The Anti-Essentialism Paper
The New Pragmatism, Anti-essentialism, and What is Universal: It’s The Situation All The Way Down C. F. Abel Stephen F. Austin State University [email protected] The New Pragmatism, Anti-essentialism, and What is Universal: It’s The Situation All The Way Down C. F. Abel Stephen F. Austin State University [email protected] A well-known scientist once gave a public lecture on astronomy. He described how the Earth orbits around the sun and how the sun, in turn, orbits around the center of a vast collection of stars called our galaxy. At the end of the lecture, a little old lady at the back of the room got up and said: "What you have told us is rubbish. The world is really a flat plate supported on the back of a giant tortoise." The scientist gave a superior smile before replying, "What is the tortoise standing on?" "You're very clever, young man," said the old lady. "But it's turtles all the way down!" Introduction “New Pragmatism” attacks the very foundation of pragmatic thought by denying that we may ever have any definitive experience. As what we are experiencing is up for grabs, we can never know any situation that we may encounter, and we are left to ground both our knowledge and our values in our language games alone. This paper argues that this set of claims is founded on two errors, one regarding the nature of language games and the other regarding the nature of deconstruction. The “Old Pragmatism,” by way of contrast, is non-essentialist but not anti- essentialist, and it resolves the problem of how we might know “the situation,” given the subjectivity of our observations and the contingencies of our language games, by suggesting that our experiences can be understood as existing in, and constituted by, the totality of their particular instances or modes at the time of inquiry. -

A301G What Is Science?
Astronomy 301G: Revolutionary Ideas in Science Getting Started What is Science? Reading Assignment: What’s the Matter? Readings in Physics • Foreword & Introduction • Richard Feynman (1918-1988 CE) “The Uncertainty of Science” • Aristotle (384-322 BCE) “The Science of Nature” ..... and also take a first look at Aristotle’s “Moving Things” Make an effort to formulate answers to the “Discussion Questions” at the end of each selection. (Suggestion: Look at these questions before you first read the selections.) What is Science? Science is the systematic study of the physical world. Qualification: “Science” = “Natural Science” Science is based upon observations of that world. Science is empirical and progressive. It involves the formulation and testing of hypotheses. Science attempts to explain natural phenomena. Goals and Objectives To gather information through observation and experiment To organize and systematize that knowledge To infer the the “laws of nature” which govern natural events The Domain of Science Physical Reality Science deals only with physical (“real”) objects and events, those which are either directly observable or whose existence can be inferred indirectly from observations. Observations must generally be reproducible (“witnessable”) to be considered real. (cf. ghosts, hallucinations, beliefs, ....) Note: Single (past) non-reproducible events or observations can sometimes be accepted as “real” if supported by a suitably large body of evidence. Factual Knowledge (“Data”) Information whose accuracy has been confirmed again and again by repeated observation or experiment. This “Information” can include fundamental principles, testable hypotheses, as well as directly observed events, processes and connections. The Working Assumptions of Science The Universe is Causal: Natural phenomena have natural causes which precede them. -
Principles of Scientific Inquiry
Chapter 2 PRINCIPLES OF SCIENTIFIC INQUIRY Introduction This chapter provides a summary of the principles of scientific inquiry. The purpose is to explain terminology, and introduce concepts, which are explained more completely in later chapters. Much of the content has been based on explanations and examples given by Wilson (1). The Scientific Method Although most of us have heard, at some time in our careers, that research must be carried out according to “the scientific method”, there is no single, scientific method. The term is usually used to mean a systematic approach to solving a problem in science. Three types of investigation, or method, can be recognized: · The Observational Method · The Experimental (and quasi-experimental) Methods, and · The Survey Method. The observational method is most common in the natural sciences, especially in fields such as biology, geology and environmental science. It involves recording observations according to a plan, which prescribes what information to collect, where it should be sought, and how it should be recorded. In the observational method, the researcher does not control any of the variables. In fact, it is important that the research be carried out in such a manner that the investigations do not change the behaviour of what is being observed. Errors introduced as a result of observing a phenomenon are known as systematic errors because they apply to all observations. Once a valid statistical sample (see Chapter Four) of observations has been recorded, the researcher analyzes and interprets the data, and develops a theory or hypothesis, which explains the observations. The experimental method begins with a hypothesis. -

