  • “…often without knowing what he is going to produce, … uses whatever he finds around him, old cardboards, pieces of strings, fragments of wood or metal, to make some kind of workable object.”

  • What is especially hard for many people to accept is that chance plus selectionpressure can lead from a simple initial condition to highly complex forms and to complex ecological communities comprising such forms. They cannot really bring themselves to believe that such evolution can take place without some kind of guiding hand, some kind of design. [316].

Minimum balloons comprising 90% points from each individual tone type.

The Mandarin tones are relatively compact and discretely distributed, which allows for more successful tone recognition.

约定俗成谓之宜。

名无固实,约之以命,

约定俗成谓之实名。

Model pair-wise interactions between agents:
  • select at random a speaker and a listener
  • select a meaning, mi, that speaker attempts to communicate to listener
  • select an utterance, uj, with which speakerattempts to convey mi
  • select a meaning, mk, that listener infers on hearing utterance uj
  • determine whether the communication was successful (i.e. mi = mk) — if successful, strengthen the mappings between mi and uj— if unsuccessful, weaken the mappings between mi / mk and uj
  • repeat until system converges to some stable state (note that it doesn’t always converge!)

Chao, Yuenren. 1959. Ambiguity in Chinese.

  • Ambiguity is the property of a symbol in being
  • understandable in more than one way. . . .
  • A symbol is vague in so far as its borderland cases
  • of applicability loom large in comparison with its
  • clear cases. …
  • A symbol is general when it is applicable to any
  • one of a number of things whose differences are
  • not denied or necessarily overlooked, but regarded
  • as irrelevant in the context in which the symbol is
  • used.
