Karl Marx

Karl Marx (1818-1883) is best known not as a philosopher but as a revolutionary communist, whose works inspired the foundation of many communist regimes in the twentieth century. It is hard to think of many who have had as much influence in the creation of the modern world. Trained as a philosopher, Marx turned away from philosophy in his mid-twenties, towards economics and politics. However, in addition to his overtly philosophical early work, his later writings have many points of contact with contemporary philosophical debates, especially in the philosophy of history and the social sciences, and in moral and political philosophy. Historical materialism — Marx's theory of history — is centered around the idea that forms of society rise and fall as they further and then impede the development of human productive power. Marx sees the historical process as proceeding through a necessary series of modes of production, culminating in communism. Marx's economic analysis of capitalism is based on his version of the labour theory of value, and includes the analysis of capitalist profit as the extraction of surplus value from the exploited proletariat. The analysis of history and economics come together in Marx's prediction of the inevitable breakdown of capitalism for economic reasons, to be replaced by communism. However Marx refused to speculate in detail about the nature of communism, arguing that it would arise through historical processes, and was not the realisation of a pre-determined moral ideal.

1. Marx's Life and Works

Karl Marx was born in Trier, in the German Rhineland, in 1818. Although his family was Jewish they converted to Christianity so that his father could pursue his career as a lawyer in the face of Prussia's anti-Jewish laws. A precocious schoolchild, Marx studied law in Bonn and Berlin, and then wrote a PhD thesis in Philosophy, comparing the views of Democritus and Epicurus. On completion of his doctorate in 1841 Marx hoped for an academic job, but he had already fallen in with too radical a group of thinkers and there was no real hope. Turning to journalism Marx rapidly became involved in political and social issues, and soon found himself having to consider communist theory. Of his many early writings, four, in particular stand out. ‘Contribution to a Critique of Hegel's Philosophy of Right, Introduction’, and ‘On The Jewish Question’, were both written in 1843 and published in the Deutsch-Französische Jahrbücher. The Economic and Philosophical Manuscripts, written in Paris 1844, and the ‘Theses on Feuerbach’ of 1845 remained unpublished in Marx's lifetime.

The German Ideology, co-written with Engels, in 1845, was also unpublished but this is where we see Marx beginning to develop his theory of history. The Communist Manifesto is perhaps Marx's most widely read work, even if it is not the best guide to his thought. This was again jointly written with Engels and published with a great sense of excitement in 1848 as Marx returned to Germany from exile to take part in the revolution of 1848. With the failure of the revolution Marx moved to London where he remained for the rest of his life. He now concentrated on the study of economics, producing, in 1859, his Contribution to a Critique of Political Economy. This is largely remembered for its Preface, in which Marx sketches out what he calls ‘the guiding principles’ of his thought, on which many interpretations of historical materialism are based. Marx's main economic work is, of course, Capital Volume 1, published in 1867, although Volume 3, edited by Engels, and published posthumously in 1894, contains much of interest. Finally the late pamphlet Critique of the Gotha Programme (1875), is an important source for Marx's reflections on the nature and organisation of communist society.

The works so far mentioned amount only to a small fragment of Marx's opus, which will eventually run to around 100 large volumes when his collected works are completed. However the items selected above form the most important core from the point of view of Marx's connection with philosophy, although other works, such as the 18th Brumaire of Louis Napoleon (1852) are often regarded as equally important in assessing Marx's analysis of concrete political events. In what follows I shall concentrate on those texts and issues which have been given the greatest attention within the philosophical literature.

2. The Early Writings

The intellectual climate within which the young Marx worked was dominated by the influence of Hegel, and the reaction to Hegel by a group known as the young-Hegelians, who rejected what they regarded as the conservative implications of Hegel's work. The most significant of these thinkers was Ludwig Feuerbach, who attempted to transform Hegel's metaphysics, and, thereby, provided a critique of Hegel's doctrine of religion and the state. A large portion of the philosophical content of Marx's works written in the early 1840s is a record of his struggle to define his own position in reaction to that of Hegel and Feuerbach and those of the other Young-Hegelians.

