Spirals, which are close to concentric circles and close to ellipses, can also be “squared” or “oblonged” — pattern recognition is not always neat in its observation of definitions, and this can as easily be a cognitive feature as a bug:
Besides, Plus ça change, plus c’est la même chose could almost be the motto for pattern recognition, emphasizing the naturally cross-disciplinary, cross-silo nature of analogical cognitive strategies.
