depressants such as alcohol, barbiturates, and benzodiazepines. This circuit appeared first in territorial vertebrate animals and is preserved across all mammals. It corresponds to the mammalian brain of triune brain theory. Wilson equated this circuit with the anal stage in the Freudian theory of psycho-sexual development. The first and second circuits both imprint in a binary fashion: trust/suspicion and dominance/submission. Thus there are four possible ways of imprinting the first two circuits: Trusting 1st circuit and dominant 2nd circuit. I'm OK; you're OK. Friendly strength in the Interpersonal Circumplex. Fire in the four elements model. Choleric in the four humors model. Trusting 1st circuit and submissive 2nd circuit. I'm not OK; you're OK. Friendly weakness. Water in the four elements model. Phlegmatic humor. Suspicious 1st circuit and dominant 2nd circuit. I'm OK; you're not OK. Unfriendly strength. Air in the four elements model. Sanguine humor. Suspicious 1st circuit and submissive 2nd circuit. I'm not OK; you're not OK. Unfriendly weakness. Earth in the four elements model. Melancholic humor. Third Circuit Leary called this the Laryngeal-Manual Symbolic Circuit and Wilson the Semantic Time-Binding Circuit This circuit is imprinted by human symbol systems. It is concerned with language, handling the environment, invention, calculation, prediction, building a mental "map" of the universe and physical dexterity. This circuit is activated by stimulants such as amphetamines, cathinones, cocaine, and caffeine. This circuit supposedly appeared first when hominids started differentiating from the rest of the primates. Wilson, being profoundly influenced by General Semantics, writes of this circuit as the "time-binding circuit". This means that this circuit's contents, including human know-how, technology, science and so on, are preserved memetically and passed on from generation to generation, constantly mutating and increasing in sophistication. Fourth Circuit Leary called this the Socio-Sexual Domestication Circuit and Wilson the Socio-Sexual Circuit. This fourth circuit is imprinted by the first orgasm-mating experiences and local tribal moral standards. It is concerned with sexual pleasure (instead of sexual reproduction), local definitions of "moral" and "immoral", reproduction, rearing of the young, etc. The fourth circuit concerns itself with cultural values and operating within social networks. This circuit is said to have first appeared with the development of tribes. Post-Terrestrial Fifth Circuit This circuit, called the Neurosomatic Circuit, is concerned with neurological-somatic feedbacks, feeling high and blissful, somatic reprogramming, etc. It may be called the rapture circuit. When this circuit is activated, a non-conceptual feeling of well-being
