Modernism and postmodernism might be characterised as the two major forces of philosophical thought that have influenced and continue to influence the changes in thinking in research methods. Modernism is associated with the scientific understanding of truth and knowledge, claiming that there is one ultimate, objective truth; and postmodernism relates to the human-centred holistic perspective, maintaining that there are subjective, multiple truths (Webster & Mertova, 2007: 11)
