Looking back, I ask myself why so little of the basic research has had an impact on professional practice. - Brian Campbell Vickery

Mass communications analysts concentrate on “who sends what information, for what purposes, through what channels, to which people, with what effect”. The information profession is more interested in “who seeks what information, for what purposes, through what channels, from which people and sources, with what success”.

Interaction is the mode of life of living organisms. Each must feed on its environment, ingesting chemicals or other organisms. This is something more than "interaction", it is activity directed towards the environment. Since the organism must be selective in what it ingests, it needs to discriminate among the entities in its environment. From very primitive forms of discrimination, the sensory mechanisms of organisms have evolved into the senses of man, interpreted by an internal cognitive apparatus, memories of past experiences, and an ability to take rational decisions. By "rational" I mean activity that achieves intended results because it is based on a reliable understanding of the nature of the environment. In interacting with each other to carry out tasks jointly, men have further developed language, leading to a shared understanding of the environment. This shared understanding is knowledge.

Perhaps an underlying cause [of doubt as to the future of information science] is in some cases... the apprehension that information science may become “submerged” in the larger field of computer science.
