Before i delve further into the misconferral of authority by antifluoridationists, an i’d like to make point about scientific consensus that i neglected in my previous post. It is easy to think of scientific knowledge as essentially static, with the occasional fact or theory being overturned when new evidence surfaces. We imagine scientific knowledge as a sort of pyramid, with the most reliable knowledge composing the base and provisionality increasing as we move upward. While this model is useful for making the quintessentially (Humean–)Bayesian–Pricean point that stronger evidence should more strongly inform our beliefs, it falls apart as soon as we widen our scope from the single
Providence province to which the pyramid aspires. The sciences are not independent avenues of discovery, as imagery of a field of pyramids might suggest, but highly interdependent configurations of highly intradependent evidences and interpretations.
To draw an analogy of my own: The highly symbolic and culturally entangled concept of gender is not reducible to the space determined by orthogonal (and necessarily binary) spectra of identity, expression, “biological” sex, and attraction; it involves the highly nontrivial and individualized interplay of these factors, each of which in turn arises from the interplay of several distinguishable (if not wholly distinct) factors. A perhaps preferable model of gender is the graph representation of these interrelations: a node for each factor and edges tying them together, with the understanding that any particular node (say, “attraction”) may dissolve into a subnetwork of factors (intimacy, arousal, sexuality, satisfaction, saturation, etc.) on closer scrutiny.
Similarly, out of the intricate network of implications, corroborations, constraints, and tensions that connect elements of our aggregate body of facts and interpretations arises a web of knowledge. Moreover, this web may be anywhere localized, as though sliding a magnifying lens over a paper map, so that all our knowledge may be interpreted in terms of its relevance, or “consequential proximity”, to one’s topic of choice. Ultimately no particular discipline or theory is more “central” than any other.
