The Concept of Defeasibility a. Legal, Moral, and Epistemic The language of defeasibility is not unique to epistemology.
In fact, its use in epistemology is arguably derived from its use in legal and moral discourse. Hart explained that though contracts were comprised of an offer, acceptance and consideration, contracts may still be void or voidable due to some exception such as fraud or incapacity.
In making this application to contracts, Hart noted that there is no specific term in the English language to refer to exceptions to a basic legal rule Hart,p.
The defeasibility of legal rules is analogous to the defeasibility of moral rules in ethics or moral philosophy. While there may be obligations to do X, many ethical theories add that at least some of these obligations are only prima facie duties.
They can be overridden by other factors and thus are no longer morally binding. Moral rules, like legal rules, are subject to being defeated in particular circumstances or under particular conditions. Talk of defeasibility in the legal and moral context translates into epistemic defeasibility in at least one obvious way.
If we think of positive epistemic status as normative, then this status will — like moral and legal rules — be subject to being overridden by other factors.
In circumstance C we may be epistemically justified to believe p, just as Metaphysics epistemology paper essay are legally or morally justified to perform action A in circumstance C.
This is particularly evident in deontological conceptions of epistemic justification, according to which we have various intellectual obligations and certain epistemic principles forbid believing p under certain circumstances, for example when p is not likely to be true or when p is likely to be false.
But even if we think of justification simply in terms of having adequate evidence, justification will be variable. Chisholm, ppfor example, notes that while evidence e may make h evident, another evident proposition, d, may defeat the tendency of e to make h evident because the conjunction of e and d does not make h evident.
In other words, there may be a loss of justification when new evidence is added to an existing evidence base. Basic Distinctions Defeater theories are generally distinguished by how they construe what does the defeating and what gets defeated.
What does the defeating in the second case is a mental state of the cognizer. On the other hand, philosophers who take defeaters to be mental states of the cognizer tend to see them as defeating the justified status of a belief, either by downgrading the degree of justification or by canceling the justified status of the belief altogether.
Of course, if justification to some high degree is necessary for knowledge, defeaters that defeat justification may also prevent a true belief from counting as knowledge.
The Gettier Problem and Propositional Defeaters a. The Tripartite Definition of Knowledge and the Gettier Problem One of the primary tasks of epistemology is the examination of the nature of knowledge.
One aspect of such inquiry is the analysis of those conditions that are severally necessary and jointly sufficient for knowledge. There have been three fairly widespread and long-standing intuitions concerning knowledge in the Western philosophical tradition.
Third, knowledge is not equivalent to true belief. Knowledge has a certain surplus value over true belief. A justified belief is roughly one that has a positive tie or strong connection to the truth goal of believing, something like ".
The so-called traditional or tripartite definition of knowledge as justified true belief expresses all three of the above intuitions. Gettier argued that there are cases in which an individual could plausibly be said to have a true belief that is justified but which fails to constitute knowledge.
However, it seems counterintuitive in this case to suppose that I know that Brown is in Barcelona, even if the belief is true and justified.
One of the early proposals to handle the Gettier Problem involved adding a fourth condition to knowledge that excludes inferences from or dependence on any false beliefs Shope,pp.
But Gettier cases can be generated where there is neither an inference from nor dependence on any false beliefs Steup,pp.
So other strategies must be employed to deal with Gettier counterexamples. One of these strategies employs the concept of defeasibility or defeaters Lehrer and Paxson, ; Swain, ; Shope, Defeasibility Analyses and Propositional Defeaters Defeasibility analyses of knowledge come in a variety of different specific versions.Free metaphysics papers, essays, and research papers.
The Impossibility of Metaphysics - In his work An Inquiry Concerning Human Understanding, Hume outlines the problems inherent to the large body of philosophy he describes as the “accurate and abstract” philosophy, and in particular to metaphysical speculations.

- Metaphysics, Epistemology and Orwell's Since the beginning of recorded time, philosophers have pondered questions of metaphysics (what exists, what is real) and epistemology (how we know what exists and is real, our proof).
Epistemology, the philosophical study of the nature, origin, and limits of human urbanagricultureinitiative.com term is derived from the Greek epistēmē (“knowledge”) and logos (“reason”), and accordingly the field is sometimes referred to as the theory of knowledge.
Epistemology has a long history within Western philosophy, beginning with the ancient Greeks and continuing to the present.
