In the third synthesis, the conjunctive synthesis of consumption, we have seen how the body without organs was in fact an egg, crisscrossed with axes, banded with zones, localized with areas and fields, measured off by gradients, traversed by potentials, marked by thresholds. In this sense, we believe in a biochemistry of schizophrenia (in conjunction with the biochemistry of drugs) that will be progressively more capable of determining the nature of this egg and the distribution of field-gradient-threshold.
