i am an unapologetic popperian, but i thoroughly enjoyed reading professor haack' s article. my only complaints are that (1) she too lightly dismisses or devalues the demarcation problem, (2) overstates the extent to which popper' s philosophy of science is inconsistent with
competitor
theories, such as kuhn' s, and (3) clings to the most radical version of falsificationism that popper himself did not follow in his everyday life (recognizing the difference between high theory and everyday life) .
in this article, we will first examine hume’s own argument, provide a reconstruction of it, and then survey different responses to the problem which it poses .

the description of concepts as' open - ended' does appear to be the philosopher' s stone which popper sought but never found. he correctly saw that there is a problem with most people' s idea of certainty, yet never quite fought his way through to an acceptable solution .
popper offered two methods of comparing theories in terms of verisimilitude, the qualitative and quantitative definitions. on the qualitative account, popper asserted :
finally, it is crucial to remember that popper' s entire approach to metaphysics and epistemology was motivated by his belief that the human endeavor is to solve problems, both theoretical and practical. to that end, he put great stock in real science (over what he and the logical positivists called
psuedo - science
). viewed in this light, popper' s falsification criterion is perhaps less radical than professor haack supposes (even if it is more radical than many others presume). for anyone who agrees with popper about the basic human endeavor, the demarcation problem remains of great importance, even if it is problematic and not completely resolved by popper' s falsification criterion .
hume, whom popper called
one of the most rational minds of all ages
[ pkp2 1019 ], is renowned for elaborating the' problem of induction' - a supposedly logical proof that generalisations from observation are invalid. most later philosophers have accepted hume' s arguments, and libraries have been filled with attempts to solve his' problem.'

thomas samuel kuhn was born on july 18, 1922, in cincinnati, ohio, united states. he received a ph. d. in physics from harvard university in 1949 and remained there as an assistant professor of general education and history of science. in 1956, kuhn accepted a post at the university of california - - berkeley, where in 1961 he became a full professor of history of science. in 1964, he was named m. taylor pyne professor of philosophy and history of science at princeton university. in 1979 he returned to boston, this time to the massachusetts institute of technology as professor of philosophy and history of science. in 1983 he was named laurence s. rockefeller professor of philosophy at mit .
this paper is not the first to subject popper' s critical rationalism to detailed criticism. p. a. schilpp' s the philosophy of karl popper contains several less than sympathetic essays, as does anthony o' hear' s karl popper: philosophy and problems. and of course o' hear earlier devoted a whole book to the matter. other writers have been led to outright rejection. when the logic of scientific discovery first appeared, popper' s famous contemporary hans reichenbach asserted bluntly :
the results of this book appear to me completely untenable... i cannot understand how popper could possibly believe that with respect to the problem of induction his investigations mean even the slightest advance .

however, in the 1970s a series of papers published by researchers such as miller, tichý, and grünbaum in particular revealed fundamental defects in popper’s formal definitions of verisimilitude. the significance of this work was that verisimilitude is largely important in popper’s system because of its application to theories which are known to be false. in this connection, popper had written :

it' s clear from the outset that, in contrast to me, professor haack is not a fan of popper' s philosophy. she even takes a few digs at his famously curmudgeonly character, and his alleged unwillingness to learn from others (which is belied by his numerous positive references to works by other philosophers, including for example alfred tarski and gilbert ryle). nevertheless, professor haack is quite right that popper' s philosophy of science is: (a) more radical than readers commonly accept; (b) not as clearly specified (across the body of popper' s work) as some readers, including the supreme court, would have us believe; and (c) not a very useful basis for determining the admissibility of scientific evidence in court .
hume’s purpose is clearly not to argue that we should not make inductive inferences in everyday life, and indeed his whole method and system of describing the mind in naturalistic terms depends on inductive inferences through and through. the problem of induction then must be seen as a problem that arises only at the level of philosophical reflection .

popper' s kantian premise thus deprives cr of universality. since it is ultimately the product of the pre - programmed interpretation of the data which entered popper' s mind, cr is a theory which can only be applied to popper. according to his own view of his contact with reality, he would not be able to verify the relevance of cr to anybody else .

the conclusion then is that our tendency to project past regularities into the future is not underpinned by reason. the problem of induction is to find a way to avoid this conclusion, despite hume’s argument .

cr claims to distinguish science from non - science by the refutability of scientific theories. popper' s standard example was newtonian physics, so radically displaced by einstein. 23 on the other hand, popper maintained, there were theories such as those of marx and freud, which were non - science because irrefutable. this was popper' s famous' criterion of demarcation,' which he developed as a young man and held to all his life .

