\begin{abstract}

  It is proposed to conceive of representation as an emergent
  phenomenon that is supervenient on patterns of activity of coarsely
  tuned and highly redundant feature detectors. The computational
  underpinnings of the outlined theory of representation are (1) the
  properties of collections of overlapping graded receptive fields, as
  in the biological perceptual systems that exhibit hyperacuity-level
  performance, and (2) the sufficiency of a set of proximal distances
  between stimulus representations for the recovery of the
  corresponding distal contrasts between stimuli, as in
  multidimensional scaling. The present preliminary study appears to
  indicate that this concept of representation is computationally
  viable, and is compatible with psychological and neurobiological
  data.
