Helmholtz’s Physiological Psychology

Hermann von Helmholtz (1821-1894) established results both controversial and enduring: analysis of mixed colors and of combination tones, arguments against nativism, and the analysis of sensation and perception using the techniques of natural science. The paper focuses on Helmholtz’s account of sensation, perception, and representation via “physiological psychology”. Helmholtz emphasized that external stimuli of sensations are causes, and sensations are their effects, and he had a practical and naturalist orientation toward the analysis of phenomenal experience. However, he argued as well that sensation must be interpreted to yield representation, and that representation is geared toward objective representation (the central thesis of contemporary intentionalism). The interpretation of sensation is based on “facts” revealed in experiment, but extends to the analysis of the quantitative, causal relationships between stimuli and responses. A key question for Helmholtz’s theory is the extent to which mental operations are to be ascribed a role in interpreting sensation

Who Should Parent? Parenting Fitness as Determined by the Five-factor Personality Module

The majority of parents in the United States engage in good enough parenting, which allows children to develop into functional and well-adjusted adults. However, as the Juvenile court system knows well, some parent\u27s do not engage in good enough parenting; some parents are very abusive or neglectful in their parenting styles. In 2012, and estimated 686,000 children were victims of child maltreatment. Can child abuse be prevented? Yes, it can. There is a strong correlation between an individual\u27s personality make up and the way they parent. Additionally, personality follows a predictable maturation trend and significant deficits within an individual\u27s personality will remain relatively constant unto that individual as he or she ages, if steps are not taken to intentionally alter those deficits. This indicates that a person\u27s ability to parent, and his or her likelihood of being a good enough or neglectful and abusive parent can be determined long before a person even has children, such as in late adolescence. This researcher sought to determine if the Five-Factor Personality module could be used to screen for individuals at risk of engaging in child maltreatment during late adolescence to prevent future child abuse and neglect

Epistemic authority and the gender lens

Researching 'hidden' forms of social inequality such as gender often poses particular challenges. Not least of these is how to uncover such dimensions of social life whilst preserving the perspectives of research participants, who may not consider such matters relevant to their lives, particularly if other forms of identity or oppression are more prominent for them. Here, I reflect on these issues in the context of researching user involvement in mental health services from a feminist perspective. I show how `uncovering' gender and other forms of social inequality in the field was aided through adopting a wide analytical lens focusing on power, along with reflexivity and openness in discussing my own political analysis and commitments in relation to the study area with the researched. I also describe how I attempted to resolve the epistemological-ethical issues involved through conceptualising these in terms of `situatedness' and gender salience and adopting a feminist standpoint which emphasised what researchers can, and indeed should, bring to the research enterprise. Related issues of power and empowerment in the research process are discussed

New Water in Old Buckets: Hypothetical and Counterfactual Reasoning in Mach’s Economy of Science

Ernst Mach’s defense of relativist theories of motion in Die Mechanik involves a well-known criticism of Newton’s theory appealing to absolute space, and of Newton’s “bucket” experiment. Sympathetic readers (Norton 1995) and critics (Stein 1967, 1977) agree that there’s a tension in Mach’s view: he allows for some constructed scientific concepts, but not others, and some kinds of reasoning about unobserved phenomena, but not others. Following Banks (2003), I argue that this tension can be interpreted as a constructive one, springing from Mach’s approach to scientific reasoning. Mach’s “economy of science” allows for a principled distinction to be made, between natural and artificial hypothetical reasoning, and Mach defends a division of labor between the sciences in a 1903 paper for The Monist, “Space and Geometry from the Point of View of Physical Inquiry”. That division supports counterfactual reasoning in Mach’s system, something that’s long been denied is possible for him

Chance in a Created World: How to Avoid Common Misunderstandings about Divine Action

In the article ”Against Physicalism-plus-God: How Creation Accounts for Divine Action in the World’, I defined a framework which allows us to make some progress in our understanding of how God acts in the world. In the present article, I apply this framework to the specific question of chance events. I show that chance does not provide an explanation for special divine action. Nevertheless, chance does not hamper God’s ability to act in the world, and creation provides a framework for the understanding of chance, which is akin to what we see in modern science

Cassirer and Steinthal on Expression and the Science of Language

Ernst Cassirer’s focus on the expressive function of language should be read, not in the context of Carnap’s debate with Heidegger, but in the context of the earlier work of Chajim (Heymann) Steinthal. Steinthal distinguishes the expressive form of language, when language is studied as a natural phenomenon, from language as a logical, inferential system. Steinthal argues that language always can be expressed in terms of logical inference. Thus, he would disagree with Heidegger, just as Carnap does. But, Steinthal insists, that is not to say that language, as a natural phenomenon, is exhausted by logic or by the place of terms or relations in inferential structures. Steinthal’s “form” of linguistic “expression” is an early version of Cassirer’s “expressive function” for language. The expressive function, then, should not be seen to place a barrier between Carnap and Cassirer. Rather, Steinthal and Cassirer deal with a question that, as far as I know, Carnap does not address directly: how should philosophers analyze human language as a natural phenomenon, as a part of our expression as animals? And how does that expression determine the semantic categories, kind terms, and other structures that develop within, and characterize, human language itself

Laws of Thought and Laws of Logic after Kant

George Boole emerged from the British tradition of the “New Analytic”, known for the view that the laws of logic are laws of thought. Logicians in the New Analytic tradition were influenced by the work of Immanuel Kant, and by the German logicians Wilhelm Traugott Krug and Wilhelm Esser, among others. In his 1854 work An Investigation of the Laws of Thought on Which are Founded the Mathematical Theories of Logic and Probabilities, Boole argues that the laws of thought acquire normative force when constrained to mathematical reasoning. Boole’s motivation is, first, to address issues in the foundations of mathematics, including the relationship between arithmetic and algebra, and the study and application of differential equations (Durand-Richard, van Evra, Panteki). Second, Boole intended to derive the laws of logic from the laws of the operation of the human mind, and to show that these laws were valid of algebra and of logic both, when applied to a restricted domain. Boole’s thorough and flexible work in these areas influenced the development of model theory (see Hodges, forthcoming), and has much in common with contemporary inferentialist approaches to logic (found in, e.g., Peregrin and Resnik)
