THE LIMITS OF PRAGMATISM AND THE LIMITS OF REALISM

Abstract. I argue here for a limited version of pragmatism—called conceptual pragmatism—that recognizes that conceptual systems are to be evaluated according to their usefulness for helping us get around in the world. Once a conceptual system is in place, however, the truth of sentences is a matter of both empirical tit and coherence with the rest of our knowledge. The error of critical realists is to fail to take into account the limited conceptual relativity that is to be expected on the basis of conceptual pragmatism. The conceptual realist thesis applies equally in science and theology.     

RIGHTS AND RESPONSIBILITIES ON THE HOME PLANET

Abstract. Earth is the home planet, right for life. But rights, a notable political category, is, unfortunately, a biologically awkward word. Humans, nonetheless, have rights to a natural environment with integrity. Humans have responsibilities to respect values in fauna and flora. Appropriate survival units include species populations and ecosystems. Increasingly the ultimate survival unit isglobal; and humans have a responsibility to the planet Earth. Human political systems are not well suited to protect life atglobal ranges. National boundaries ignore important ecologicalprocesses; national policies do not favor an equitable distribution of sustainable resources. But there are signs of hope.     

The logic of the medical research article

As do all forms of science, medical theories have a factual as well as a logical basis. New information is presented in medical research articles. These papers have three separate arguments: the argument of the hypothesis, the argument of the experimental protocol, and the argument of the hypothesis's judgment. These arguments may be examples of the hypothetico-deductive or confirmational model of scientific inference. The logical form of these arguments are informal and inductive rather than formal and deductive. Understanding the nature of the logic of the medical research article may help avoid erroneous conclusions.     

Substitutability between conditioned and primary reinforcers in discrimination acquisition.

Rats and pigeons were trained on a series of reversals of a conditional simultaneous discrimination. The percentage of reinforcement for correct trials was varied across reversals. When nonreinforced correct trials produced the same feedback as incorrect trials, the number of errors to reach an acquisition criterion was greater for smaller percentages of reinforcement, but the number of reinforcers required was either approximately constant or smaller for the smaller percentages. When a stimulus paired with food (the conditioned reinforcer) was added on nonreinforced correct trials, both measures were substantially decreased. When the same stimulus was presented, but without a history of food pairing, learning rate was similar to when no stimulus was presented on nonreinforced trials. The results provide direct evidence that conditioned reinforcers may substitute, although imperfectly, for a primary reinforcer, and that pairing with the primary reinforcer is a necessary condition for such substitutability to occur.     

Behavior analysis/modification for everyone

This paper presents a very brief overview of people's attempt to understand and change behavior and shows how behavior analysis is different from these views. The importance of everyone knowing and using behavioral principles in their everyday life is stressed and the opposition to a behavioral approach is discussed. The aims of the organization called Behavior Analysis/Modification in the Regular Classroom is presented and some steps that this organization is following in an attempt to help to disseminate the knowledge and use of behavioral principles in the schools is presented.     

The potential of medicine as a resource for philosophy

In addition to the neglect of philosophy by medicine, emphasized in a recent editorial in this journal, there has been an equally important neglect of medicine by philosophy. Philosophy stands to gain from medicine in three respects: in materials, the conceptual difficulties arising in the practice of medicine being key data for philosophical enquiry; in methods, these data, through their problematic character, being ideally suited to the technique of linguistic analysis; and in results, the practical requirements of medicine placing a direct demand for progress on philosophical theory. The future of the relationship between philosophy and medicine depends on the development of a positive two-way trade between them.     

Oral behavioral patterns in facial pain, headache and non-headache populations

Patterns of oral behavior have been suggested as factors leading to head and facial pain. The present study evaluated the frequency with which certain oral habits were self-reported by five groups of Ss: Facial Pain. Tension Headache, Migraine Headache, Combined Migraine and Tension Headache and No Pain. Four oral behavior patterns were found to be significantly different among groups. These were diurnal bruxism. thrusting the jaw forward, cupping the chin in the hand and resting the hand on the side of the face. When Ss were reclassified into those reporting no facial pain, temporomandibular joint (TMJ) pain, or a combination of TMJ and jaw muscle pain, the variables of diurnal bruxism and resting the hand on the side of the face were found to predict significantly both pain groups. However, the resting the hand factor was negatively weighted for the TMJ Pain group only. One other factor, nocturnal bruxism. was found to be self-reported at a significantly higher frequency in the Combined Facial Pain group compared to the No Facial Pain and TMJ Pain groups. Discussion focuses on the implications of the present findings on research in the facial pain and headache areas.     

There are higher levels of conspiracy beliefs in more corrupt countries

In four studies, I found evidence that people living in countries with higher levels of corruption have a greater tendency for conspiracy ideation. In Study 1 (21 countries, N = 20,207), participants living in more corrupt countries reported having higher COVID-19 and generic conspiracy beliefs. Study 2 (25 countries, N = 4935), Study 3 (25 countries, N = 24,424), and Study 4 (24 countries, N = 5973) replicated the same finding. Internal meta-analysis suggested that this association remained significant after adjusting for other relevant cross-country differences. Studies 1 and 2, but not 3 and 4, also showed that corruption moderated the association between individuals’ gullibility (i.e., lack of education) and their conspiracy beliefs, and this association was significant only in low-corruption countries. The findings suggest that country-level corruption breeds conspiracy beliefs and moderates the effect of individuals’ gullibility on conspiracy beliefs.
