nacademics
This is the third video of this series (NACADEMICS, adventure into the realm of concepts). In this video the concepts with the sounds (given in video 2) are argued to match the categorization done by American philosopher Charles Sanders Pierce.
The sounds formed since the great encounter with harsh climate change around 90000 years ago can be considered as iconic class of signs, that is, they are direct but sonic imitation of the realities of the concepts.
This iconic class of sounds has developed as indexes into morphemes and the as symbols into words.
