Conventional wisdom has had it that the naturalist Alfred Russel Wallace and his colleague Henry Walter Bates journeyed to the Amazon in 1848 with two intentions in mind: to collect natural history specimens, and to consider evidential materials that might reveal the causal basis of organic evolution. This understanding has been questioned recently by the historian John van Wyhe, who points out that with regard to the second matter, at least, there appears to be no evidence of a “smoking gun” (...) variety proving it so. In the present essay the circumstances of Wallace’s interest in the matter are reviewed, and van Wyhe is taken to task with alternate explanations for the facts he introduces in his argument. The conclusion is that Wallace almost certainly did have the second objective in mind when he left for both the Amazon, and the Far East. Keywords: Alfred Russel Wallace, Henry Walter Bates, evolution, natural selection. (shrink)

Physicist David Bohm and biochemist Ilya Prigogine began a dialogue that implied a deep, structuring, primordial harmony within life. In classical Chinese this harmony is referred to as Li, which also designates the elegant, natural pattern found in jade. This article emphasizes the ways that perception of primordial harmony gives way to a vision of possibility and to the creative intelligence and action necessary for meeting the challenges we face. Insights from Bohm, Prigogine, and others on releasing outmoded thinking and (...) actions are integrated with contemplative traditions, Eastern and Western philosophy, and pragmatic strategy making.

Geography has traditionally been assigned the role of handmaiden in evolutionary studies. In this work a different understanding of the relationship between biological change and locational setting is developed: evolution as a dynamic form of spatial interaction. In the causal model presented, adaptive change is portrayed as a negative feedback response contributing to a general spatial-temporal process of resource cycle tightening involving exchanges between the two fundamental structural sectors (abiotic and biotic) of the earth's surface system. As such, it is (...) rejected as evolution per se. This position makes it possible to circumvent the adaptation yields adaptation circularity, and to view locational circumstances as being evolutionarily causal, yet not deterministic with respect to population-level change. A parallel interpretation of the relation between range and range change and evolution is also implicit; the individualistic hypothesis is thereby superceded by a model of community evolution allowing for individualistic rates of population (adaptive and) range change, but operating on the principle that populations should tend to change range in common directions (as a response to spatially-varying degrees of efficiency of turnover of resources vital to biotic sector function). This in turn leads to the possibility of normative biogeographic modelling. Comment is also made on the relationship of the present understanding to disequilibrium and dynamic equilibrium interpretations of evolutionary change, and to human cultural evolution. (shrink)

This article suggests that ?evolutionary vision,? the unifying paradigm of physical, biological, and sociocultural evolution, needs to be fully embodied and deeply experienced in the human being, and that this can be effected by the experience at the heart of the ?perennial wisdom tradition,? 1 that is, that of ?non-dual perception.? The article suggests an ?action-based? experiment paralleling the method of a ?thought experiment,? based on the assumption that one way that one can experience this embodiment is by ?trying on? (...) the lens of non-dual perception, as practiced by the many traditions of perennial wisdom. (shrink)
