Ancient Greek Skepticism [The Internet Encyclopedia of Philosophy]

Although all skeptics in some way cast doubt on our ability to gain knowledge of the world, the term “skeptic” actually covers a wide range of attitudes and positions. There are skeptical elements in the views of many Greek philosophers, but the term “ancient skeptic” is generally applied either to a member of Plato’s Academy during its skeptical period (c. 273 B.C.E to 1st century B.C.E.) or to a follower of Pyrrho (c. 365 to 270 B.C.E.). Pyrrhonian skepticism flourished from Aenesidemus’ revival (1st century B.C.E.) to Sextus Empiricus, who lived sometime in the 2nd or 3rd centuries C.E. Thus the two main varieties of ancient skepticism: Academic and Pyrrhonian.

Skepticism (Stanford Encyclopedia of Philosophy)

Much of epistemology has arisen either in defense of or in opposition to various forms of skepticism. Indeed, one could classify various theories of knowledge by their responses to skepticism. For example, rationalists could be viewed as skeptical about the possibility of empirical knowledge while not being skeptical with regard to a priori knowledge and empiricists could be seen as skeptical about the possibility of a priori knowledge but not so with regard to empirical knowledge. In addition, many traditional problems, for example the problem of other minds or the problem of our knowledge of God's existence, can be seen as restricted forms of skepticism which hold that we cannot have knowledge of any propositions in some particular domain thought to be within our ken.

  • Even before examining the various general forms of skepticism, it is
    crucial that we distinguish between philosophical skepticism and
    ordinary incredulity because doing so will help to explain why
    philosophical skepticism is so intriguing.
  • The point here is that in this case, and in all ordinary
    cases of incredulity, the grounds for the doubt can, in principle, be
    removed. As Wittgenstein would say, doubt occurs within the context of
    things undoubted. If something is doubted, something else must be held
    fast because doubt presupposes that there are means of removing the
    doubt.[2]
    We doubt that the bird is a robin because,
    at least in part, we think we know how robins typically fly and what
    their typical coloration is. That is, we think our general picture of
    the world is right — or right enough — so that it does
    provide us with both the grounds for doubt and the means for
    potentially removing the doubt. Thus, ordinary incredulity, say about
    some feature of the world, occurs against a background of sequestered
    beliefs about the world. We are not doubting that we have any knowledge
    of the world. Far from it, we are presupposing that we do know some
    things about the world. To quote Wittgenstein, “A doubt without an end
    is not even a doubt” (Wittgenstein 1969, ¶ 625).

Contemporary Skepticism [The Internet Encyclopedia of Philosophy]

  • Philosophical views are typically classed as skeptical when they involve advancing some degree of doubt regarding claims that are elsewhere taken for granted. Varieties of skepticism can be distinguished in two main ways, depending upon the focus and the extent of the doubt.
  • As regards the former, skeptical views typically have an epistemological form, in that they are focused on the epistemic status of certain beliefs. For example, one common variety of skepticism concerns our beliefs about the past and argues that such beliefs lack positive epistemic status – that they are not justified, or are not rational, or cannot constitute knowledge (and perhaps even all three). Where skepticism does not have this epistemological focus, then it tends to be of an ontological form in that it is directed at beliefs about the existence of some supposedly problematic entity, such as the self or God. Here the target of the skepticism is not so much one’s putative knowledge of these entities (though it may be that as well), but rather the claim that they exist at all.


    As regards the latter, one can differentiate between skeptical views that are either local or radical. Local varieties of skepticism will only concern beliefs about a certain specific subject matter, such as beliefs in abstract objects or the conclusions of inductive arguments. Since ontological varieties of skepticism tend to be concerned with the existence of particular sorts of entities, they are usually (though not always) of this local form. In contrast, radical forms of skepticism afflict most of our beliefs and thus pose, at least potentially, the most pressing philosophical challenge.

Five New Rules for the Photoshop Era | Open The Future | Fast Company

If you're annoyed by the "birther" churn, get used it--this kind of political hack is here to stay. It's easy and effective. Cheap digital tools make the work of faking official documents, "candid" images, and behind-the-scenes videos readily possible, even for rough amateurs.

philosophy critical-theory objects speculative-realism realism about(BrunoLatour) science epistemology representation

  • Philosophical epistemology begins from a stark opposition between words (or, alternatively mental representations) on the one hand, and world, on the other hand. Like the King’s soldiers, it then wonders how it is possible to put these two sundered halves together again. It is not difficult to see how it might be possible to cook up a theory of reference for propositions such as “the cat is on the mat”, but what could adequation between word and “thing” possibly mean for propositions like “the savanna is advancing on the jungle” or “the jungle is advancing on the Savannah”? What would a mental representation or mimesis between idea and world be in such a case? What are the inscrutable markers we find in our mental representation that establish such a correspondence? What resemblance is there between this proposition or statement and the world that it depicts? Posed in this way the question seems irresolvable as we either remain a “mind-in-a-vat” with no access to anything save our own mental representations (and therefore without the means of distinguishing the marks of the true from the false in our representations), or, equivalently, a “speaker-in-a-vat” with no means of distinguishing the marks that distinguish the true and the false in our propositions.


    The whole problem, Latour contends, lies in the fact that philosophers always begin too late.

  • The entire problem emerges because philosophy begins with its “knowledge-datum” as it appears at dusk, but does so without being aware that it is doing so. In other words, beginning with the product of knowledge labor as inscribed in a text such as the Principia or the Elements, philosophy then proceeds to inquire into how the propositions that compose this product resemble or mimic true reality such that they are adequate to that reality. As a result it finds itself plunged into irresolvable difficulties because, of course, reality shares no resemblance to either these mental representations or these propositions. In other words, when conceiving knowledge as a mimetic adequation between mind and world, word and world, we very quickly encounter an unsurpassable gap between the two. What possible resemblance is there between a chemical equation and the transformation that takes place in a beaker in the laboratory? The two could not be more unlike.

