The suggestive use of metaphors -- like the "universe of knowledge", academic "stars", "luminaries" and "stellar" careers, "heated" debate, high "visibility", "massive" support, "weighty" argument -- points to the possible value of exploring whether astrophysics offers a coherent set of metaphors to explore various kinds of psychosocial life cycle.
Use is widely made of "brilliance", whether or not associated with "stellar" or "star" in some way. The implications are typically relatively simple -- as with recognition of celebrities with the phrase "a star is born", or with much admiration of the stars at night. The question here is whether the insights elaborated by astrophysics regarding the nature and life cycle of stars offer means of enriching their use as a metaphor. Cause for deeper reflection is the widely-cited quotation of astrophysicist Carl Sagan:
The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of starstuff.
As discussed separately (Generative metaphor and policy-making, 1995), in a key paper, Donald Schon (1979) argues that:
... the essential difficulties in social policy have more to do with problem setting than with problem solving, more to do with ways in which we frame the purposes to be achieved than with the selection of optimal means for achieving them." For Schön "the framing of problems often depends upon metaphors underlying the stories which generate problem setting and set the direction of problem solving. (Generative Metaphor: a perspective on problem-setting in social policy. In: A. Ortony (Ed.), Metaphor and Thought, 1979, pp. 254-284)
A "generative metaphor" offers figurative descriptions of social situations, usually implicit and even semi-conscious but that shape the way problems are tackled, for example seeing a troubled inner-city neighborhood as urban "blight" and, hence, taking steps rooted in the idea of disease. The approach has been developed by Frank J. Barrett and David L. Cooperrider (Generative Metaphor Intervention: a new approach for working with systems divided by conflict and caught in defensive perception, Appreciative Inquiry Commons, 2001).
A valuable summary of relevance to the following argument is offered by Jozef Keulartz (Using Metaphors in Restoring Nature, Nature and Culture, 2, 2007) of the European Network of Environmental Ethics:
Metaphors perform important cognitive functions, operating as mechanisms for the translation of something abstract into something concrete and shedding light on new and unknown phenomena through familiar ones. In short, metaphors are heuristic devices crucial for creating and conceptualizing novel ideas and new knowledge. However, metaphors are not only important cognitive tools in making sense of the world but also important discursive tools that enable communication and negotiation with others throughout the world. Metaphors then are also diplomatic devices that facilitate interaction between different disciplines and discourses (Hellsten 2002)....
Once it is acknowledged that the use of metaphor is inescapable and indispensable, however, we are confronted with the problem of the sheer multiplicity of metaphors. With respect to nature, Daniel J. Philippon (2004) has provided us with an extensive, although not exhaustive, list of metaphors for nature. Nature can be compared to a particular place (frontier, garden, park, wilderness, utopia), to a friend or family member (self, mother, father, sister, brother, wife, husband, partner), an actor (god or goddess, minister, monarch, lawyer, selective breeder, enemy), a network (web, community, tapestry), a machine (clock, engine, computer, spaceship), a state of being (virgin, harmony, balance), a mode of communication (book), a built object (bank, sink,storehouse, pharmacy, lifeboat, home), or to a contested landscape (battlefield, commons) (Philippon, 2004; see Harré et al., 1999)....
Taken together, the cognitive, discursive, and normative functions of metaphors determine our attitude towards entities in the world. Thus, for example, people who see nature as a divine text will be more likely to adopt a passive rather than an active attitude towards nature, while those who look at nature as a machine might stress our possibilities to control, command, and correct nature.
The approach taken here is first to note some distinct domains in which "brilliance" is recognized. Some have been explored in other documents on this site, as noted below (whose arguments have been partially reassembled here for convenience). The argument then introduces the Hertzsprung-Russell diagram. This is a basic mapping of the life cycle of stars, including their eventual demise. Commentary is then provided below on some details of this "map", and the variety of stars -- represented at different stage there during the course of stellar evolution.
The commentary itself is only presented in terms of the life cycle of communities as but one of the domains in which "brilliance" may be recognized and appreciated. The metaphor is explored there in italicized text to accompany the conventional description of the astrophysical case. With respect to other domains, that italicized description then needs to be interpreted in terms of the nature of those domains -- as suggested by the preceding references to them.
