Logic of information

&#9758; This page belongs to resource collections on Logic and Inquiry.

The logic of information, or the logical theory of information, considers the information content of logical signs &mdash; everything from bits to books and beyond &mdash; along the lines initially developed by Charles Sanders Peirce. In this line of development the concept of information serves to integrate the aspects of logical signs that are separately covered by the concepts of denotation and connotation, or, in roughly equivalent terms, by the concepts of extension and comprehension.

Peirce began to develop these ideas in his lectures &ldquo;On the Logic of Science&rdquo; at Harvard University (1865) and the Lowell Institute (1866). Here is one of the starting points:
