Ordinary language and absolute certainty

Ordinary language in memoriam

Taking as a point of departure a recently published collection of representative contributions from various philosophers who claim to ‘proceed from ordinary language’, this article examines ordinary language philosophy in the light of some of the claims made by these philosophers. The claims are criticized mainly for failing to account for the variability of the use of terms in respect both of depth of intention and special contexts. These factors are such as to render the claims in question false when interpreted as significant assertions about language, but trivial when they are interpreted as reasonable and true.     

Ordinary language semantics: the contribution of Brentano and Marty

ABSTRACT

This paper examines the account of ordinary language semantics developed by Franz Brentano and his pupil Anton Marty. Long before the interest in ordinary language in the analytic tradition, Brentanian philosophers were exploring our everyday use of words, as opposed to the scientific use of language. Brentano and Marty were especially interested in the semantics of (common) names in ordinary language. They claimed that these names are vague, and that this is due to the structure of the concepts that constitute their meaning: concepts expressed by such names are themselves vague, based on typicality, and have more or less similar items within their extension. After presenting the views of Brentano and Marty, this paper compares them to later accounts of meaning and concepts, notably Wittgenstein’s theory of family resemblances and the prototype theory of concepts, and emphasizes the originality of the Brentanian position.     

Between uncertainty and certainty

In this study, 10 hematologists and 10 lung oncologists were interviewed regarding the information they provide to patients in four situations of uncertainty: determining the treatment that is in the patient's best interest; recurrence or progression of the patient's disease; determining when to withdraw life-prolonging treatment; discussing death, addressing questions such as whether the patient will die from the disease, and when. The primary finding is that delivery of information to patients with low survival rates can be improved by more and better disclosure by physicians at an earlier stage. The crucial point for physicians is to ascertain the wishes of patients, to learn what to reveal about what patients should expect, short term and long term, as death approaches.     

Probability,certainty and illusions

Some philosopheis (e.g. Ayer, Reichenbach, Lewis) use a version of the argument from illusion to prove that empirical statements are never certain. But this argument, unwittingly, also calls into doubt the certainty of calculations in logic and mathematics. The argument seems to call into question the application of any rule on the grounds that one might at some future time find out that one had misapplied it. But the argument from illusion is only the illusion of an argument.     

Knowledge,certainty and probability

In this essay, I discuss some of the important logical principles governing the concepts of knowledge, certainty and probability. In the first section, I suggest a series of definitions of epistemic terms, employing as primitive the locution ‘p is epistemi‐cally possible to S’ In the second section, I develop an epistemic concept of probability and compare it to the concepts of certainty and knowledge. In the third section, I relate the epistemic concepts of certainty and probability to the quantifiers of traditional logic and to a non‐episteznic concept of probability. I conclude by noting similarities and differences between the two concepts of probability.     

Knowledge,certainty, and assertion

Researchers have debated whether knowledge or certainty is a better candidate for the norm of assertion. Should you make an assertion only if you know it's true? Or should you make an assertion only if you're certain it's true? If either knowledge or certainty is a better candidate, then this will likely have detectable behavioral consequences. I report an experiment that tests for relevant behavioral consequences. The results support the view that assertability is more closely linked to knowledge than to certainty. In multiple scenarios, people were much more willing to allow assertability and certainty to come apart than to allow assertability and knowledge to come apart.     

Ordinary language: The contributions of Gilbert Ryle and John Austin to the experimental analysis of behavior

The aim of this paper is to show how "conceptual analysis"-the philosophical method used by Gilbert Ryle and John Austin-can contribute to behavior analysis in general and in particular to the elucidation and development of views put forward by B. F. Skinner. One of the key requirements is a sensitivity to the precise circumstances in which particular combinations of words are uttered. Without such sensitivity, it is difficult to make informed decisions as to when ways of talking should be changed and when they should be left as they are.
