Gordon Pask Quote

It is clear that an aesthetically potent environment should have the following attributes:

1. It must have sufficient variety to provide the potentially controllable novelty required by a man (however, it not swamp him with variety - if it did, the environment would merely be unintelligible).
2. It must contain forms that a man can interpret or learn to interpret at various levels of abstraction.
3. It must provide cues or tacitly stated instructions to guide the learning and abstractive process.
4. It may, in addition, respond to a man, engage him in conversation and adapt its characteristics to the prevailing mode of discourse.
