Improvement in reasoning requires, first of all, a study of deduction. For this, an unambiguous and simple system of expression is needed. The system in which reasoning is broken up into its smallest fragments by means of diagrams is the system of existential graphs, which CSP goes on to develop in terms of fourteen conventions.
