Philosophy epistemology

If it is replied that the concept of red and others like it are acquired when we are taught the word red in childhood, a similar difficulty arises.

They might say instead that they thought they knew or that they felt sure, but they cannot rationally continue to insist that they knew if what they claimed to know turns out to be false. Rather, there must be some positive support relationship — for instance, some sort of explanatory relationship — between the members of a coherent set in order for the beliefs to be individually justified.

Accordingly, it is common for proponents of such views to hold that if A knows that p, A must be conscious of what A knows.

To put it another way, the justification condition was meant to ensure that knowledge was based on solid evidence rather than on luck or misinformation, but Gettier-type examples seem to show that justified true belief can still involve luck and thus fall short of knowledge.

Infinitism typically takes the infinite series to be merely potential, and an individual need only have the ability to bring forth the relevant reasons when the need arises. To a considerable extent, skepticism is born of such reflection.

Logical propositions are often a priori, always necessary, and typically analytic. Alvin Goldman writes in his Causal Theory of Knowing that for knowledge to truly exist there must be a causal chain between the proposition and the belief of that proposition. Rationalists hold that human beings have knowledge that is prior to experience and yet significant.

Tautological propositions are generally a priori, necessary, and analytic, and significant propositions are generally a posteriori, contingent, and synthetic. Epistemologists argue over whether belief is the proper truth-bearer.

For instance, I believe that my car is parked where I left it this morning, even though I am not currently looking at it.

But why should reason be accepted as infallible. Skepticism begins with the apparent impossibility of completing this infinite chain of reasoning, and argues that, ultimately, no beliefs are justified and therefore no one really knows anything. PUN has always been true in the past.

Perception, reason, memory, testimony, introspection and innate ideas are all supposed sources of knowledge. The argument notes that some of our perceptions are inaccurate. Jain philosophy attempts to explain the rationale of being and existence, the nature of the Universe and its constituents, the nature of bondage and the means to achieve liberation.

Price —and Bertrand Russell —each of whom considered whether there are ways of apprehending the world that do not depend on any form of inference and, if so, what that apprehension consists of see below Perception and knowledge.

In other words, people know what it means to say that a and b are equal, no matter what a and b are. While justification seems, at first glance, to be a matter of a belief's being based on evidence and reasoning rather than on luck or misinformation, we shall see that there is much disagreement regarding how to spell out the details.

Descartes' Epistemology

The "generality problem" notes that some of these descriptions might specify a reliable process but others might specify an unreliable process, so that we cannot know whether a belief is justified or unjustified unless we know the appropriate level of generality to use in describing the process.

This example and others like it, while perhaps somewhat far-fetched, seem to show that it is possible for justified true belief to fail to constitute knowledge.

Descartes' Epistemology

Epistemology is the investigation of the nature of knowledge itself. Its study focuses on our means for acquiring knowledge and how we can differentiate between truth and falsehood. Modern epistemology generally involves a debate between rationalism and empiricism.

Rationalists believe that. A thorough epistemology should, of course, address all kinds of knowledge, although there might be different standards for a priori and a posteriori knowledge.

We can also distinguish between individual knowledge and collective knowledge. Dec 03,  · René Descartes (–) is widely regarded as the father of modern philosophy. His noteworthy contributions extend to mathematics and physics.


May 02,  · Ontology and epistemology are both important elements of the philosophy of knowledge. If they often overlap, they have clear distinction: epistemology is about the way we know things when ontology is about what things are.

Epistemology is. Metaphysical philosophy has birthed formal sciences such as logic, mathematics and philosophy of science, but still includes epistemology, cosmology and others.


Philosophical progress Many philosophical debates. Philosophy & Technology addresses such challenges, in order to improve our critical understanding of the conceptual nature and practical consequences of technologies, and hence provide the conceptual foundations for their fruitful and sustainable developments.
