Mind (The Culture)

In Iain M. Banks' Culture series, most larger starships, some inhabited planets and all orbitals have their own Minds: sentient, hyperintelligent machines originally built by biological species, which have evolved, redesigned themselves, and become many times more intelligent than their original creators.

These Minds have become an indispensable part of the Culture, enabling much of its post-scarcity amenities by planning and automating society (controlling day-to-day administration with mere fractions of their mental power). The main feature of these Minds—in comparison to extremely powerful artificial intelligences in other fiction—is that the Minds are (by design and by extension of their rational, but "humanistic" thought processes) generally a very benevolent presence, and show no wish to supplant or dominate their erstwhile creators. Though this is commonly viewed in a utopian light, a view where the human members of the Culture amount to little more than pets is not unsupportable.

Although the Culture is a type of utopian anarchy, Minds most closely approach the status of leaders, and would likely be considered godlike in less rational societies. As independent, thinking beings, each has its own character, and indeed, legally (insofar as the Culture has a 'legal system'), each is a Culture citizen. Some Minds are more aggressive, some more calm; some don't mind mischief, others simply demonstrate intellectual curiosity. But above all they tend to behave rationally and benevolently in their decisions.

As mentioned before, Minds can serve several different purposes, but Culture ships and habitats have one special attribute: the Mind and the ship or habitat are perceived as one entity; in some ways the Mind is the ship, certainly from its passengers' point of view. It seems normal practice to address the ship's Mind as "Ship" (and an Orbital hub as "Hub"). However, a Mind can transfer its 'mind state' into and out of its ship 'body', and even switch roles entirely, becoming (for example) an Orbital Hub from a warship.
