Incomplete Nature Part 19

Weak emergentism: The argument that although in emergent transitions there may be a superficially radical reorganization, the properties of the higher and lower levels form a continuum, with no new laws of causality emerging. Often a.s.sociated with epistemological emergentism because it is attributed to incomplete knowledge of the critical causality

NOTES.

CHAPTER 0: ABSENCE.

1. With thanks to Charles Seife, the author of Zero: The Biography of a Dangerous Idea, from which I take this chapter number idea and the quote from Tobias Dantzig's Number at p. 35.

2. This term was suggested to me by my longtime colleague Tyrone Cashman. Though the term takes liberties with the flexibility of the English language, I think that its somewhat cavalier form is compensated by the way it focuses attention on this one most central feature of these troublesome phenomena. I will resist the obvious tendency to call this metaphysical paradigm absentialism, because as will soon be evident, it is an explanation of the emergent and dynamical character of the processes generating these phenomena that is my primary goal.

4. A calculating device made with movable beads arranged on strings, originally devised in the Middle East, but spread eastward as far as China, where it is still in use as a calculation aid.

5. For a trivial example, consider that since 0 x 1 = 0 and 0 x 2 = 0, it follows that 0 x 1 = 0 x 2. We can then divide each side by zero (which is the disallowed operation) and cancel 0/0 in each (which for any other number equals 1, but is undefined for 0), and simplify to get 1 = 2.

6. Prior to the work of the eighteenth-century French chemist Antoine Lavoisier, a special substance given the name "phlogiston" was presumed to be present in all combustible materials and responsible for their susceptibility to catch fire.

CHAPTER 1: (W)HOLES.

1. Tao Te Ching #11: This "translation" is my own effort to clarify the meaning of this enigmatic entry, based on comparisons between a number of different translations from the original ancient Chinese text.

2. In a famous thought experiment, the brilliant eighteenth-century philosopher-mathematician Pierre-Simon Laplace suggested that to an infinitely knowledgeable mind the world would be an entirely predictable clockwork process, right down to the movement of each atom. He says: "We may regard the present state of the universe as the effect of its past and the cause of its future. An intellect which at a certain moment would know all forces that set nature in motion, and all positions of all items of which nature is composed, if this intellect were also vast enough to submit these data to a.n.a.lysis . . . it would embrace in a single formula the movements of the greatest bodies of the universe and those of the tiniest atom; for such an intellect nothing would be uncertain and the future just like the past would be present before its eyes."-Simon Laplace, A Philosophical Essay on Probabilities (1814/1951), p. 4.

3. The function of an organ was once presumed to be inherited from its divine designer, and thus parasitic in the same sense as artifact function. This view still motivates religious critics of evolution. Since Darwin, this a.n.a.logy has been abandoned in favor of what is often described as a teleonomic view (see chapter 4).

4. The realism/nominalism problem will be faced head-on in chapter 6.

5. A Wikipedia entry (http://en.wikipedia.org/wiki/Little_green_men) suggests that the depiction of aliens as "little green men" may date to an Italian report from as early as 1910, claiming to have captured aliens, and it was also popularized by a newspaper article satirizing Orson Welles' 1938 broadcast of War of the Worlds. It notes that goblins and gremlins have sometimes been depicted as small green humanoids. The linkage to copper-based blood is unclear, but the blue-greenish blood of some arthropods and mollusks has probably been folk knowledge for centuries.

6. Interestingly, the legal system has come down on the side of nominalism when it comes to patentability and owners.h.i.+p of software. In a famous precedent-setting lawsuit, the Apple computer company brought suit against Microsoft for copying the "look and feel" of its object-based Macintosh interface. Apple argued that many features of the Macintosh interface appeared in the Windows operating system and thus violated its copyright. These included icons like file folders, click and drag effects, the use of a mouse, and a trash bin for erasing files. Microsoft won the lawsuit by arguing that although there were indeed obvious similarities of "look and feel," they were created by entirely different software instructions, and thus there was no use of the actual code that Apple had patented.

11. The t.i.tle implicitly parodies Bishop Paley's notion that organisms, like watches, could only have been created by an intelligent designer with a purpose in mind. By describing the watchmaker as unable to see, Dawkins is effectively arguing that there is neither forethought nor purposely guided selection of components and a.s.sembly involved. See Dawkins' The Blind Watchmaker (1996).

12. Except for that one tiny exception, the Big Bang, which created the whole of the visible universe. But that's another story.

5. This theory is often paraphrased by the epigraph "ontogeny recapitulates phylogeny," which means that developmental stages effectively retrace the stages of phylogenetic evolution leading up to the present individual. This was presumed to occur because prior phylogenetic stages represented less elaborated developmental sequences.

5. Gregory Bateson (1979), p. 58.

6. Although Noam Chomsky's article criticizing Skinner's "Verbal Behavior" and a series of learning experiments by John Garcia are often credited with striking major blows, they are probably more like symptoms rather than causes of the abandonment of behaviorism for a more cognitive approach, which was also influenced by people like Jean Piaget and Jerome Bruner.

7. In contemporary digital computers this is accomplished by compiler software, which is usually machine-specific, and mapped to global machine operations.

8. Though it didn't succeed altogether, since as a young man I spent one summer on a rail crew as a "gandy dancer" using a hammer to straighten out spikes bent by a modern version of a motorized spike driver.

14. See Paul Humphreys (1997 a & b). Humphreys would probably object to the much broader a.n.a.logical extension of his concept of fusion that I employ in this comparison. However, the heuristic usefulness of the general idea implicit in his more technical usage is that it exemplifies the system dependence of the concept of a component part.

21. The phrase phase s.p.a.ce originates from the use of graphs to represent the way that substances (like water) change phase from solid to liquid to gas with respect to different values of temperature and pressure. Graphs of other forms of dynamical processes can involve many dimensions, and so may not be easily depicted. The term state s.p.a.ce is in many respects more accurate, since each point in such a graph represents a specific state of the system; however, we can also think of the points along a trajectory of change as being phases of change. In real-world systems, and even complex mathematically represented systems, such trajectories never intersect themselves. But in finite automata this will ultimately occur, at which point the trajectory will form a complex loop following an identical path over and over from that time forward.

22. The phrase is borrowed from the philosopher Daniel Dennett, who used it to characterize an argument that while not demonstrative, nevertheless aids in thinking more clearly about a difficult problem.

24. To continue the a.n.a.logy, fMRI effectively produces a snapshot that is averaged across distances many orders of magnitude larger than neurons, averaged across many seconds or minutes, and often even averaged across multiple trials and multiple subjects.
