Hilary Kornblith is an American philosopher. He is a professor of philosophy at the University of Massachusetts Amherst and one of contemporary epistemology's most prominent proponents of naturalized epistemology.
Kornblith received his B.A. from State University of New York at Buffalo in 1975 and his PhD from Cornell University in 1980, where he studied under Sydney Shoemaker and Richard Boyd. Before coming to University of Massachusetts in 2003, Kornblith taught at the University of Vermont, where he also chaired the department from 1991 to 1997. His research interests include epistemology, metaphysics and the philosophy of mind. Apart from naturalized epistemology, his most recent work includes the role of intuitions in philosophical theorizing, the conflicts between internalism and externalism in epistemology, and the mental states of non-human animals.
In his 1993 book Inductive Inference and Its Natural Ground (MIT Press, 1993) Kornblith argues that inductive knowledge is possible by virtue of a fit between our innate psychological capacities and the causal structure of the world. Following Boyd, Kornblith takes the causal structure in question to be a structure of natural kinds, i.e., of homeostatically clustered properties. Such natural kinds provide a natural ground for inductive inference by virtue of the fact that our innate inferential tendencies (as revealed by empirical psychology) are structured in a way that assumes a world of natural kinds, and, thereby, tend to provide us with accurate beliefs about the world in an environment populated by such natural kinds.
Kornblith is perhaps most well known for his defense of the view that knowledge is a natural kind. This claim is defended in his book Knowledge and its Place in Nature (Oxford University Press, 2002) where Kornblith argues that knowledge, as it is being studied in cognitive ethology, is a sufficiently robust and inductively valuable category to qualify as a natural kind. Consequently, he claims, the proper method for epistemology is empirical, contrary to what has been assumed by most epistemologists, who traditionally have proceeded by way of conceptual analysis and the probing of intuitions rather than by way of empirical investigation.
Kornblith's case for knowledge as a natural kind provides the basis for his critique of philosophy as conceptual analysis. According to Kornblith, the proper object of philosophical analysis is not concepts, but the phenomena picked out by those concepts. At the same time, Kornblith's work in semantics indicates that his claims about conceptual analysis can, in fact, be motivated independently of his view on knowledge as a natural kind. In particular, he has argued that semantic externalism provides the correct semantics not only for natural kinds but also for artifactual kinds — a claim that, if true, would lend plausibility to the idea that empirical investigation provides a promising philosophical method, quite independently of whether or not a majority of the objects of philosophical inquiry turn out to be natural kinds.
Epistemology is the branch of philosophy concerned with knowledge. Contemporary philosophers consider it a major subfield of philosophy, along with ethics, logic, and metaphysics, which are more ancient subdivisions of philosophy. There are different views on the relation between epistemology, natural sciences and these ancient divisions of philosophy: William Alston considers that it has historically always been a part of cognitive psychology. Quine viewed epistemology as a chapter of psychologySect.1.1 whereas Russell viewed it as a mix of psychology and logic. In contrast, Popper, Carnap and others in the Vienna circle considered that only objective or intersubjective knowledge should be studied in epistemology.
In philosophy, empiricism is an epistemological view that holds that true knowledge or justification comes only or primarily from sensory experience. It is one of several competing views within epistemology, along with rationalism and skepticism. Empiricism emphasizes the central role of empirical evidence in the formation of ideas, rather than innate ideas or traditions. However, empiricists may argue that traditions arise due to relations of previous sensory experiences.
Foundationalism concerns philosophical theories of knowledge resting upon non-inferential justified belief, or some secure foundation of certainty such as a conclusion inferred from a basis of sound premises. The main rival of the foundationalist theory of justification is the coherence theory of justification, whereby a body of knowledge, not requiring a secure foundation, can be established by the interlocking strength of its components, like a puzzle solved without prior certainty that each small region was solved correctly.
Metaphilosophy, sometimes called the philosophy of philosophy, is "the investigation of the nature of philosophy". Its subject matter includes the aims of philosophy, the boundaries of philosophy, and its methods. Thus, while philosophy characteristically inquires into the nature of being, the reality of objects, the possibility of knowledge, the nature of truth, and so on, metaphilosophy is the self-reflective inquiry into the nature, aims, and methods of the activity that makes these kinds of inquiries, by asking what is philosophy itself, what sorts of questions it should ask, how it might pose and answer them, and what it can achieve in doing so. It is considered by some to be a subject prior and preparatory to philosophy, while others see it as inherently a part of philosophy, or automatically a part of philosophy while others adopt some combination of these views.
