A diachronic display consists of two chronologically successive state descriptions of theory statements for the same problem defined by the same test design and therefore addressed by the same scientific profession. State descriptions contain statements and equations that operate as semantical rules displaying the meanings of the constituent terms and variables. Comparison of the statements and equations in the two chronologically separated state descriptions containing the same test design exhibits changes in meanings through time.

In computational philosophy of science this is a comparative-static semantical analysis, i.e., a comparison of a discovery system’s input and output state descriptions of theory statements. After the computer system is run the resulting output state description is of principal interest.
