Definitions of "information"

The concept ''information'' has been defined by several theorists.

Peirce

Charles S. Peirce Charles Sanders Peirce ( ; September 10, 1839 – April 19, 1914) was an American philosopher, logician, mathematician and scientist who is sometimes known as "the father of pragmatism". Educated as a chemist and employed as a scientist for t ...

. For Peirce, information integrates the aspects of

s and expressions separately covered by the concepts of

denotation In linguistics and philosophy, the denotation of an expression is its literal meaning. For instance, the English word "warm" denotes the property of being warm. Denotation is contrasted with other aspects of meaning including connotation. For insta ...

and comprehension on the other.

Shannon and Weaver

Claude E. Shannon, for his part, was very cautious: "The word 'information' has been given different meanings by various writers in the general field of information theory. It is likely that at least a number of these will prove sufficiently useful in certain applications to deserve further study and permanent recognition. It is hardly to be expected that a single concept of information would satisfactorily account for the numerous possible applications of this general field." (Shannon 1993, p. 180). Thus, following Shannon, Weaver supported a tripartite analysis of information in terms of (1) technical problems concerning the quantification of information and dealt with by Shannon's theory; (2) semantic problems relating to meaning and truth; and (3) what he called "influential" problems concerning the impact and effectiveness of information on human behaviour, which he thought had to play an equally important role. And these are only two early examples of the problems raised by any analysis of information. A map of the main senses in which one may speak of information is provided by
the Stanford Encyclopedia of Philosophy article
The previous paragraphs are based on it.

Bateson

defined information as "a difference that makes a difference", which is based on Donald M. MacKay: information is a distinction that makes a difference.

Floridi

According to Luciano Floridi, four kinds of mutually compatible phenomena are commonly referred to as "information": * Information about something (e.g. a train timetable) * Information as something (e.g. DNA, or fingerprints) * Information for something (e.g. algorithms or instructions) * Information in something (e.g. a pattern or a constraint). The word "information" is commonly used so metaphorically or so abstractly that the meaning is unclear.