It achieves this status in physics because it provides unification for contradictory laws of physics, namely quantum mechanics and general relativity. While based on advanced theoretical mathematics, its public discourse is growing in prevalence and its rhetorical power is leading to a scientific revolution, even among the public. -
Hempel and Confirmation Theory
Hempel and Confirmation Theory Jan Sprenger* June 15, 2020 Carl Gustav Hempel (1905–1997) was one of the primary exponents of logical empiricism. As a student and member of the Gesellschaft für em- pirische Philosophie in Berlin, alongside Reichenbach and Grelling, he wit- nessed the emergence of logical empiricism as a philosophical program. From the mid-1930s onwards, his contributions shaped its development, too. Hempel studied primarily in Göttingen and Berlin, but in 1929/30, he also spent a semester in Vienna studying with Carnap and partici- pated in the activities of the Vienna Circle. Both societies joined forces for organizing scientific events, and founded the journal Erkenntnis in 1930, where many seminal papers of logical empiricism were published, with Carnap and Reichenbach as editors. While the work of the Berlin philosophers is congenial to the project of the Vienna Circle, there are important differences, too. Neither Hempel nor his mentor Reichenbach identified “scientific philosophy” with the project of cleansing science of meaningless statements (e.g., Carnap 1930). Rather, Hempel extensively used a method that Carnap would apply in later works on probability and confirmation (Carnap 1950, 1952): expli- cation, that is, the replacement of a vague and imprecise pre-theoretical concept (e.g., “confirmation”) by a fruitful and precise concept (e.g., a formal confirmation criterion). Relying on the method of explication, Hempel developed adequacy conditions on a qualitative concept of con- firmation (Hempel 1943, 1945a,b), a probabilistic measure of degree of *Contact information: Center for Logic, Language and Cognition (LLC), Department of Philosophy and Education Sciences, Università degli Studi di Torino, Via Sant’Ottavio 20, 10124 Torino, Italy. -
This Is Dr. Chumney. the Focus of This Lecture Is Hypothesis Testing –Both What It Is, How Hypothesis Tests Are Used, and How to Conduct Hypothesis Tests
TRANSCRIPT: This is Dr. Chumney. The focus of this lecture is hypothesis testing –both what it is, how hypothesis tests are used, and how to conduct hypothesis tests. 1 TRANSCRIPT: In this lecture, we will talk about both theoretical and applied concepts related to hypothesis testing. 2 TRANSCRIPT: Let’s being the lecture with a summary of the logic process that underlies hypothesis testing. 3 TRANSCRIPT: It is often impossible or otherwise not feasible to collect data on every individual within a population. Therefore, researchers rely on samples to help answer questions about populations. Hypothesis testing is a statistical procedure that allows researchers to use sample data to draw inferences about the population of interest. Hypothesis testing is one of the most commonly used inferential procedures. Hypothesis testing will combine many of the concepts we have already covered, including z‐scores, probability, and the distribution of sample means. To conduct a hypothesis test, we first state a hypothesis about a population, predict the characteristics of a sample of that population (that is, we predict that a sample will be representative of the population), obtain a sample, then collect data from that sample and analyze the data to see if it is consistent with our hypotheses. 4 TRANSCRIPT: The process of hypothesis testing begins by stating a hypothesis about the unknown population. Actually we state two opposing hypotheses. The first hypothesis we state –the most important one –is the null hypothesis. The null hypothesis states that the treatment has no effect. In general the null hypothesis states that there is no change, no difference, no effect, and otherwise no relationship between the independent and dependent variables. -
The Scientific Method: Hypothesis Testing and Experimental Design
Appendix I The Scientific Method The study of science is different from other disciplines in many ways. Perhaps the most important aspect of “hard” science is its adherence to the principle of the scientific method: the posing of questions and the use of rigorous methods to answer those questions. I. Our Friend, the Null Hypothesis As a science major, you are probably no stranger to curiosity. It is the beginning of all scientific discovery. As you walk through the campus arboretum, you might wonder, “Why are trees green?” As you observe your peers in social groups at the cafeteria, you might ask yourself, “What subtle kinds of body language are those people using to communicate?” As you read an article about a new drug which promises to be an effective treatment for male pattern baldness, you think, “But how do they know it will work?” Asking such questions is the first step towards hypothesis formation. A scientific investigator does not begin the study of a biological phenomenon in a vacuum. If an investigator observes something interesting, s/he first asks a question about it, and then uses inductive reasoning (from the specific to the general) to generate an hypothesis based upon a logical set of expectations. To test the hypothesis, the investigator systematically collects data, either with field observations or a series of carefully designed experiments. By analyzing the data, the investigator uses deductive reasoning (from the general to the specific) to state a second hypothesis (it may be the same as or different from the original) about the observations. -

While a few early chapters are historically organized, my goal in the historical chapters is to trace a developmental progression of thought that introduces basic philosophical methods and frames issues that remain relevant today. Later chapters are topically organized. These include philosophy of science and philosophy of mind, areas where philosophy has shown dramatic recent progress. This text concludes with four chapters on ethics, broadly construed. I cover traditional theories of right action in the third of these. Students are first invited first to think about what is good for themselves and their relationships in a chapter of love and happiness. Next a few meta-ethical issues are considered; namely, whether they are moral truths and if so what makes them so. -
Turns in the Evolution of the Problem of Induction*
CARL G. HEMPEL TURNS IN THE EVOLUTION OF THE PROBLEM OF INDUCTION* 1. THE STANDARD CONCEPTION: INDUCTIVE "INFERENCE" Since the days of Hume's skeptical doubt, philosophical conceptions of the problem of induction and of ways in which it might be properly solved or dissolved have undergone a series of striking metamor- phoses. In my paper, I propose to examine some of those turnings, which seem to me to raise particularly important questions about the nature of empirical knowledge and especially scientific knowledge. Many, but by no means all, of the statements asserted by empirical science at a given time are accepted on the basis of previously established evidence sentences. Hume's skeptical doubt reflects the realization that most of those indirectly, or inferentially, accepted assertions rest on evidence that gives them no complete, no logically conclusive, support. This is, of course, the point of Hume's obser- vation that even if we have examined many occurrences of A and have found them all to be accompanied by B, it is quite conceivable, or logically possible, that some future occurrence of A might not be accompanied by B. Nor, we might add, does our evidence guarantee that past or present occurrences of A that we have not observed were- or are- accompanied by B, let alone that all occurrences ever of A are, without exception, accompanied by B. Yet, in our everyday pursuits as well as in scientific research we constantly rely on what I will call the method of inductive ac- ceptance, or MIA for short: we adopt beliefs, or expectations, about empirical matters on logically incomplete evidence, and we even base our actions on such beliefs- to the point of staking our lives on some of them.
