The equality between the different expressions for subjective abduction is given below: The symbolic notation for subjective abduction is " Abductive reasoning (also called abduction, abductive inference, or retroduction) is a form of logical inference formulated and advanced by American philosopher Charles Sanders Peirce beginning in the last third of the 19th century.

(a) If statement A is the cause and statement B is its effect. T The completeness property means that every validity (truth) is provable. In other cases, no new law is suggested, but only a peculiar state of facts that will "explain" the surprising phenomenon; and a law already known is recognized as applicable to the suggested hypothesis, so that the phenomenon, under that assumption, would not be surprising, but quite likely, or even would be a necessary result.
