Fuzzy Philosophy of Science

Scientific consequences are dependent on premises that are logical proportions of the phenomena concerned. These proportions are verbal and linguistic statements, and therefore, at the initial philosophical thinking they all include vagueness and imprecision. As more and more scientific evidence becomes available either rationally or empirically the validity degree these statements increases, or vagueness proportion decreases. In the philosophy of science so far scientific statements are either assumed as absolutely correct but more often they are accepted with some probability. However, objective probability attachment to scientific statements is a difficult task, and therefore, subjective (Bayesian) proportions are attached to these statements in practice. After a detailed account of what were the advocators and opponents to scientific absolute correctness and probability, a fuzzy thinking and consequently membership degree attachments rather than probability are presented by considering fuzzy subsets in this paper.
