Abstract

Scientific inference aims to understand the external world and the influence of our actions on it, and arises as an interaction of hypothesis, observation and inferential procedures. Of these, only the observations originate in the external world, although even they are the perceptions of the observer. Nonuniqueness poses a great problem to objective scientific inference; this book discusses the causes of nonuniqueness and suggests that they are not entirely removable. It argues that truth is not manifest and that progress in science is not sequential but is achieved by tentative theorisation and systematic error elimination.
