Tao meta-learning

The application of theory of logical types by Russell and Whitehead was developed by Bateson in the description of learning, with following recursion orders leading to meta-logical levels of learning:

Zero learning is characterized by specificity of response, which—right or wrong—is not subject to correction.

Learning I is change in specificity of response by correc­tion of errors of choice within a set of alternatives.

Learning II is change in the process of Learning I, e.g., a corrective change in the set of alternatives from which choice is made, or it is a change in how the sequence of experience is punctuated.

Learning III is change in the process of Learning II, e.g., a corrective change in the system of sets of alternatives from which choice is made. (We shall see later that to demand this level of performance of some men and some mammals is sometimes pathogenic.)

Learning IV would be change in Learning III, but prob­ably does not occur in any adult living organism on this earth. Evolutionary process has, however, created organisms whose ontogeny brings them to Level III. The combination of phylogenesis with ontogenesis, in fact, achieves Level IV.