Reference to the metaphor stellar evolution and the Hertzsprung-Russell diagram has been made in the following distinct contexts which each refer to the more articulated description which follows below:
Evolution of gated conceptual communities in the light of stellar evolution (as discussed in Dynamically Gated Conceptual Communities: emergent patterns of isolation within knowledge society, 2004):
The appropriateness of the metaphor derives from what might be termed the physics of communication amongst the "stars" of the knowledge firmament -- and the limited number of parameters by which this could be modelled: interactivity of participants (temperature?), visibility (luminosity?), membership/connectivity (mass?), insight/inspiration/curiosity (hydrogen?), weight of facts/tradition/confirmation (gravity?).
Use of the metaphor is discussed more extensively below as a template through which the following alternative uses may be explored.
Point-making and identity in the light of stellar evolution (as discussed in Going Nowhere through Not-knowing Where to Go: sustaining the process of autopoiesis through point-making, 2013):
Why are "light" and "brilliance" such acceptable metaphors in communication processes and the appreciation of insight? Why are celebrities in many domains termed "stars"? Why the preoccupation with "visibility" in the promotion of people and initiatives? Why the value and meaning attached to "enlightenment"? Why the ambiguity and concern relating to the "dark" (Enlightening Endarkenment: selected web resources on the challenge to comprehension, 2005).
Conscious life in the light of stellar evolution (as discussed in Towards an Astrophysics of the Knowledge Universe: from astronautics to noonautics? 2006):
How does the array of relatively simple reactions sustain the complexity and coherence of a sun? Can consciousness be understood in terms of the patterns of solar reactions through which light and heat are generated for mundane life -- in the light of Cybernetics and Human Knowing (A Journal of Second Order Cybernetics, Autopoiesis and Cyber-Semiotics) ? What then is to be understood by hydrogen and helium?
In the further course of evolution, the star may become unstable, possibly ejecting some of its mass and becoming an exploding nova or supernova or a pulsating variable star. The end phase of a star depends on its mass. A low-mass star may become a white dwarf; an intermediate-mass star may become a neutron star; and a high-mass star may undergo complete gravitational collapse and become a black hole. Are some of these patterns not reminiscent of the possible final stages of life of media personalities -- especially movie "stars", but also the geniuses of our era?
Conceptual evolution in the "space-time" of knowledge space (as discussed in Present Moment Research: exploration of nowness, 2001):
Consideration could be given to combining the processes implicit in metaphors explored above into what amounts to an understanding of conceptual evolution in the "space-time" of knowledge space? This might be mapped by some equivalent to the astrophysicists Hertzsprung-Russell diagram -- which indicates the evolutionary pathway of stars in terms of changing mass and luminosity. What is required is a sense of the evolution of conceptual attractors in knowledge space in terms of the attraction they exert and their visibility. With respect to fascination with the origin of the physical universe, it is especially intriguing in this context to consider how analogues to its first "3 seconds" may be a characteristic of the subjective sense of the present moment.
From this perspective there are cognitive processes in the first fractions of a second of attention that continually form the universe that is then open to subsequent experience as fully made. How does "the future" relate to the space-time of cognitive space? The seemingly esoteric debates about whether the universe started with a Big Bang may be explored for their systemic significance as patterns to moment-by-moment creativity, as well as to cell division. The process of concept formation at the moment of creativity, or of cell division after conception, have structural similarities to insights into universe formation.
There may be a way in which the coherence of the moment may be experienced as a kind of standing wave phenomenon. Analogues to the formation of "heavy atoms" may be detected as the creative process meshes with reality -- suggesting a kind of periodic table of creative insight. This would help to explain the ability of traditional cultures to generate cosmologies through which their reality is structured. In particular it clarifies the perspective from which, as noted by Diana James, Australian Aboriginal cultures are able to live in a continuous present that is intimately associated with a mythical Dreamtime.
Focus on the brightest "stars" and stellar evolution (as discussed in Openness and Closure in Pattern Language: Geometry versus Resonance, 2012):
In contrast with insights mined from the preoccupations of fundamental physics (with the very small and short-lived), there is an irony in this respect to the significance of those borrowed from the very large and long-lived, namely from astrophysics (Towards an Astrophysics of the Knowledge Universe? from astronautics to noonautics, 2006).
Whether in strategic gatherings, or in gatherings of physicists, "stars" are a focus of attention -- especially the "brightest". Some topics could be said to be avoided like "black holes" or "dark matter". The "gravity" of their pronouncements may be felt -- recalling the origin of the term in gravitas. As noted above, the temperature of discourse may be significant -- especially in "heated" exchanges. It is of course the case that "stars" may be recognized as exploding upon the scene like supernova, whilst the visibility of others may diminish over time, perhaps imploding and becoming spent -- as with any "model", beauteous and elegant, or otherwise.
