Approximate Truth and Descriptive Nesting
There is good reason to suppose that our best physical theories, quantum mechanics and special relativity, are false if taken together and literally. If they are in fact false, then how should they count as providing knowledge of the physical world? One might imagine that, while strictly false, our best physical theories are nevertheless in some sense probably approximately true. This paper pre...
متن کاملApproximate truth and Łukasiewicz logic
Lukasiewicz' infinite-valued logic L has been used by a number of authors to study reasoning with vague, "fuzzy", or uncertain statements ([5], [2], [11], [12]). Scott and, more recently, Katz have also argued that L is appropriate for the logic of degrees of error or degrees of approximation to the truth ([6], p. 421 and [4], p. 773). The aim of this note is to show that L is not appropriate f...
متن کاملApproximate Truth in Economic Modelling
94<100 words) Economic intuitions concerning rational behaviour in interactive social situations are shaped by idealized models which are regarded as “approximately true”. But ideal models cannot be meaningfully deemed approximately true unless asymptotically convergent processes imply them as limit cases. We illustrate by various examples – infinitely patient customers on durable monopoly mark...
متن کاملBayesian Statistical Inference and Approximate Truth
Scientists and Bayesian statisticians often study hypotheses that they know to be false. This creates an interpretive problem because the Bayesian probability of a hypothesis is supposed to represent the probability that the hypothesis is true. I investigate whether Bayesianism can accommodate the idea that false hypotheses are sometimes approximately true or that some hypotheses or models can ...
متن کاملTruth Degrees Theory and Approximate Reasoning in 3-Valued Propositional Pre-Rough Logic
By means of the function induced by a logical formula A, the concept of truth degree of the logical formula A is introduced in the 3-valued pre-rough logic in this paper. Moreover, similarity degrees among formulas are proposed and a pseudometric is defined on the set of formulas, and hence a possible framework suitable for developing approximate reasoning theory in 3-value logic pre-rough logi...
