Kenneth Coutts-Smith quotes:

When the symbols are 'public' they usually act in an oblique manner, revealing themselves as archetypal symbols, which though familiar, have their central meanings obscured as is usual in esoteric imagery.

The 'public' artist confirms the world that we already accept, though he inevitably widens our experience of it; his method is one of research, the progressive uncovering of detail.