Efforts to formulate a Theory of Everything -- through such gatherings -- would treat any psychosocial processes as totally irrelevant, despite their role in the recognition of Nobel laureates. Astrophysics frames the physical processes in terms of the Hertzsprung-Russell diagram. -- a major step towards an understanding of stellar evolution or "the lives of stars". A corresponding insight is offered into the "careers" of concepts, within the strategic universe of the United Nations, by Johan Galtung (Processes in the UN system, 1980), as quoted separately with respect to Meaningful opportunities and the movement of meaning (1988):
If such a strategic concept is understood to be a "point" in knowledge space, mixing metaphors in the light of Galtung's comment, it might be asked whether attention should be given to the "half-life" of any strategic point -- especially those recognized as "hot topics". The question also relates to the extensive research on anomalies by Charles Fort, widely quoted to the effect that: I conceive of nothing, in religion, science or philosophy, that is more than the proper thing to wear, for a while.
A good point of departure is the famed Hertzsprung-Russell Diagram, pioneered independently by Elnar Hertzsprung (1911) and Henry Norris Russell (1913). It is recognized as one of the greatest observational syntheses in astronomy and astrophysics. The diagram plots the luminosity of stars as a function of their temperature. The luminosity, or absolute magnitude, increases upwards on the vertical axis; the temperature (or some temperature-dependent characteristic such as spectral class or color) decreases to the right on the horizontal axis. From this it is readily apparent that stars preferentially fall into certain regions of the diagram along a curving diagonal line called the "main sequence", although there are other regions where other types of stars (red giants, supergiants, white dwarfs, super novae, pulsars, flare stars) also fall [more].
The suggestion is that conceptually gated communities (and various kinds of social group) emerge and live out their lives in a way that could be represented on an analogous diagram. In public relations terms, there is already a familiarity with the visibility of a group (its "luminosity") and a sense of whether it is "hot" or "cool". The analogue to temperature may be more meaningfully understood as degree of communication interactivity amongst members of the community -- especially since temperature is associated with interactivity between atoms. Following from work of B W Tuckman (Developmental Sequence in Small Groups, 1963) the stages of Forming / Storming / Norming / Performing (see also R B Lacoursiere. The Life Cycle of Groups: Group Developmental Stage Theory, 1980; Stan Davis, The Life Cycle of Organizations, 1990). A sense of the knowledge exchange processes is usefully explored by Martha G. Russell and Kaisa Still (Engines Driving Knowledge-based Technology Transfer in Business Incubators and Their Companies, 1999).
In the case of religious groups, the life cycle has for example been characterized by David Moberg (The Church as Social Institution, 1984) in phases:
Seemingly analogous to the H-R diagram, Lawrence Cada et al. (Shaping the Coming Age of Religious Life, 1979), identified a "vitality curve" in the light of a historical study of the life cycle of religious institutions. As discussed by Mary V. Maher (Between Imagination and Doubt: Religious Life in Postmodern Culture, 2003), Cada distinguishes five separate stages of a religious movement's history:
As noted by Tim Thompson: "A star is not a static thing, it changes with time. The process of aging in stars is called stellar evolution. As a star ages, it goes through changes reminiscent of the life cycles of living things, the details of which depend on the star's overall mass. Massive stars live short but exciting lives, whereas small stars live long, quiescent lives." [more]
The H-R diagram is considered to be a useful way to follow the changes that take place as a star evolves [more]. Its regularity is an indication that definite laws govern stellar structure and stellar evolution. Building mathematical models of stars, based on straight forward physics, and allowing those models to evolve naturally in time as a star ages, recreates the H-R diagram as it is observed -- with a surprising degree of fidelity of agreement between theory and observation that is of great interest in astrophysics. The ability of the theory of stellar evolution to explain the H-R diagram in its finest details, singles out stellar evolution as one of the most successful and productive of scientific theories. Most stars lie on the main sequence, burning hydrogen to helium through nuclear reactions. As they live out their lives, changes in the structure of the star are reflected in changes in stars' temperatures, sizes and luminosities -- causing them to move in tracks across the diagram.
Is there a case for recognizing that the life of community is determined by the rate at which its initial unifying and energizing inspiration (with a propensity to enter successfully into explanatory bonds) is converted into a polarized and essentially neutral or sterile perspective? Are such possibilities suggested by explorations such as that of Ilanit Tof (Modern Cosmology as Psychological Metaphor, 1996)?
