Stained-Glass Thinking is the cognitive method used in the development of Relational Field Theory (RFT).
It is a structured process for building mathematical frameworks from relational and geometric intuition, rather than starting directly with equations.
This method makes explicit the sequence through which structure, meaning, and formal representation emerge.
The method begins by perceiving a system as an interconnected structural pattern, then translating that structure into physical meaning, and finally expressing it mathematically.
This ensures that formal equations remain grounded in underlying structure rather than isolated symbolic manipulation.

All reasoning proceeds through five ordered layers:
The system is perceived as a dynamic, interconnected pattern of relationships.
This layer is purely structural—no equations or formal language are introduced.
