More on the Relations among Categorization, Merge and Labeling, and Their Nature

Concerning (i), I will claim that the two apparently distinct modes of operation of categorization stem from differences of ‘extraction patterns’ and thus as a precursor of Merge the particular mode of categorization such as IntCat should not be stipulated. As for (ii), I will make clear the relation between the low-order categorization involving a series of entities and the higher-order categorization involving a series of category sets in humans and non-human animals, in connection with the qualitative difference of the two types of categorization between them in the context of the evolution of human language.
