synchrony hypothesis (Peter Milner 1974; Crick & Koch 1990). For example, Wolf Singer<br />

(1996, 2007) contends that binding the distributed representations of an object’s properties is<br />

achieved by “the synchronization of neuronal responses with high temporal precision” (2007,<br />

p. 608). Singer also alleges that conscious experience depends upon the binding activities that<br />

underlie the formation of a unified meta-representation: “If conscious experience depends on<br />

the ability to dynamically bind the results of subsystem computations into a unified metarepresentation,<br />

conditions required for the formation of meta-representations ought to be the<br />

same as those required for awareness to occur” (Singer, 2007, p. 607). A philosophical upshot<br />

is that binding is necessary for conscious experience, since without binding there could be no<br />

unified meta-representation. Luck and Beach argue in favor of a neural suppression account<br />

of binding: binding is “achieved by simply suppressing information arising from unattended<br />

locations”, thereby allowing the neurons that remain active to “reflect features of a single<br />

object” (1998, p. 461). Neural suppression operates to filter out unattended information so<br />

that the neurons which remain active can render explicit the representational properties of an<br />

object. I elaborate and provide a critique of Singer’s view, and then examine Luck and Beach’s<br />

neural suppression account. I argue (1) that neuronal synchrony is not sufficient for binding<br />

the distributed representations of an object’s properties into a unified object of consciousness;<br />

(2) that binding is not necessary for conscious experience; and (3) that although synchrony<br />

and suppression might play the role of tagging the distributed representations of an object’s<br />

properties when competition arises within the cortical neural network, this does not explain<br />

the more difficult question about the unity of consciousness. C17<br />

140 No Syncrony Below N+1: The Sum of the (Parent and Daughter Particles<br />

As) Members of a Self-Inclusive Set Francis Schwanauer <br />

(Philosophy, University of Southern Maine, Portland, ME)<br />

Aristotle’s predicate logic, which classified any ‘1’ substance with its simultaneous ‘n’<br />

characteristics an early symbolic version of our practical present day accelerators or atom<br />

smashers of ‘1’ parent particle into its ‘n’ synchronous daughter particles – was eventually<br />

elaborated upon by set theory, which allowed for a fitting inclusion of the ‘1’ among the ‘n’,<br />

for the ‘n+1’ members of a self-inclusive set, by such as Russell. This self-inclusion by way<br />

of ‘n+1’ was paralleled in physics by subsuming the synchronously moving ‘n’, such as the<br />

two ends of the lever (cp. Archimedes), or ‘action and reaction’ (cp. Newton), under the ‘1’<br />

transformation and/or chain reaction a la E=mc2 (cp. Einstein). With the given synchrony of<br />

the ‘n+1’ as a spatial relation still short of its plausibility as a temporal relation, however, science<br />

was forced into a non-linear dynamical face-lift of our linear dynamical image of causality<br />

by means of a selective representational apparatus (RA), to cope with the more complex<br />

transformational wake of ‘n+1’. This historical, useful, and apparently harmless improvement<br />

on the merely ‘mechanical’ and no longer adequate classical approach with a ‘conscious and<br />

decisive’, RA, as culminating in the postulate of some ‘free’ agent in super-positional charge<br />

of natura naturans, however, not only smacked of a metaphysical admixture to research and<br />

methodology, but also split the world of serious science into two opposing camps at a ratio of<br />

roughly 88/12 between proponents of upward and downward causation, respectively. Nevertheless,<br />

this split among otherwise likeminded colleagues is fortunately premature and largely<br />

unwarranted, since neither of the opposing camps has as yet demonstrated to the other, how<br />

one and the same RA can or cannot be two such absolutely divergent items as 1: ‘a symbol’<br />

of a myriad of representational possibilities to choose from, and also 2: a ‘concisely comparing<br />

or even whimsically preferring judge’ deliberately choosing among them. Yet a more<br />

intensive study of synchrony in self-organization - such as the human body - shows that the<br />

RA cannot be both a representational possibility and its comparing judge at one and the same<br />

time, since (demonstrable) synchrony as confined to such as attraction and repulsion, action<br />

and reaction, the two ends of the lever, etc., is not an internal or local property but an external<br />

non-local condition of any ‘n’, and thus is not deducible from the synchronously moving ‘n’,<br />

but their simultaneously transforming ‘1’ in ‘n+1’ as a self-inclusive set. As I try to show in<br />

my paper, synchrony among the local emanates from the non-local, as is evidenced by its local<br />

tracks in any RA and the observation of the shadows of the Higgs boson in Cern. P8
