In this talk, I want to present a conception that I have been working on for a number of years (Zwick, 1983, 1995) about the use of systems ideas. I start from the negative and proceed to the positive. The negative assertion is that systems ideas by themselves , unsupplemented by more specific and concrete knowledge (e.g., from the various disciplines), are insufficient for practical application, either for obtaining knowledge about the world or for solving problems. The reason for this (...) is the inherent abstractness of these ideas. The positive assertion is that this metaphysics can be a rich source of insights needed to improve the human condition and a component of a new scientific world view. (shrink)

The aim of this paper is to examine the current state of development of Mäori science curriculum policy, and the roles that various discourses have played in shaping these developments. These discussions provide a background for suggestions about a possible future direction, and the presentation of a new concept for Mäori science education.

Postmodernism was not launched by the development of Warholesque pop art in the 1960s, nor was it initiated by the explosive destruction of the Pruitt-Igoe modern housing project of St Louis, Missouri in 1972, or by the commissioning of Jean-Francois Lyotard's work on knowledge in advanced societies by the Quebec government in the late 1970s. Postmodernism began with the publication of a paper entitled `The individualistic concept of plant the association' in 1926 by the plant ecologist Henry Gleason. If we (...) dare to characterize postmodernism, emphases on ideas such as heterogeneity, ephemerality, anti-foundationalism, pluralism, fragmentation, indeterminacy, schizophrenia, chaos, antiformalism, discontinuity, absence, playfulness, irony, localism, anarchy and ontological meaninglessness are the ones that tend to abound. The Gleasonian theory of plant associations can be said to reflect such ideas in the ecological arena. Certainly there is room for, and an expanding professional commitment to, a fully-fledged neo-Gleasonian postmodern approach to natural history in which ecological phenomena are examined using non-determinist, pluralist and local perspectives that reject the foundationalism and unifying approach of modernist science and which posits a view of the Earth's biota highlighting fragmentation, anarchism and non-interaction. Community ecology, as opposed to the unifying and totalizing tendencies of ecosystems ecology, might rightly claim to be the intellectual site of such a postmodern natural history. Often, postmodern studies not only attempt to describe a postmodern phenomenon but act to forge new varieties of postmodernism. It is in this vein that this paper seeks to present a non-anthropocentric form of postmodernism; not by dissolving the dualistic barrier that separates humanity from nature (as many environmentalisms would advocate) but by dissolving humanity and nature.

The topic of sociobiology and ethics opens up a range of questions that have to do with important relationships: between the history of nature and human being, between biological evolution and psychosocial evolution, between is and ought, between language usages in one domain and another. The task of ethics is properly to discern what sociobiology has to tell us about the fundamentals of life and persuasively to direct our actions in accord with those fundamentals, in a manner that is consistent (...) with our essential humanity. From the theological perspective all of this transpires within the creative will of God. (shrink)

Accounts of the evolutionary past have as much in common with works of narrative history as they do with works of science. Awareness of the narrative character of evolutionary writing leads to the discovery of a host of fascinating and hitherto unrecognized problems in the representation of evolutionary history, problems associated with the writing of narrative. These problems include selective attention, narrative perspective, foregrounding and backgrounding, differential resolution, and the establishment of a canon of important events. The narrative aspects of (...) evolutionary writing, however, which promote linearity and cohesiveness in conventional stories, conflict with the underlying chronicle of evolution, which is not linear, but branched, and which does not cohere, but diverges. The impulse to narrate is so great, however, and is so strongly reinforced by traditional schemes of taxonomic attention, that natural historians have more often abandoned the diverging tree than they have abandoned the narrative mode of representation. If we are to understand the true nature of the evolutionary past then we must adopt tree thinking, and develop new and creative ways, both narrative and non-narrative, of telling the history of life.

Traditional scientific views of the conscious self and world we live in are challenged by an unprecedented outburst of emerging new paradigms, theories of consciousness, perceptions of reality, new sciences, new philosophies, epistemologies, and a host of other transformative approaches. This still expanding outburst can be traced, on both logical and chronologic grounds, not to chaos theory, ecology, the new physics, or dozens of other currently ascribed sources, but rather to the cognitive (consciousness) revolution that immediately preceded. These new approaches (...) all share one key feature in common, namely, they all depend, directly or indirectly, upon a refutation and successful overthrow of the long dominant materialist paradigm. This is what was required to shift consciousness from an acausal or "eliminable" status to a functionally indispensable role. Traditional "bottom‐up" micro‐determinism had to be supplemented by a reciprocal, "top‐down" control exerted by mental emergents over lower‐level components. This does not dispose of behaviorism or reductionism, as methodology, but simply incorporates these within a more comprehensive explanatory framework. With the long reign of materialist constraints finally broken, other antireductive views have proliferated but with little regard for what the new paradigm allows. (shrink)

This essay examines the relation of Darwin's orchids book to a central persuasive flaw in theOrigin: Its inability to give variation sufficient “presence” to break the hold of “design” in the mind of the reader. Darwin characterized the orchids book as “a flank movement on the enemy”; this essay identifies the “enemy” as Paley's natural theology and the “flank” as thetopoi, maxims, and habits of perception that led Darwin's colleagues and contemporaries to see design in nature. Moreover, this essay examines (...) three aspects of rhetorical timing pertinent toOrchids - time askairos, time as adequate duration, and time as transformation - and then relates those features to Robert Cox's Heideggerian logic of repetition, disavowal, and transcendence. The essay concludes with implications of the tactical and temporal aspects of Darwin's reasoning for understanding both the logic of science and of Darwin as a rhetorical artist. (shrink)