Less Wrong: Atheism = Untheism + Antitheism

Hunter-gatherer superstition isn't much like what we think of as "religion". Early Westerners often derided it as not really being religion at all, and they were right, in my opinion. In the hunter-gatherer stage the supernatural agents aren't particularly moral, or charged with enforcing any rules; they may be placated with ceremonies, but not worshipped. But above all - they haven't yet split their epistemology. Hunter-gatherer cultures don't have special rules for reasoning about "supernatural" entities, or indeed an explicit distinction between supernatural entities and natural ones; the thunder spirits are just out there in the world, as evidenced by lightning, and the rain dance is supposed to manipulate them - it may not be perfect but it's the best rain dance developed so far, there was that famous time when it worked...

The Analysis of Knowledge (Stanford Encyclopedia of Philosophy)

    • In his short 1963 paper, "Is Justified True Belief Knowledge?",
      Edmund Gettier presented two effective counterexamples to the JTB
      analysis (Gettier 1963). The second of these goes as follows. Suppose
      Smith has good evidence for the false proposition




      1. Jones owns a
        Ford.[5]
      2. Either Jones owns a Ford or Brown is in Boston.
      3. Either Jones owns a Ford or Brown is in Barcelona.
      4. Either Jones owns a Ford or Brown is in Brest-Litovsk.




      Since (1) entails each of the propositions (2) through (4), and since
      Smith recognizes these entailments, he is justified in believing each
      of propositions (2)-(4). Now suppose that, by sheer coincidence, Brown
      is indeed in Barcelona. Given these assumptions, we may say that
      Smith, when he believes (3), holds a justified true belief. However,
      is Smith's belief an instance of knowledge? Since Smith has no
      evidence whatever as to Brown's whereabouts, and so believes what is
      true only because of luck, the answer would have to be
      ‘no’. Consequently, the three conditions of the JTB
      account — truth, belief, and justification — are not
      sufficient for
      knowledge.[6]
      How must the analysis of knowledge be modified to make it immune to
      cases like the one we just considered? This is what is commonly
      referred to as the "Gettier problem".

Abstract Objects (Stanford Encyclopedia of Philosophy)

It is widely supposed that every object falls into one of two categories: Some things are concrete; the rest abstract. The distinction is supposed to be of fundamental significance for metaphysics and epistemology. The present article surveys a number of recent attempts to say how it should be drawn.

Guest Post: Marcelo Gleiser on How do We Know? | Cosmic Variance | Discover Magazine

Given this mechanism, there is a risk that unexpected phenomena, not predicted by any current theory and hence not included in the subset of collisions deemed interesting, will be eliminated by the data filtering process. In this case, and in a paradoxical way, the theories that we construct to amplify our view of physical reality will actually limit what we can know about nature.

Half an Hour: The New Nature of Knowledge

    • What is important is not who came up with the theory (because we know that what I will say is that the theory is emergent from the works of numerous writers) but rather what the salient points are of the theory. From the work just cited, we can identify three major points (and those who care to look will find those points repeated throughout my own writing):

      1. knowledge is not an object, but a series of flows; it is a process, not a product
      2. it is produced not in the minds of people but in the interactions between people
      3. the idea of acquiring knowledge, as a series of truths, is obsolete
    • These point to a conception of knowledge dramatically from the Cartesian foundation or the Platonic form, a conception of knowledge that challenges even the Aristotlean categpry and the Newtonian law of nature. In particular, what seems to me to be relevant, is that the knowledge thus produced is:
      1. non-propositional, that is, not sharp, definite, precise, expressible in language
      2. non-discrete, that is, not located in any given place or instantiated in any particular form
      3. non-objective, that is, independent of any given perspective, point of view, or experience

Engine and Caboose, On the Same Track « Easily Distracted

commentary politics rhetoric argument howto conservative conservatism epistemology humility

  • 1) If you want to argue that governmental or institutional action has unforeseen and perverse consequences, you have to apply that insight retroactively, with rigor. Meaning, among other things, that the economic crisis of the moment from this perspective is just as much an unexpected consequence of earlier governmental actions, in this case, changes in regulatory regimes, in monetary policy, and so on, under the Bush and Clinton Administrations.


    Moreover, if you want to add intellectually to that composite body of thought rather than apply it in a dull fashion, one of the possibilities to consider is that some of those thinkers on Brooks’ list were too fixated on the state as the only large institutional force in modern life whose actions can lead to unforeseen or perverse consequences. Civil institutions and large corporations ought to be looked at in the same manner, with the same skeptical eye, with the same understanding of social causality. What have companies been doing to the fabric of everyday life in America over the last two decades? What kinds of top-down changes have they imposed on people, with perverse consequences?

  • 2) Following from this: so what kind of planning or action is allowable under the banner which Brooks hoists in the first part of his column? That’s where some kind of interesting forward-looking argument could begin. Not this kind of “well, maybe limited conservative views of government will turn out to be right, rather than this OMFG CRAZY LIBERAL stuff”. There is no such thing as a limited conservative philosophy of government or official action in the United States at the moment if by that you are looking to party politics. No movement, no party, nothing that Brooks can point to and say, “There, that’s it, that’s what I mean, that’s how someone who believes in Oakeshott-Burke-Orwell-Hayek makes policy”. Unless what Brooks means is party libertarianism in the U.S., which is not really what anybody on Brooks’ list of thinkers believed in except arguably for Hayek.