In its most common sense, philosophical methodology is the field of inquiry studying the methods used to do philosophy. But the term can also refer to the methods themselves. It may be understood in a wide sense as the general study of principles used for theory selection, or in a more narrow sense as the study of ways of conducting one's research and theorizing with the goal of acquiring philosophical knowledge. Philosophical methodology investigates both descriptive issues, such as which methods actually have been used by philosophers, and normative issues, such as which methods should be used or how to do good philosophy.
Willard Van Orman Quine was an American philosopher and logician in the analytic tradition, recognized as "one of the most influential philosophers of the twentieth century". He served as the Edgar Pierce Chair of Philosophy at Harvard from 1956 to 1978.
Rudolf Carnap was a German-language philosopher who was active in Europe before 1935 and in the United States thereafter. He was a major member of the Vienna Circle and an advocate of logical positivism. He is considered "one of the giants among twentieth-century philosophers."
Ethical intuitionism is a view or family of views in moral epistemology. It is foundationalism applied to moral knowledge, the thesis that some moral truths can be known non-inferentially. Such an epistemological view is by definition committed to the existence of knowledge of moral truths; therefore, ethical intuitionism implies cognitivism.
"Natural kind" is an intellectual grouping, or categorizing of things, in a manner that is reflective of the actual world and not just human interests. Some treat it as a classification identifying some structure of truth and reality that exists whether or not humans recognize it. Others treat it as intrinsically useful to the human mind, but not necessarily reflective of something more objective. Candidates examples of natural kinds are found in all the sciences, but the field of chemistry provides the paradigm example of elements.
Naturalized epistemology is a collection of philosophic views concerned with the theory of knowledge that emphasize the role of natural scientific methods. This shared emphasis on scientific methods of studying knowledge shifts focus to the empirical processes of knowledge acquisition and away from many traditional philosophical questions. There are noteworthy distinctions within naturalized epistemology. Replacement naturalism maintains that traditional epistemology should be abandoned and replaced with the methodologies of the natural sciences. The general thesis of cooperative naturalism is that traditional epistemology can benefit in its inquiry by using the knowledge we have gained from the cognitive sciences. Substantive naturalism focuses on an asserted equality of facts of knowledge and natural facts.
Laurence BonJour is an American philosopher and Emeritus of Philosophy at the University of Washington.
Computational epistemology is a subdiscipline of formal epistemology that studies the intrinsic complexity of inductive problems for ideal and computationally bounded agents. In short, computational epistemology is to induction what recursion theory is to deduction. It has been applied to problems in philosophy of science.
Metaepistemology is the branch of epistemology and metaphilosophy that studies the underlying assumptions made in debates in epistemology, including those concerning the existence and authority of epistemic facts and reasons, the nature and aim of epistemology, and the methodology of epistemology.
Formal epistemology uses formal methods from decision theory, logic, probability theory and computability theory to model and reason about issues of epistemological interest. Work in this area spans several academic fields, including philosophy, computer science, economics, and statistics. The focus of formal epistemology has tended to differ somewhat from that of traditional epistemology, with topics like uncertainty, induction, and belief revision garnering more attention than the analysis of knowledge, skepticism, and issues with justification.
Richard Newell Boyd was an American philosopher, who spent most of his career teaching philosophy at Cornell University where he was Susan Linn Sage Professor of Philosophy and Humane Letters Emeritus. He specialized in epistemology, the philosophy of science, language, and mind.
A priori and a posteriori are Latin phrases used in philosophy to distinguish types of knowledge, justification, or argument by their reliance on experience. A priori knowledge is independent from any experience. Examples include mathematics, tautologies, and deduction from pure reason. A posteriori knowledge depends on empirical evidence. Examples include most fields of science and aspects of personal knowledge.
Epistemology or theory of knowledge is the branch of philosophy concerned with the nature and scope (limitations) of knowledge. It addresses the questions "What is knowledge?", "How is knowledge acquired?", "What do people know?", "How do we know what we know?", and "Why do we know what we know?". Much of the debate in this field has focused on analyzing the nature of knowledge and how it relates to similar notions such as truth, belief, and justification. It also deals with the means of production of knowledge, as well as skepticism about different knowledge claims.
Formative epistemology is a collection of philosophic views concerned with the theory of knowledge that emphasize the role of natural scientific methods. According to formative epistemology, knowledge is gained through the imputation of thoughts from one human being to another in the societal setting. Humans are born without intrinsic knowledge and through their evolutionary and developmental processes gain knowledge from other human beings. Thus, according to formative epistemology, all knowledge is completely subjective and truth does not exist.
In philosophy, naturalism is the idea that only natural laws and forces operate in the universe. In its primary sense it is also known as ontological naturalism, metaphysical naturalism, pure naturalism, philosophical naturalism and antisupernaturalism. "Ontological" refers to ontology, the philosophical study of what exists. Philosophers often treat naturalism as equivalent to materialism.
