My "tabula rasa" context defines the most general concepts which are used to express all knowledge. Such concepts are called "axiomatic" concepts. For efficiency, I have also included some non-axiomatic concepts in tabula rasa. Here is a hierarchy outline (a taxonomy) of the most important concepts in tabula rasa. existent entity animal person plant object characteristic attribute purpose space time view part action relation proposition This structure is defined by a set of KR species-genus propositions, which are part of the "first" set of propositions in a "diary" context. (For now, I am ignoring the "differentia" which distinguish the species of a genus.) (1) entity, characteristic, proposition iss existent (2) animal, plant, object iss entity (3) person iss animal (4) attribute, part, action, relation iss characteristic (5) purpose, space, time, view iss attribute Further KR propositions can be expressed using these concepts, e.g. (6) Jane isu person (7) Jane has sex=female From (6),(7) KR/KE automatically infers that (8) Jane has ctype=unit (9) sex iss attribute (10) female isu sex Specifying the full meaning of a concept -- all the facts of reality it denotes -- all the extensions and intensions may require a large number of KR propositions. We can reduce that number by using genus-differentia definitions. But for some concepts we won't be able to capture the full meaning -- the "diary" context will be "less than" the "full human" context . Depending on our purpose, we may or may not care. ============ Dick McCullough knowledge := man do identify od existent done knowledge haspart proposition list
