and Peat, 1987), examples of implicate orders in science are laid out, as well as implicate orders which relate to painting, poetry and music. Bohm and Peat emphasize the role of orders of varying complexity, which influence the perception of a work of art as a whole. They note that implicate orders are accessible to human experience. They refer, for instance, to earlier notes which reverberate when listening to music, or various resonances of words and images which are perceived when reading or hearing poetry. Christopher Alexander discussed his work in person with Bohm, and pointed out connections among his work and Bohm's notion of an implicate order in The Nature of Order. Bohm features as a fictional character in the novel The Wave by British author Lochlan Bloom. The novel includes multiple narratives and explores many of the concepts of Bohm's work on implicate and explicate orders. Challenges to some generally prevailing views In proposing this new notion of order, Bohm explicitly challenged a number of tenets that he believed are fundamental to much scientific work: that phenomena are reducible to fundamental particles and laws describing the behaviour of particles, or more generally to any static (i.e., unchanging) entities, whether separate events in spacetime, quantum states, or static entities of some other nature; related to (1), that human knowledge is most fundamentally concerned with mathematical prediction of statistical aggregates of particles; that an analysis or description of any aspect of reality (e.g., quantum theory, the speed of light) can be unlimited in its domain of relevance; that the Cartesian coordinate system, or its extension to a curvilinear system, is the deepest conception of underlying order as a basis for analysis and description of the world; that there is ultimately a sustainable distinction between reality and thought, and that there is a corresponding distinction between the observer and observed in an experiment or any other situation (other than a distinction between relatively separate entities valid in the sense of explicate order); and that it is, in principle, possible to formulate a final notion concerning the nature of reality, i.e., a Theory of Everything. Bohm's proposals have at times been dismissed largely on the basis of such tenets. His paradigm is generally opposed to reductionism, and some view it as a form of ontological holism. On this, Bohm noted of prevailing views among physicists that "the world is assumed to be