popper' s platonism
( o' hear, p. 181) and j. w. n. watkins :
popper' s objectivism is a very mitigated version of platonism
[ pkp1 399 ]. however, both would have agreed with feigl and meehl that for plato' ideas' exist extra to mankind; whereas, for popper, objective knowledge is man - made [ pkp1 543 ]. popper may have been led to idealism by his scepticism - an ancient pattern. o' hear concludes his study :
having torn ideas from their living context, popper was led both to his radical scepticism and to his postulation of an abstract world of ideas…

to this i should like to say that i am not aware of the fact that professor ryle has ever held what i call' the two languages theory'. how could he, believing as he does that the problem arises out of category - mistakes within the one natural language? it is not to him i was alluding in that place .
first, there seems little conjectural about the theory of worlds 1, 2, & 3. in none of popper' s several presentations is the theory offered as an hypothesis. rather, it is laid out as a discovery, as what popper thought the facts to be .
to conclude under this head, it is plain - even after only a very brief treatment - that popper' s kantian premise, far from providing cr with a secure footing, leads instead to insuperable problems, not least of which are conflicts with popper' s own rejection of determinism and subjectivism in such works as the poverty of historicism and the open universe .

hume’s argument has been presented and formulated in many different versions. there is also an ongoing lively discussion over the historical interpretation of what hume himself intended by the argument. it is therefore difficult to provide an unequivocal and uncontroversial reconstruction of hume’s argument. nonetheless, for the purposes of organizing the different responses to hume’s problem that will be discussed in this article, the following reconstruction will serve as a useful starting point .

the main objection to all these views is that they do not really solve the problem of induction in a way that adequately secures the pillars on which inductive inference stands. as salmon puts it, “admission of unjustified and unjustifiable postulates to deal with the problem is tantamount to making scientific method a matter of faith” (salmon 1966: 48) .
now i agree with every word of this but i completely fail to see its relevance: in focusing attention upon one statement, professor sellars, understandably enough, got its context out of focus .

there are only two kinds of arguments: demonstrative and probable (hume’s fork) .
what will then be the consequence of supposing that hume’s problem should indeed have been a regress, rather than a circularity? here different opinions are possible. on the one hand, one might think that a regress still leads to a skeptical conclusion. so although the exact form in which hume stated his problem was not correct, the conclusion is not substantially different (sober 1988). another possibility is that the transformation mitigates or even removes the skeptical problem. for example, norton argues that the upshot is a dissolution of the problem of induction, since the regress of justifications benignly terminates (norton 2003). and okasha more mildly suggests that even if the regress is infinite, “perhaps infinite regresses are less bad than vicious circles after all” (okasha 2005b: 253) .
schurz’s theorems on the optimality of wmi apply to the case where there are finitely many predictive methods. one point of discussion is whether this amounts to an important limitation on its claims to provide a full solution of the problem of induction (eckhardt 2010) .

popper, 'content' and 'degree of confirmation': a reply to dr. bar - hillel
so no hard core, no difference of opinion as far as i can see, underlies professor sellars' first lump - - although i seem to differ with him about the relevance of his comments .
hume’s argument is one of the most famous in philosophy. a number of philosophers have attempted solutions to the problem, but a significant number have embraced his conclusion that it is insoluble. there is also a wide spectrum of opinion on the significance of the problem. some have argued that hume’s argument does not establish any far - reaching skeptical conclusion, either because it was never intended to, or because the argument is in some way misformulated. yet many have regarded it as one of the most profound philosophical challenges imaginable since it seems to call into question the justification of one of the most fundamental ways in which we form knowledge. bertrand russell, for example, expressed the view that if hume’s problem cannot be solved, “there is no intellectual difference between sanity and insanity” (russell 1946: 699) .
popper' s solution was certainly correct in one respect. the problem of induction would indeed vanish if there were no such thing as induction. however, the issue would be resolved much more positively were it to turn out that hume had been wrong, and that there never had been any problem with induction in the first place. and, in point of fact, this is the case. despite his great skill as a thinker and writer, hume missed the point. induction does not depend for its validity on observation, but on the law of identity .

