Illingworth 1996, p. 527 Verification3 and validation [is] a general term for the complete range of checks that are performed on a system in order to increase confidence that the system is suitable for its intended purpose. This range might include a rigorous set of functional tests, performance testing, reliability testing, and so on, in which case the term verification, validation and testing is more appropraite. Although a precise distinction is not always drawn, the verification aspects normally refers to completely objective checking of conforming to some well-defined specification, while the validation aspect normally refers to a somewhat objective assessment of likely suitability in the intended environment.Eco 1998, p. 19 There exists a process of verification1 that is based on slow, collective, public performance by what Charles Sanders Pierce called 'the Community.' It is thanks to human faith in the work of this community that we can say, with some serenity, that the Donation of Constantine was false, that the earth turns around the sun, and that Saint Thomas at least knew the planet is round.
