           | I looked it up, according to Google:
           | 
           | This phrase is a direct quote from the 1955 play (and 1960
           | film) Inherit the Wind, spoken by the character Henry
           | Drummond (based on Clarence Darrow) regarding the teaching of
           | evolution. It frames scientific education and intellectual
           | freedom as the ultimate, pure progress of human civilization,
           | contrasting with dogmatic resistance.
           | 
           | Context: The line refers to the 1925 Scopes "Monkey" Trial,
           | which debated the legality of teaching evolution in Tennessee
           | schools.
           | 
           | Significance: It serves as a dramatic defense of modernism,
           | science, and freedom of thought against traditionalist views.
           | 
           | Cultural Impact: While based on historical events, the play
           | uses this line to argue that intellectual inquiry is the
           | cornerstone of advancement.

         | I think this is a misunderstanding of the arbitrariness of the
         | sign. Arbitrary doesn't mean "random" or "uniformly sampled."
         | The fact there are systematic tendencies among languages in how
         | things are called doesn't negate the arbitrariness of the sign,
         | they _could_ have been called other things. We can also decide
         | to refer to things by another name and we can use any arbitrary
         | name we like! There is no limits on what names we can use
         | (besides silly physiological constraints like having a word
         | with 50 000 consonants). But, of course, there 's much more to
         | language than just labels!
         | 
         | For me, the interesting thing in this paper vis-a-vis language
         | is that it shows how much innate structure in cognition must
         | shape our language.

           | Arbitrariness of the sign is a principle that requires so
           | many epicycles to present as "true" that it's more of a
           | warning against overgeneralization than an insight with any
           | significant predictive power in its own right.

         | No, language is still pretty close to arbitrary labels. The
         | handful of tenuous common threads like the bouba-kiki effect
         | don't change the overall picture that much. The simple fact
         | that language varies as much as it does is sufficient to prove
         | that it's only loosely bound to anything universal.

       | 
       | I'd be interested on results of shapes imagined when you take the
       | source as musical or other non speech sounds.

         | 
         | I think the why just got a lot tricker than we imagined.
         | Because we failed to replicate this experiment on other
         | primates, we couldn't avoid a semantic suspicion about those
         | associations. Now we probably have to set semantics aside or
         | let it get a lot weirder, because we can replicate across
         | ~300My.

         | >surely it's because they represent sharp immediate changes in

         | 
         | Maybe, and I think "multi-sensory signal processing" is the
         | best framing, but the representation could also carry harder to
         | think about things like "harm".
         | 
         | It's also super cool because the bouba-kiki effect framing was
         | chosen due to methodological convenience for linguists and
         | cultural anthropologists and their experimental bounds, not
         | neuroscientists or signal processing folks. We could
         | potentially find other experiments quickly, since chicks are a
         | model organism and the mechanism is clear.
         | 
         | Things could move fast here.

         | 
         | Sure, but it's a very abstract connection between objects being
         | sharp in vision and frequencies changing sharply in hearing.
         | There's no guarantee any given organism would make the
         | connection.
