 Quantitative approaches to information as range also have their origins in the inverse relationship principle. To restate—the motivation being that the less likely the truth of a proposition as expressed in a logical language with respect to a particular domain, the greater the amount of information encoded by the relevant formula. This is in contrast to the information measures in the mathematical theory of communication (Shannon 1953 [1950]) where such measures are gotten via an inverse relationship on the expectation of the receiver \(R\) of the receipt of a signal from some source \(S\).
