1. A mind is an aggregate of interacting parts or components.

2. The interaction between parts of mind is triggered by difference.

3. Mental process requires collateral energy.

4. Mental process requires circular (or more complex) chains of determination.

5. In mental process, the effects of difference are to be regarded as transforms (i.e. coded versions) of events which preceded them.

6. The description and classification of these processes of transformation disclose a hierarchy of logical types immanent in the phenomena.

7. In the mind, the information is unevenly distributed.
