3 One may doubt whether Marx’s ideas were the ‘ruling ideas’ in ‘formerly existing socialism’ in anything more than name (see subsection VII.3, below).

4 The context here suggests that ‘ideological’ has a neutral, descriptive sense rather than Marx’s usual pejorative one; see section II.

6 A theory might be nonideological in this sense, i.e. uncaused by noncognitive social interests or positions, while belief in it is nonetheless thus ideological. A lonely genius might produce an idea for sheer love of truth, which is later taken up when social interests make it convenient. But that there may be nonideological scientific theories is no help if we cannot be justified in accepting them. The distinction is therefore practically irrelevant and I will use ‘belief in X’ and ‘X’ interchangeably.

10 That is, I read Marx as a ‘historical reliabilist’ who grounds justification in a certain sort of causal etiology. I hasten to add that Marx does not offer, and is not interested in, an ‘analysis’ of knowledge or justified belief, in the sense of providing necessary and sufficient conditions for’s knows that (or has justified belief in) p,’ the quest for which has motivated the development of much contemporary reliabilist epistemology.

12 Ideology need not arise because it is in some groups’ interests that it prevail; but it may arise because of those interests. Jon Elster notes that just because a belief is caused by social interest is no reason to suppose that it necessarily serves those interests (’Belief, Bias, and Ideology,’ in Hollis, Martin and Lukes, Steven eds., Rationality and Relativism [Cambridge, MA: MIT Press 1982]123-48Google Scholar). Ideology may also derive from positional factors as well as interest.

13 Marx’s failure to mention this here may be due to the assumption of his controversial thesis that state (including military) activities have an economic explanation, i.e. are ‘superstructural’ phenomena ‘determined’ (bestimmt) by the ‘economic basis’ (CW, 29, 263). On that thesis, the reliability of knowledge acquired due to capitalist state interests in military power then ultimately depends on capitalist interest in profit. This is a charitable reading. Most probably Marx failed to mention the connection here because Capital is primarily concerned with the economic basis; he was not thinking about the superstructure when he wrote these passages.

15 One need not be a Marxist to see the point. Thomas Hobbes, to take someone at the furthest remove from Marx in everything but genius, says, ‘For I doubt not, but if it had been contrary to any man’s right of dominion, or to the interest of men that have dominion, that the three angles of a triangle, should have been equal to the two angles of a square; that this doctrine should have been, if not disputed, yet by the burning of all books of geometry suppressed, as far as he whom it concerned was able’ (Leviathan, Oakeshotte, Michael ed. [New York: Collier 1962], 84Google Scholar).

16 Marx excludes science from this catalogue of ideology, which he contrasts with ‘real positive science’ (CW, 5, 37). Why he thinks he can do this is the subject of this paper.

17 The same is true of Galileo’s prosecutor Cardinal Bellarmine, whose rejection of Copernicanism cannot be attributed either to mere cynicism or self-deception caused, in any simple way, by his interests as a high Church functionary.

18 The dependence of science on funding and institutional support provided by capitalists and the state for their own interests may be sufficient to raise the worry. If we accept Mill’s idea that, given human fallibility, vigorous competition among competing views is necessary for reliability, the influence of practical ends exerted through funding agencies and the like may sometimes reduce competition in the marketplace of ideas below the minimum required for confidence in the outcome. See Mill, John Stuart On Liberty, Rapaport, Elizabeth ed. (Indianapolis: Hackett 1978)Google Scholar. This may be right, but it is not Marx’s concern. In the case of natural science Marx’s reply to the different worry he addresses suggests a way to handle this problem as well.

20 Marx may have been influenced by Hegel’s discussion of work. Hegel says that the servant is forced to labor and thus to confront ‘the independence of the thing,’ the external object on which he works. The master merely consumes the products of this labor and is thus not forced to confront the world; he needs to learn neither what the servant learns about the world nor about himself in transforming it (Hegel, G.W.F. Hegel’s Phenomenology of Spirit, Miller, A.V. trans. [Oxford: Clarendon 1977], 115-19Google Scholar). As I read Hegel, this story incorporates reliabilism about knowledge and the idea that the servant’s standpoint is episternically privileged with regard to the external world and the self.

21 The Eleventh Thesis has other, more obvious meanings as well, including an implicit criticism of the political quietism urged by Hegel, (Hegel’s Philosophy of Right, Knox, T.M. trans. [Oxford: Oxford University Press 1952], 12-13CrossRefGoogle Scholar). But given the epistemological content of the other Theses, the proposed reading is a reasonable if incomplete gloss.

