Prometheus R&D argued and defended the opinion that synesthesia rather than being a mind anomaly is a norm of human psychic perception, imagination, and creativity manifested in non-verbal thinking, realized by either involuntary or by purposeful comparison of different modalities, on the basis of structural, semantic, or emotional similarities. In this context, synesthesia associates with cultural aspects rather than being a biological phenomenon, moreover, Bulat Galeyev persistently stressed that language, monosensory, and bisensory arts, serve as the “testing areas” where synaesthesia is formed and most actively cultivated.
