In this first experiment, we have a convincing demonstration that communication of a semiotic (iconic) nature (analogous to radio broadcasting in the electromagnetic field) may be supported by an immaterial field such as the morphic fields of Rupert Sheldrake, We do not claim to establish the existence of such fields, nor the capacity of the brain to emit or receive them. However, the whole language and cognitive strategy of Sheldrake, involving morphic fields and morphic resonance as the basis for physical, biological, and social morphogenesis, is strongly supported by our results.
