This autobiographical piece is in response to Frank Fair’s kind invitation to write a reflective piece on my involvement over the last 30 years in the critical thinking movement, with special attention given to 18 years of assessment data as I assessed students’ critical thinking outcomes at Baker University. The first section of the paper deals with my intellectual history and how I came to a specific understanding of CT. The second deals with the Baker Experiment in combining instruction in (...) CT with written composition, with a special focus on Deductive Reconstruction. The third section goes over our attempts at assessment and what we discovered by using three separate tests. The final section of the paper presents my conclusions about the challenges of teaching CT based on the Baker Experiment. (shrink)

Critical thinking is considered an essential educational goal. As a result, many philosophers dreamed their departments would offer multiple sections of CT, hence justifying hiring additional staff. Unfortunately, this dream did not materialize. So, similar to a current theory about teaching writing, “critical thinking across the curriculum” has become a popular idea. While the idea has appeal and unquestionable merit, I will argue that the likelihood the skills necessary for effective CT will actually be taught is minimal.

After critiquing the arguments against using formal logic to teach critical thinking, this paper argues that for theoretical, practical, and empirical reasons, instruction in the fundamentals of formal logic is essential for critical thinking, and so should be included in every class that purports to teach critical thinking.

Since the 80s, educators have supported instruction in critical thinking as “an Educational Ideal.” This should not be a surprise given some of the more common conceptions, e.g., Ennis’s “reasonable reflective thinking on what to believe or do,” or Siegel’s “being appropriately moved by reasons,” as opposed to bias, emotion or wishful thinking. Who would want a doctor, lawyer, or mechanic who could not skillfully evaluate arguments, causes, and cures? So, educators endorsed the dream that, through proper CT instruction, students’ (...) critical skills and “rational passions” could be greatly improved. In spite of the dream’s appeal, the reality is, after 30+ years, there is little reason to think the dream resembles reality. After describing what I take to be an adequate definition of CT, such a depressing conclusion will be supported by CT assessment scores from across academe, the continued widespread disagreement among experts in nearly all fields, including CT, and the abundant psychological research on rationality and decision making. And finally, while the ideal extols the value of objectivity, I shall argue that bias may be unavoidable because personal values play a vital role in the evaluation of many arguments. (shrink)

Some researchers have claimed that there is no significant correlation between students’ majors and their performance on standardized critical thinking tests. This paper provides both evidence and arguments that that claim may well be false. Besides arguments based on the correlation between students’ majors and other standardized tests, data from Baker University’s Critical Thinking and Writing Program show large differences in effect size gains relative to students’ majors.

In this paper, after showing how the postmodern critiques of Enlightenment rationality apply to critical thinking, I argue that a critical discussion on any subject must assume specific principles of rationality. I then show how these principles can be used to critique and reject postmodern claims about the contextual nature of rationality.

This paper provides evidence and arguments that, given the choice of teaching critical thinking and written composition as separate, stand-alone courses or combining them, the two should be combined into an integrated sequence.

In "The Problem with Percy: Epistemology, Understanding and Critical Thinking," Sharon Bailin argues that critical thinking skills do not generalize because students do not understand the larger epistemological picture in which to situate the importance of arguments and reasons. More plausible explanations are: (I) instructors across the disciplines do not give assignments requiring critical thinking (CT) skills, (2) single courses in CT have little effect, (3) pragmatic arguments showing the effectiveness of CT are more effective than epistemological arguments with the (...) average student. So to achieve the generalization of the logical skills and intellectual dispositions inherent in CT courses, CT thinking cannot be departmentalized. (shrink)

After summarizing Plantinga’s critique of “classical foundationalism” and his substitute, Reformed epistemology, the paper argues that Reformed epistemology has so many problems that it is not an adequate substitute for classical foundationalism. Given Plantinga’s reformed epistemology, believers of any religion could have “knowledge of their God.” This is because Plantinga has not set forth the justifying conditions necessary to distinguish between “properly basic beliefs” as opposed to improperly basic beliefs. Given such problems, it is more reasonable to stick with classical (...) foundationalism rather than Plantinga’s substitute. (shrink)

Over the last few years, there have been five best sellers critical of religion and religious belief. It seems that there is great interest in questions about religious belief. Ironically, critical thinking texts seldom examine the topic. This paper will evaluate eight arguments to exempt religious belief from rational critique. I conclude that the topic of religious belief should not be exempt from critical thinking classes.

This is a brief response to David Wright’s commentary on my paper, “Critical Thinking Instruction: A Realistic Evaluation: The Dream vs. Reality.” Wright claims that if one looks more closely at the literature on critical thinking assessment that the reported effect sizes for CT instruction are quite respectable and my standards are too high. My comments will focus is on whether effect size is both problematic and an adequate measure for assessment.