22 Kolakowski, Leszeck ‘Karl Marx and the Classical Definition of Truth,’ in Towards a Marxist Humanism, Peel, Jane Z. trans. (New York: Grove 1968) 38-66Google Scholar. Calling (5)-(7) ‘pragmatic’ will seem misleading if, like Kolakowski, we suppose that pragmatists run things the other way, making practical success constitutive of truth rather than evidence for it. But they need not do so. That is part of the point of this paper. My reading is pragmatist in giving epistemic priority to practical action; Kolakowski’s picks up on the collapse of truth into practical success found in some classical pragmatists, such as James.

23 I take the talk of ‘mirroring’ and ‘reflection’ as metaphorical ways of asserting some version of a classical correspondence theory of truth and not as committing Marx to a ‘reflection theory’ as articulated, for example, by Lenin, (Materialism and Empirio-Criticism, Fineberg, Abraham trans. [Moscow: Progress Publishers 1962]Google Scholar). Unlike Lenin, Marx shows no signs of interest in working out a theory of truth. On the principle of imposing minimal constructions on his statements, he is best read as operating with the prereflective idea that true statements correspond to reality.

24 Lukács criticizes Engels for misreading Kant and more deeply for claiming that noncognitively driven scientific practice reveals anything about the world. Lukács maintains that natural science is not ‘praxis in the dialectical, philosophical sense,’ which means something like the self-conscious activity of which, Lukács supposes, the proletariat alone is capable. Rather it is a sort of Feuerbachian pure contemplation, doubly inadequate to discovery of truths because of scientific use of abstraction, experimental controls, and abstract mathematics, and because this use occurs, in capitalism, under the blind incentive of the market (History and Class Consciousness, Livingston, Rodney trans. [Cambridge, MA: MIT Press 1971], 131-3Google Scholar). He says nothing about natural science under socialism. I mention his view here only to indicate that whatever it amounts to it is not what Engels or I take Marx to mean.

25 This vulgarization found a murderous apogee in the Stalinist thesis of the ‘two world views; promulgated by Stalin’s ideological henchman Andrei Zhadnov in the late 1940s (see Löwy, Michael ‘Stalinist Ideology and Science; in Ali, Tariq ed., The Stalinist Legacy [Boulder, CO: Lynne Rienner 1984] 168-84Google Scholar; Wetter, Gustav Dialectical Materialism, Heath, Peter trans. [London: Routledge and Kegan Paul 1958]Google Scholar). For this crude and preposterous theory, all beliefs, including scientific beliefs, are either ‘bourgeois’ or ‘proletarian’; the former are to be proscribed and the latter promoted by state authority, which replaced scientific norms in several fields, notably biology. See Graham, Loren R. Science, Philosophy, and Human Behavior in the Soviet Union (New York: Columbia University Press 1987Google Scholar). The catastrophic consequences of Lysenkoism for Soviet agriculture are further support for Marx’s views as I read them.

29 Alchemy and scholasticism had selection criteria for practitioners and standards for forming beliefs and norms. But since (Marx would say) there was literally nothing to their subject matters, they lacked real objects which could provide corrective causal feedback. Their selection criteria and epistemic standards were therefore insulated from the sort of correction Marx has in mind for science.

30 This claim must be modified (see section II) where uncomfortable results, e.g., environmental consequences, of the capitalist subjection of nature cause ideological beliefs. Some feminist writers argue, more generally, that an interest in subjugating nature is patriarchal and distorting of aspects of nature which are best revealed by another approach (see Harding, Sandra The Science Question in Feminism [Ithaca: Cornell University Press 1986]Google Scholar).

33 But elsewhere Marx writes, e.g., that class conflict ends ‘either in a revolutionary reconstitution of society at large or in the common ruin of the contending classes’ (CW, 6, 482, emphasis added). This seems more consistent with the Marx who thinks that ‘Men make their own history’ if not just as they please (CW, 11, 103). See Justin Schwartz, ‘How Not To Refute Marxism’ (unpublished MS) for a defense of the nondeterminist view.

37 In Marx’s day, and for several generations following, many European workers did become Marxist and sometimes revolutionary.

38 Real scholars working under incredibly difficult conditions in the ex-Bloc countries did much first rate work, especially on the problems of a planned economy. This is consistent with Marx’s qualified praise of the best bourgeois economics. The bourgeois counterparts of the party hacks include those whom Marx stigmatizes as ‘vulgar political economists’ such as (he thinks) Mal thus, who let their commitment to the existing order dictate their conclusions.

39 It should not be necessary to say that the interests of a group in some position have no greater moral weight merely because they are the most reliable sources for belief about a subject matter. Thus even if the standpoint of the proletariat is privileged with respect to economics, worker interests do not therefore merit greater moral consideration than those of women or Blacks.
