ABSTRACT
During my tenure in professional life, I had found four aspects of knowledge (items & relationships, quantitative & qualitative values, spatiality, change; see Basden (2008, Chapter VII)); but what was the ‘full set’? It would need philosophy to answer that. So upon returning to academic life in 1987, I approached a professorial colleague who knew some philosophy and innocently asked her what the full set was. She replied, “There aren’t any. Your aspects are socially constructed.”