The late Richard Paul was arguably the most well-known and influential person in the history of the critical thinking movement. This reflection on and tribute to his work focuses on Paul’s genius in applying his knowledge of important works in the history of philosophy to the development of a robust conception of critical thinking, one that has wide appeal, not only to philosophers, but to faculties across academe. I also discuss the debt so many of us who teach critical thinking (...) owe to his amazing scholarly and organizational skills, e.g., the 36 years of the Conference on Critical Thinking and Educational Reform, his in-service work for hundreds of faculties, his distribution of over one million “Thinkers Guides,” and his successful efforts to make critical thinking the core concept in education.

Recently, there have been at least five best sellers critical of religion and religious belief. It seems, at least among readers in the U.S., that there is great interest in questions about the rationality of religious belief. Ironically, critical thinking texts seldom examine the topic. After reviewing a series of previous arguments that people have an ethical duty to think critically, this paper will evaluate a number of arguments intended to exempt religious belief from the sorts of rational critique covered (...) in critical thinking classes. After critiquing each argument, I conclude that the proper scope of critical thinking should include religious beliefs. In summary, if people have an ethical duty to think critically about important beliefs and religious beliefs are indeed important, then people have an obligation to think critically about religious beliefs. Nothing in the paper addresses the question of whether it is or is not rational to endorse a religion. (shrink)

While all who are interested in the philosophical issues surrounding feminism should read Simone de Beauvoir's seminal work The Second Sex, many who begin the long journey do not understand the philo- sophical traditions from which her analyses and arguments grow. This makes understanding and appreciating the cogency of her position very difficult. Understanding The Second Sex introduces the naive reader to the necessary philosophical tradition, explicates major portions of the text, and analyzes Simone de Beauvoir's criticisms of marriage and (...) romantic love.

Chapin reviewed this 1972 ZEITSCHRIFT paper that proves the completeness theorem for the logic of variable-binding-term operators created by Corcoran and his student John Herring in the 1971 LOGIQUE ET ANALYSE paper in which the theorem was conjectured. This leveraging proof extends completeness of ordinary first-order logic to the extension with vbtos. Newton da Costa independently proved the same theorem about the same time using a Henkin-type proof. This 1972 paper builds on the 1971 “Notes on a Semantic Analysis of (...) Variable Binding Term Operators” (Co-author John Herring), Logique et Analyse 55, 646–57. MR0307874 (46 #6989). A variable binding term operator (vbto) is a non-logical constant, say v, which combines with a variable y and a formula F containing y free to form a term (vy:F) whose free variables are exact ly those of F, excluding y. Kalish-Montague 1964 proposed using vbtos to formalize definite descriptions “the x: x+x=2”, set abstracts {x: F}, minimization in recursive function theory “the least x: x+x>2”, etc. However, they gave no semantics for vbtos. Hatcher 1968 gave a semantics but one that has flaws described in the 1971 paper and admitted by Hatcher. In 1971 we give a correct semantic analysis of vbtos. We also give axioms for using them in deductions. And we conjecture strong completeness for the deductions with respect to the semantics. The conjecture, proved in this paper with Hatcher’s help, was proved independently about the same time by Newton da Costa. (shrink)

What is the relation between a reason and an action when the reason explains the action by giving the agent's reason for doing what he did? We may call such explanations rationalizations, and say that the reason rationalizes the action. In this paper I want to defend the ancient - and common-sense - position that rationalization is a species of ordinary causal explanation. The defense no doubt requires some redeployment, but not more or less complete abandonment of the position, as (...) urged by many recent writers. (shrink)

Davidson attacks the intelligibility of conceptual relativism, i.e. of truth relative to a conceptual scheme. He defines the notion of a conceptual scheme as something ordering, organizing, and rendering intelligible empirical content, and calls the position that employs both notions scheme-content dualism. He argues that such dualism is untenable since: not only can we not parcel out empirical content sentence per sentence but also the notion of uninterpreted content to which several schemes are relative, and the related notion of a (...) theory ”fitting the evidence’, can be shown to lack intelligibility too. Davidson argues further that belief in incommensurable schemes or non-intertranslatable languages is possible only on violating a correct understanding of interpretability : if we succeed in interpreting someone else then we have shown there is no need to speak of two conceptual schemes, while if we fail ”there is no ground for speaking of two.’.

David Hume is famous as a sceptical philosopher but the nature of his scepticism is difficult to pin down. Hume's True Scepticism provides the first sustained interpretation of Part 4 of Book 1 of Hume's Treatise: his deepest engagement with sceptical arguments, in which he notes that, while reason shows that we ought not to believe the verdicts of reason or the senses, we do so nonetheless. Donald C. Ainslie addresses Hume's theory of representation; his criticisms of Locke, Descartes, (...) and other predecessors; his account of the imagination; his understanding of perceptions and sensory belief; and his bundle theory of the mind and his later rejection of it.
