Among the many and diverse treatments of the concept of “field” scattered through a wide range of literature is to be found a marked and growing tendency to interpret the “field” as a psychic phenomenon, notably as witnessed in the various attempts which have been made to explain associative groups of elements as field phenomena. Such an approach, however, is by no means always justified, if for no other reason than the fact that various associative groups are by their nature non-identical. Such non-identity is in particular to be explained by the existence of various types of associations, so that unifications of elements may, for example, have both a paradigmatic and a syntagmatic nature.
