37. The idea of a category is central... Most symbols (i.e., words & representations) do not designate particular things or individuals in the world... Most of our words & concepts designate categories. There is nothing more basic than categorization to our though, perception, action & speech. Every time we see something as a kind of thing [...] we are categorizing Lakoff, ”Women, Fire and dangerous things”

40. [Classical category theory] is built into the foundations of mathematics and into much of our current computer software. Since mathematical and computer models are being used more and more as intellectual tools in the cognitive sciences, it is not surprising that there is considerable pressure to keep the traditional theory of classification at all costs. It fits the available intellectual tools, and abandoning it would require the development of new intellectual tools. And retooling is no more popular in the academy than in industry. Lakoff, ”Women, Fire and dangerous things”

43. Categories are not merely organized in a hierarchy from the most general to the most specific, but are also organised so that the categories that are most cognitively basic are "in the middle" of a general-to-specific hierarchy. Generalisation proceeds upward from the basic level and specialization proceeds down
