There are four functions (T, N, S, F)
Two are deemed "rational" (T/F) and two are deemed "irrational" (N/S).
The irrational functions are known as perceiving and the rational functions are known as judging.
Consciousness is defined by the interplay of a function pair, consisting of one rational and one irrational function (one P and one J).
Functions are identified by the existence of types. A "type" is a pattern of objective behavior and subjective experience that characteristically represents one function, which shall be known as dominant.
Types are either rational or irrational.
A dominant function represses the other three functions into [some degree of] unconsciousness. This can be mathematically represented by a partial differential equation.
A conscious function represses the other function in its own category (P/J) more strongly than the functions in the orthogonal plane (P _|_ J).
Attitudes are two distinct and contradictory forms of expression that exist for each function.
Repressed functions will take on the opposing attitude of the conscious/dominant which represses it.
One inferior function will arise as auxiliary, because of the prior stated rule that consciousness requires P and J input/output.
As the auxiliary becomes more conscious, it gains a stronger footing in the psyche, and with it, the ability to further influence the attitudes of its repressed partner-function. This produces the 'tertiary'.
The emergence of the tertiary as defined by the auxiliary has produced a unique arrangement which is now known as a 'type' (1/16).
Consciousness is a wave-form that is characterized by interference patterns between two orthogonal (P/J) wave progressions/partial differential equations, each of which is actually an expression of polarity between the other function in its own category (T<>F and S<>N). It never exists in a steady state, only wave-like probabilities and approximations; to analyze the wave in a moment in time is to lose the essence of the interference pattern.