formal learning theory can be regarded as a kind of extension of the reichenbachian programme. it does not offer justifications for inductive inferences, in the sense of giving reasons why they should be taken as likely to produce a true conclusion. rather it offers reasons for following particular methods based on their optimality in achieving certain desirable epistemic ends, even if there is no guarantee that at any given stage of inquiry the results they produce are at all close to the truth. recently, however, steel (2010) has suggested that formal learning theory offers more, and does provide a solution to the problem of induction. this claim is based on a rather restrictive interpretation of “hume’s problem” as the problem: “what is the justification for making inductive generalizations at all? ” (2010: 182), rather than as the problem of giving the grounds for a given inductive inference. steel’s claims have been disputed by colin howson (2011) .
as a footnote here, it may be recorded that popper was not renowned for living up to his philosophy in his professional life. his obituary in the times recorded his reputation as
a difficult man .
the daily telegraph commented ,
popper' s belief in his own infallibility was remarkable .
40 later, the times magazine reported that popper' s students at the london school of economics found him so intolerant of criticism that they used to joke about
the open society, by one of its enemies .
41
. thus i should be inclined (not more than this) to entertain the opposite conclusion to the one drawn by professor ryle although, admittedly, the premises would be insufficient for a formal derivation of the conclusion .

there is besides the singularly popperian problem of marxism. marxism was one of the theories which led popper to develop his conception of demarcation in the first place :
i had been shocked by the fact that the marxists... were able to interpret any conceivable event as a verification of their theories
[ unq 41 - 2 ]. yet in
replies to my critics
popper changed his tune :
marxism was once a scientific theory
;
marxism was once a science
[ pkp2 984 - 5 ]. no doubt popper would have swamped this objection with distinctions between marx and marxism, 24 but the notion that marxism could both be and not be a science does little to inspire confidence in popper' s theory of demarcation .
one option here is to think that the significance of the problem of induction is somehow restricted to a skeptical context. hume himself seems to have thought along these lines. for instance he says :
after presenting the problem, hume does present his own “solution” to the doubts he has raised (e. 5, t. 1. 3. 7–16). this consists of an explanation of what the inductive inferences are driven by, if not reason. in the treatise hume raises the problem of induction in an explicitly contrastive way. he asks whether the transition involved in the inference is produced
second, professor haack (in common with many others, including perhaps kuhn himself) is too quick to conclude that thomas kuhn' s theory of scientific revolutions is inconsistent with popperian falsificationism. popper and kuhn both believed that scientific theories are based on certain axioms, which could prove false, and always contingent. moreover, despite kuhn' s criticisms of popper and falsification, his own theory of anomalies (discrepancies between theories and observed facts) seems to depend on falsification for the erosion of the existing paradigm prior to its replacement by a new paradigm. kuhn was not nearly the scientific relativist that he is often made out to be. in chapter xiii of the
at the same time, it is perfectly true that i had professor ryle in mind when, in another paragraph of my paper, i tried to chow briefly that the theory of' category - mistakes' is also untenable .

now i agree with professor popper that the two - language theory of the 1930' s, which continued, as he points out, the tradition of neutral monism ,
is no longer tenable
. i also agree that
the idea of a mutual translatability
of - - shall we say - - mind talk and behaviour talk
had to be given up long since
, in spite of ryle' s valiant efforts to the contrary. i do not agree, however, that
with it the two - language solution disappears

kuhn also took issue with karl popper' s view of theory - testing through falsification. according to kuhn, it is the incompleteness and imperfection of the existing data - theory fit that define the puzzles that characterize normal science. if, as popper suggested, failure to fit were grounds for theory rejection, all theories would be rejected at all times .

a critical attitude, particularly a self - critical one, is also every bit as important in philosophy as popper thought it was, even if he did not always exercise his own. subjecting one' s pet theories to the kind of penetrating analysis popper was so good at is the healthiest mental activity one can undertake. conviction is much easier to come by than rectitude and we must always be on guard against
cocksureness
- as popper so rightly warned us [ ose2 387 ] .
popper built his philosophy on foundations borrowed from hume and kant. his first premise was wholehearted acceptance of hume' s attack on induction. the second, to be addressed in the next section, was agreement with kant' s view that it is our ideas which give form to reality, not reality which gives form to our ideas .

