The diagrams ( a.k.a. pictures, illustrations or graphics) that I drew have been a critical factor in the success of this project.

Rather than being mere illustrations used for ancillary purposes, they are essential mnemonic devices which both summarise and document the sequence of key mental concepts that were required to complete the reverse-engineering (adducive, or Pierceian reasoning) processes that drove the project's problem solving paradigm to its unanticipated level of (quantitative, predictive) success and satisfactory level of (qualitative, explanatory) exposition.

The process of model discovery (deconstruction) is depicted by the diagrams of part 1, 'From notion to neuron'. The idea is this- in the first one-third of the project, the analysis proceeded functionally from the outside (the mind produces 'notions') to the inside (the brain utilises 'neurons').

The process of model construction is illustrated by the graphics of part 2, 'From neuron to notion'. In the second one-third of the project, the analysis proceeded functionally from the inside to the outside. The TDE is used as a computational canon, a bit like the Turing Machine, as a generic design template.

The process of model integration is summarised by the graphics of part 3, 'From Computation to Cognition. In the final one-third of the project, the analysis proceeds from the parts to the whole. CTM is used as the theoretical basis for a new internally consistent and externally validated view of human cognition,  integrated its previously disparate facets- cognitive philosophy, science and engineering.

The process of model application  is illustrated by the symbologies and schematics of part 4. The section consists of a graphical exploration of the wider possibilities, such as unification of key metadigms in biological computation, further development of post-behaviourist theory, and achieving the Chomskyist 'dreme' of the ULM or universal language machine.
