It should be sensitive to subject matters and conceptual limitations, but this stands in the way of a natural algebra: even non-distributive or non-modular lattices won\u2019t do.<\/p>\n<p>Besides, a cognitively adequate individuation of content may be intransitive due to \u2018dead parrot\u2019 series: sequences \u03c61, &#8230;, \u03c6n where adjacent \u03c6i,\u03c6j are cognitive synonyms for one while \u03c61 and \u03c6n are not.