popper' s problem was of course that the theory of evolution is just about as inductive as one can get, yet he wanted us to believe that induction is a myth. he found no way out of this impasse, and in the end decided that the only solution was to evade the issue :
i have come to the conclusion that darwinism is not a testable scientific theory, but a metaphysical research programme

how then does the deductive procedure work? popper specifies four steps (logic of scientific discovery, 1. 3, 9) :

it is also hard to accept that popper' s opinion of marx had not been very high. when someone writes, for example, that marx' s theory of surplus value was
brilliant
and
a theoretical success of the first order
[ ose2 172 - 3 ]; that marx' s exploitation theory
deserves the greatest respect
[ ose2 178 ]; and that marx made
serious and most important contributions to social science
[ ose2 253 ]; it does not look as though the writer' s opinion is' deteriorating.'

it is thus surprising to discover that popper himself hardly lived up to this ideal of non contradiction. when one examines critical rationalism, for example, one soon notices that it is based on questionable premises; that its internal logic is seriously flawed; that it is inconsistent with other elements of popper' s thought; and that it leads to conflicts with his own publicly stated convictions .

this is a fallacy of reasoning, for p might occur for reasons other than a. however, popper pointed out that the following reasoning
one of the first and most important methods for tackling the “inverse” problem using probabilities was developed by thomas bayes. bayes’s essay containing the main results was published after his death in 1764 (bayes 1764). however, it is possible that the work was done significantly earlier and was in fact written in direct response to the publication of hume’s enquiry in 1748 (see zabell 1989: 290–93, for discussion of what is known about the history) .
leaving aside the problem of how' physically real possibilities' fit into the category of conjectural knowledge, popperian' propensity' appears so similar to aristotelian' potentiality' -
all movement or change means the realisation (or' actualisation') of some of the potentialities inherent in the essence of a thing
[ ose2 6 ] - that, in fairness, one must note that popper dismissed aristotle' s ideas about potentiality as
pretentious jargon
[ ose2 7 ] .
here, verisimilitude is defined in terms of subclass relationships: \ (t _ 2 \) has a higher level of verisimilitude than \ (t _ 1 \) if and only if their truth - and falsity - contents are comparable through subclass relationships, and either (a) \ (t _ 2 \) ’s truth - content includes \ (t _ 1 \) ’s and \ (t _ 2 \) ’s falsity - content, if it exists, is included in, or is the same as, \ (t _ 1 \) ’s, \ (or \) (b) \ (t _ 2 \) ’s truth - content includes or is the same as \ (t _ 1 \) ’s and \ (t _ 2 \) ’s falsity - content, if it exists, is included in \ (t _ 1 \) ’s .
the key feature of popper' s theory exemplified by the modus tolens argument is
critical testing
. in order for critical testing to give valid results, the theory to be tested must be free from any
looseness
; popper lists four criteria, or levels of evaluating, for determining whether a proposed theory is sufficiently
tight
to be admitted as a
scientific
theory .
some authors have argued that in fact s does not rely on any premise or even presupposition that would require us to already know the conclusion of x. s is then not a “premise circular” argument. rather, they claim, it is “rule - circular”—it relies on a rule of inference in order to reach the conclusion that that very rule is reliable. suppose we adopt the rule r which says that when it is observed that most f s are g s, we should infer that most f s are g s. then inference x relies on rule r. we want to show that rule r is reliable. we could appeal to the fact that r worked in the past, and so, by an inductive argument, it will also work in the future. call this argument s * :
if, however, i have somewhere' tacitly' and unconsciously added the l premise which professor sellars says i have added (i cannot detect any trace of it) then i wish. again, to recant. for i am in complete agreement with professor sellars' thesis that if a statement a says that another statement e is about something, then a usually does not, to use professor sellars' words play' the same sort of a role as
the moon is round
'. a need not be, and usually is not,' descriptive' in the same sense as the statement about the moon (although it may be:' what has your last lecture about?' - -' it was a lecture about probability', is an instance of descriptive usage) .
relatively few philosophers have embraced it however. tom settle, a major contributor to p. a. schilpp' s massive festschrift, the philosophy of karl popper, stated firmly in 1970 :
as a criterion of demarcation between science and nonscience, popper' s' falsifiability' - plus - a - critical - policy does not work
[ pkp2 719 ]. other contributors evidently agreed; among them a. j. ayer, william c. kneale, imre lakatos, grover maxwell, and hilary putnam .
again, the problem is that i may indeed be happy, but for reasons other than having won the lottery; for example, i may not have won the lottery, but still be happy because i did well at my studies .
further, remembering popper' s humian premise, one immediately wants to ask: if we are not allowed to argue from positive instances to true laws, why are we allowed to argue from counterinstances to negative laws (we were told above that
natural laws... deny
). the reasoning process is the same. collecting disconfirmations and arguing negatively scarcely differs from collecting confirmations and arguing positively. both are inductive procedures and, as such, have been disallowed in advance by popper' s rejection of induction .
47. since this paper rejects cr on logical grounds, it has not been thought necessary to discuss cr' s buttress concepts:' degrees of testability,'' corroboration,'' verisimilitude,' etc. these are analyzed in o' hear, karl popper, ch. 3, and defended by david miller, critical rationalism, ch. 10 and passim. for accounts of popper' s ethics and politics, see tangled web, op cit. , pp. 24 - 26 & 29 - 30 .
unfortunately, neither the lines quoted, nor the rest of the passage in the book, clarify the meaning of the word' fact.' since popper' s claim that' truth means correspondence to the facts' cannot be evaluated without such clarification, we turn again to chambers dictionary, which defines' fact' as
reality, a real state of things, as distinguished from a mere statement or belief .
but if this definition is correct, it leads immediately to another problem with cr .