Stellar evolution is not studied by observing the life cycle of a single star; rather, by observing numerous stars, each at a different point in its life cycle, and running computer models that simulate stellar structure. Following the Wikipedia description of such evolution, phases to be distinguished are:
Giant molecular interstellar cloud: This initial stage is distinguished by its very low density and large size. It might usefully be equated to some movements of opinion in their very first phases. The cloud is stable, its constituent molecules being too widely spaced for gravity to draw them closer
Protostar: The next stage results when the cloud is destabilized, such as by a supernova sending out a shockwave of successive compression and rarefaction (analogous to a soundwave travelling through air), knots of matter are formed -- cores of greater density. Diffuse movements of opinion may similarly be stimulated to coalesce -- such as by shocks like 9/11. When the density exceeds a certain threshold, gravity takes over, and the region begins to collapse into a protostar (each dense core producing anywhere from 1 protostar to tens of thousands). As exchanges increase, between those attracted to the particular perspective, the force of attraction increases -- a centre of gravity effectively becomes defined. The atoms gain speed in their fall toward the center, providing the protostar with heat (heat is defined as particle motion), a weak infrared glow, and rotation. The movement transforms into a loose organization, exchanges may become heated, the community becomes faintly visible, and its members may be understood as acquiring orientation. The lowest mass stars are classified as red dwarf stars, but even red dwarfs are massive enough to trigger hydrogen fusion in their cores to sustain their feeble starlight. If the collapse of the fragmenting interstellar cloud results in an object of less than about 0.08 solar masses, the central temperature and density of the protostar will never get high enough that hydrogen fusion can take place in a sustained, controlled manner. Such an object is a brown dwarf. These can shine only briefly as their central temperatures are too low to utilize hydrogen as nuclear fuel. Contraction remains the only source of energy; they die away slowly, over hundreds of billions of years. As it collapses, the brown dwarf will shine because it converts its gravitational energy through contraction into luminosity -- being heated by gravitational contraction up to 15 million degrees Kelvin, stripping the electrons from their parent atoms, creating a plasma.
Maturity: A new star emerges at a specific point on the main sequence of the H-R diagram. New stars come in a variety of sizes and colors. Stars range from blue to red, from less than half the size of our Sun to over 20 times its size. The brightness and color of a star depend on its surface temperature, which depends on its mass. According to its nature and size, a conceptually gated community may also be understood as emerging at a specific point in a "main sequence". The community may even be distinguished by "colour": blue, red, green, brown, black (as explored in the UNU GPID project). The star will rest there for a period of years: millions (for the biggest and hottest stars); billions (for mid-sized stars like the Sun); tens or hundreds of billions (for red dwarfs). During this time it expends most of the hydrogen in its core. Eventually the supply of hydrogen runs out and the star enters a new phase of its life. The community may remain in the "main sequence" for an extensive period of time, until its supply of "inspiration" and "vision" runs out and it enters a new phase of existence. During this period of maturity the star's existence is a tug of war between gravity, which wants to crush the star into a point, and the fusion going on inside, which wants to explode the star and send pieces of it hurtling through the universe. For the community, this period of existence is a tug of war between the force pulling the community into a one-pointed "integral" or "unified" perspective (most evident in the case of fundamentalism) and the tendency to explode throughout society (again most evident in the missionary impulse of religious and ideological groups).
Beginning of the end: Once the supply of hydrogen in the star's core is depleted, nuclear processes there cease. A conceptually gated community is also faced with the prospect of cessation of the core processes sustained by its inspiration. Without the outward pressure generated by these reactions to counteract the force of gravity, the outer layers of the star begin to collapse inward, toward the core. The community then tends to collapse in upon itself -- it becomes increasingly inward looking. The temperature and pressure increase as during formation, but now to even higher levels, until helium fusion begins. During the process of collapse of a community the dynamics become increasingly heated -- associated with furious increase in self-righteousness, self-justification and pressures to conform. The newly generated heat temporarily counteracts the force of gravity, and the outer layers of the star are now pushed outward; the star becomes as much as 100 times larger than it ever was during its maturity. It is now a red giant. The mass has not increased, so its density is much lower (except in the inner core, where the density is higher than during the hydrogen fusion phase). In the case of a community, this might be understood as a final missionary phase through which adherents are widely dispersed outward from its headquarters.
End of stellar lifecycle: The final phases of stellar evolution depend on the star's mass. Similarly the final phases of evolution of a conceptually gated community depend on the extent to which it is mass movement. Is there a degree of equivalence to be found with the pattern of social collapse identified by Jared Diamond. (Collapse: How Societies Choose to Fail or Succeed, 2004)?
