“Knowledge is not a matter of getting reality right, … but rather a matter of acquiring habits of action for coping with reality”
Richard Rorty

Representations
• The action or fact of one item standing for another.
• The substitution of an individual or class in place of another (indexicals)
Representations are labels and sign tokens of membership in a predefined category

Compressions
• Compression is the reduction in size of data in order to save space or transmission time.
• Compressions can be either lossy {some information is permanently lost) or lossless (all information can be restored).
Compressions are stories, models, narratives whichallow the user to ask “what if”

What is the Problem?
Models based on representations are concerned with reliable prediction
Models based on compressions are concerned with attaining better attunement with affordances
These goals are NOT the same
But all too often the models are confused7

The degree of complexity present is the degree to which our chosen
method of reduction has failed