nonetheless, although this paper rejects popper' s main theses, it should not be construed to imply that study of his work is valueless. far from it. popper wrote well and clearly, and books such as the open society and its enemies, the poverty of historicism and the open universe, while flawed or incomplete, are full of valuable insights, astute observations, and stimulating, sometimes inspiring, prose .
4. e. freeman and h. skolimowski noted that peirce anticipated some of popper' s central ideas [ pkp1 464ff ]. popper acknowledged this [ pkp2 1072 ] though he did not read peirce until the 1950s. he added ,
i feel proud of so eminent a predecessor
[ pkp2 1119 ]. the author is indebted to david conway for pointing out that peirce coined the word' fallibilism.'

popper was evidently aware of this problem. he once wrote about the
realisation
of the
conjecture
of an atomic bomb [ tsib 47 ]. but if a conjecture is realised it is very difficult to see how it remains a conjecture. one might fairly retort, rather, that this one admission blows apart the notion of demarcation by refutability and the whole of cr along with it .

box, i’d better conceal this sticky bun by placing it precariously on the edge of this – the painting on the professor’s side of the “wonderwall” is a colorization of “the passing of arthur” [ black and white illustration ] by florence harrison from tennyson’s “guinevere and other poems”. london: blackie & son, [ 1912 ]. the original illustration has the caption “morte d’arthur”; it is not to be confused with the color illustration with the same title, done by the same artist for the same book. see team, the wonderwall restoration .

one way to put this point is to say that hume’s argument rests on a quantifier shift fallacy (sober 1988; okasha 2005a). hume says that there exists a general presupposition for all inductive inferences, whereas he should have said that for each inductive inference, there is some presupposition. different inductive inferences then rest on different empirical presuppositions, and the problem of circularity is evaded .
this paper will therefore conclude by conjecturing that when popper said ,
in science there is no' knowledge'... in the sense which implies finality
[ ose2 12 ] what he may have been after was rand' s insight that concepts are open - ended. 50
15. popper' s notion of innate cerebral content is deeply problematic but space permits no discussion. for details, see okn 26 - 7, 63, 71 - 2, 258; c & r 27, 47 - 8; tsib 116, & awp 37, 46 .
to fully understand popper' s point of view, some basics of what is known as sentential logic is needed. we are especially interested in this context with the logic of implication - - statements involving
if
and
then
. some preliminary definitions of terminology are required :
the first problem is the method' s apparent arbitrariness. the conjecture or theory to be tested - and popper said the bolder the better - would presumably be selected by the tester. but no criterion for selection is given. 22 we might be referred to an earlier cr exercise, but since that route risks infinite regress (via earlier and earlier cr exercises), the conjecture to be tested must fall outside the scope of cr. therefore, unless further information is provided, it is not obvious how the charge of arbitrariness can be resisted .
further, when thoughts have been objectified as world 3 artefacts, it is not apparent how they accord with popper' s rejection of definitions. once cr is part of an objective world 3, then either the words' critical rationalism' correspond to the world 3 fact that there is such a scientific method, or they do not. we have a genus (scientific methods) and a species (popper' s method) whose differentia is the process of conjecture and refutation. calling popper' s method syllogistic, or dialectical, would be manifestly wrong. thus it would be perfectly in order, not a' tiresome quibble,' to argue about the definition of cr with anyone who maintained, say, that conjecture and refutation was merely logical positivism in disguise. their assertion would be untrue; it would not correspond to the objective, world 3 facts .
