so it gives us the competitive element that lies at the root of rape, plunder, genocide and so on. Scientific rationalism, on the other hand, which principally operates in the realm of religion [and theology] recognises the positive sum that arises from cooperation with one another, with love of God, love of on another and creative elements in general, including technology for greatly increasing the physical substrate available for our species (at the cost of other species), health care and all the technological devices that we have developed to widen our horizons and increase out quality of life.

Now that I have reached a comfortable old age and am sitting in my philosophical armchair with my hot water bottle on my knee and a beer by my side I have time to reflect on my rather random walk through life. Earth has changed a lot on the last 75 years, and perhaps the biggest influence was the second world war which not only changed the political map but put science at the forefront of making war, with the effect of making it so destructive as to be useless for its ancient function of increasing the fitness of one community by plundering another. A consequence of this has been the globalization of business which has become in many ways simply plunder by other means. What to do about all this? I have never really had any power or wealth, but I do have the ambition of emphasizing the power of cooperation in the context of a divine world whose real power is the power of networks and cooperation. I have two essays to finish tomorrow, both concerned with the role of evolution. What I am trying to emphasize is not so much the survival of the fittest side of nature red in tooth and claw but the cooperative forces that have led t multicellular creatures and the development of human societies. Here science must overcome divisive ideologies if we are to live in peace.
[page 284]
My contribution to the future, apart from my beautiful children will be, I hope, a comprehensive theological picture of peaceful and sustainable life within God, the heart of my MPhil project. These essays have caused me not a little grief but I can now see the way forward to explaining the power of evolution through cooperation based on shared protocols, ie symmetries. Whether I can make this point in the short space of an essay is a further question.
In a way I am a bit bored because I have said all I want to say and am waiting for something new to turn up in my consciousness. I can control a lot of my conscious content because it is pretty much a cognitive representation of all my sensations at this moment from the warm hot water bottle to the taste of my beer and the pleasing screen on my computer which says my shares just went up $949 [after a few months in the doldrums]. I can make myself conscious of these and millions of other things just by looking and remembering but what really beats the boredom for me and comes loaded with excitement [is new and unexpected insight]. Yesterday I was trying to write about the thermodynamics of evolution, Physical thermodynamics tells us that systems are stable when their entropy is at a maximum and they are in thermal equilibrium. Due to solar radiation, however, the surface of the earth is far from thermal equilibrium, as we see from the rapid changes in weather, some very big like cyclones. Yet life, although far from equilibrium, is stable. I attribute this to error free communication in living networks and yesterday I noticed (perhaps for the first time) the fact that Shannon's theory of communication predicts that completely error free
[page 285]
communication requires that messages be coded in blocks of infinite length which requires codecs of high complexity. The virtuous circle is that complex systems require complex codecs for their stability, something which . . . can be provided by complex [structures], so complexity can bootstrap itself in the way we see in [Teilhard] de Chardin's complexification. That was yesterdays insight, but what is today's? I am still waiting. Tomorrow I will write it up for my evolution essay, and I hope to wake up in the morning with a new idea.

The key word in the definition is information. This definition, like all definitions of life, is relative to the environment. My reference system is the natural environment we find on this planet.

Marr, David, Patrick White: A Life, Knopf 1992 Editorial review from Library Journal : 'From Library Journal
An admirably readable biography of the Nobel Prize-winning author of Voss , The Tree of Man , and many other books, this work is full of detail on White's family and prosperous background, the events and people in his life, his writing habits, his religious beliefs, his cantankerousness and temper, his causes and doubts, his attraction to the theater, and much more. White helped Marr gain access to people and material, even authorizing him to collect his letters, "the backbone of this book." Marr deals intelligently with important issues (among them, White's rootedness in and dissatisfaction with Australia, his sense of himself as an outsider, his relation to his mother, and, in particular his homosexuality, which White considered central to his novelistic and theatrical ability), avoiding psychoanalytical speculations and other intrusions. White reviewed the book shortly before he died, finding it "so painful he often found himself reading through tears. He did not ask Marr to change a line."' Richard Kuczkowski

Melville, Herman, Moby-Dick, Bantam Classics 1981 'First published in 1851, Herman Melville’s masterpiece is, in Elizabeth Hardwick’s words, “the greatest novel in American literature.” The saga of Captain Ahab and his monomaniacal pursuit of the white whale remains a peerless adventure story but one full of mythic grandeur, poetic majesty, and symbolic power. Filtered through the consciousness of the novel’s narrator, Ishmael, Moby-Dick draws us into a universe full of fascinating characters and stories, from the noble cannibal Queequeg to the natural history of whales, while reaching existential depths that excite debate and contemplation to this day.

Sperner colorings have been used for effective computation of fixed points, in root-finding algorithms, and are applied in fair division (cake cutting) algorithms.
