Empiricism in the philosophy of science, even in its modern variants, takes observation reports of phenomenal states as a reliable route to knowledge. The problem for empiricists is as follows: Why adopt the theory (T1) that observation reports are a reliable way to sort out true from false theories and not adopt the theory (T2) that theories are a reliable way to sort out true from false observation reports? If the empiricist rejects T1 and adopts T2, the empiricist rejects empiricism and becomes a Kantian; however, this does not address the problem, for why should the Kantian adopt T2 and reject T1? The epistemological pendulum swings back.

If a basic statement and theory are incoherent, then observation reports cannot inform us that theories are wrong and theories cannot inform us that observation reports are wrong. Either the theories or observation reports are wrong — or both. Neither T1 nor T2 should be adopted a priori, for they effectively annihilate one another: all we can see is an incoherence between T1 and T2.

Furthermore, even after we recognize an incoherence between an observation report and a theory, this ‘recognizing’ is relative to a given system of logic, background assumptions, language, and cognitive framework: we are even fallible in recognizing incoherence. Whatever method or route we follow that leads to preferring one over the other will either not rest on an Archimedean point, or will not be known to rest on an Archimedean point. All is theory-laden and subject to error. We must admit that it is possible to change the logic we employ, statements we adopt, theories we accept, methods we follow, language we use, or the cognitive frameworks we inhabit, for none of them are privileged.


Rehearsing a Revolution

In bartley, popper on 31/07/2011 at 4:33 am

Here is a copy of the first part of an unfinished biography of Karl Popper, by William W. Bartley: Rehearsing a Revolution [.pdf]. I suggest reading pp. 50-71, for they deal with Popper’s trouble with Kant and Kierkegaard.

Two points of interest I’ve picked up from talking to friends of Bartley: (1) he was either bisexual or gay (this puts his Wittgenstein in a different light); (2) he took up writing the — rather poor, in my opinion — hagiography of Werner Erhard in order to live comfortably in California with his long-time companion.


A Brief Restatement and Defense of Bartley

In bartley, empiricism, experiments on 17/07/2011 at 1:41 am

‘Faith’ is often taken to be a theory that is not taken on logical or empirical grounds. This is little more than a simultaneous disparagement of theories that are not logically or empirically grounded and an assumption that such grounding is possible.

It is impossible, so I conjecture, to ground anything. If this is the case, according to this description of faith, all theories are equally faith-based. That doesn’t seem right. At this point, most people see this as a reductio of the conjecture of the impossibility of grounding. I can intuitively tell apart a scientific theory, they might say, from religious theories. Therefore, some theories are grounded. The nature of grounding is then examined in detail.

The Orthodox Story

In bartley, kuhn, wittgenstein on 03/07/2011 at 12:31 pm

The orthodox story runs as follows: Kuhn is the philosopher that undermined the philosophical tradition of Logical Positivism. I think this is wrong; Kuhn did not manage to break from the preceding philosophical tradition. His work is laden with principles belonging to the philosophy he was determined to reject. In fact, incommensurability, non-directed progress, rejection of the concept of truth as a regulatory principle, and the very thesis of “world change” are all consequences of the positivist elements Kuhn’s philosophy retains.

One intuitively wouldn’t want to have a set of incoherent beliefs. Preferring incoherence is to be frowned upon, for one belief in this set must be false. Any sort of epistemology should then strive for some kind of coherence and mutual support, and if incoherence is found, of finding a way to determine which member of the set is false and which is true.

There are two kinds of coherentism I’m thinking of: the first kind is sort of a nebulous coherentism, that it is better to prefer a set of beliefs that support one another over a set of incoherent beliefs. I would then call myself a ‘weak’ coherentist in a sense, as would most modern epistemologists, but we strive not just for the coherence of our beliefs as indicating its truth, but for the truth of all of our beliefs.

The second kind of coherentism I will call ‘strict coherentism.’ It sees no recourse necessary to any sort of a posteriori examination. This gambit is played, I think, in order to circumnavigate a serious problem for most justificationists: we may be justified in preferring a coherent system over an incoherent system.
