Introspective is a dance album, like Disco, but unlike Disco, the songs are new, not remixes of old songs. It is so named because "all the songs, although it's a dance album, are introspective". Perhaps the biggest changes in Pet Shop Boys' sound evident on this album are an increasing attention to orchestration, but these changes would reach a peak later, with Very.
Introspective was rereleased in 2001 (as were most of the group's albums up to that point) as Instrospective/Further Listening 1988-1989. The rereleased version was not only digitally remastered but came with a second disc of B-sides and previously unreleased material from around the time of the album's original release.
Introspection is the process by which someone comes to form beliefs about her own mental states.
As was the case with the infallibility claim, for this claim to be plausible it must presumably be limited to beliefs formed by introspection: if an individual believes on the basis of introspection that she is in a particular mental state, then her belief is justified.
Introspection should likewise be thought of as akin to the kind of theory-laden perception that often goes on in the physical sciences.
The introspective method has been adopted by psychologists from the earliest times, more especially by Hobbes, Locke, Berkeley, Hume, and English psychologists of the earlier school.
Such psychological problems as those connected with the emotions and their physical concomitants are especially defective in the introspective method; the fact that one is looking forward to a shock prepared in advance constitutes at once an abnormal psychic state, just as a nervous person's heart will beat faster when awaiting a doctor's diagnosis.
The purely introspective method has of course always been supplemented by the comparison of similar psychic states in other persons, and in modern psycho-physiology it is of comparatively minor importance.