2.1 ‘On The Jewish Question’

In this text Marx begins to make clear the distance between him and that of his radical liberal colleagues among the Young Hegelians; in particular Bruno Bauer. Bauer had recently written against Jewish emancipation, from an atheist perspective, arguing that the religion of both Jews and Christians was a barrier to emancipation. In responding to Bauer Marx makes one of the most enduring arguments from his early writings, by means of introducing a distinction between political emancipation — essentially the grant of liberal rights and liberties — and human emancipation. Marx's reply to Bauer is that political emancipation is perfectly compatible with the continued existence of religion, as the example of the United States demonstrates then. However, pushing matters deeper, in an argument reinvented by innumerable critics of liberalism, Marx argues that not only is political emancipation insufficient to bring about human emancipation, it is in some sense also a barrier. Liberal rights and ideas of justice are premised on the idea that each of us needs protection from other human beings. Therefore liberal rights are designed to protect us from such perceived threats. Freedom on such a view, is freedom from interference. What this view overlooks is the possibility — for Marx, the fact — that real freedom is to be found positively in our relations with other people. It is to be found in human community, not in isolation. So insisting on a regime of rights encourages us to view each other in ways which undermine the possibility of the real freedom we may find in human emancipation. Now we should be clear that Marx does not oppose political emancipation, for he clearly sees that liberalism is a great improvement on the systems of prejudice and discrimination which existed in the Germany of his day. Nevertheless such politically emancipated liberalism must be transcended on the route to genuine human emancipation. Unfortunately Marx never tells us what human emancipation is, although it is clear that it is closely related to the idea of non-alienated labour which we will explore below

2.2 ‘Contribution to a Critique of Hegel's Philosophy of Right, Introduction’

This work is home to the Marx's notorious remark that religion is the ‘opiate of the people’, and it is here that Marx sets out his account of religion in most detail. Just as importantly Marx here also considers the question of how revolution might be achieved in Germany, and sets out the role of the proletariat in bringing about the emancipation of society as a whole.

With regard to religion, Marx fully accepted Feuerbach's claim in opposition to traditional theology that human beings had created God in their own image; indeed a view that long pre-dated Feuerbach. Feuerbach's distinctive contribution was to argue that worshipping God diverted human beings from enjoying their own human powers. While accepting much of Feuerbach's account Marx's criticizes Feuerbach on the grounds that he has failed to understand why people fall into religious alienation and so is unable to explain how it can be transcended. Marx's explanation, of course, is that religion is a response to alienation in material life, and cannot be removed until human material life is emancipated, at which point religion will wither away. Precisely what it is about material life that creates religion is not set out with complete clarity. However it seems that at least two aspects of alienation are responsible. One is alienated labour, which will be explored shortly. A second is the need for human beings to assert their communal essence. Whether or not we explicitly recognize it, human beings exist as a community, and what makes human life possible is our mutual dependence on the vast network of social and economic relations which engulf us all, even though this is rarely acknowledged in our day-to-day life. Marx's view appears to be that we must, somehow or other, acknowledge our communal existence in our institutions. At first it is ‘deviously acknowledged’ by religion, which creates a false idea of a community in which we are all equal in the eyes of God. After the post-Reformation fragmentation of religion, where religion is no longer able to play the role even of a fake community of equals, the state fills this need by offering us the illusion of a community of citizens, all equal in the eyes of the law. But the state and religion will both be transcended when a genuine community of social and economic equals is created.

Of course we are owed an answer to how such a society could be created. It is interesting to read Marx here in the light of his third Thesis on Feuerbach where he indicates how it will not happen. The crude materialism of Robert Owen and others assumes that you can change people by changing their circumstances. However, how are those circumstances to be changed? By an enlightened philanthropist like Owen who can miraculously break through the chain of determination which ties down everyone else? Marx's response, in both the Theses and the Critique, is that the proletariat can break free only by their own self-transforming action. Indeed if they do not create the revolution for themselves — guided, of course, by the philosopher — they will not be fit to receive it.

2.3 Economic and Philosophical Manuscripts

The Economic and Philosophical Manuscripts cover a wide range of topics including much interesting material on private property and communism, and on money, as well as developing Marx's critique of Hegel. However, they are best known for their account of alienated labour. Here Marx famously depicts the worker under capitalism as suffering from four types of alienated labour. First, from the product, which as soon as it is created is taken away from its producer. Second, in productive activity (work) which is experienced as a torment. Third, from species-being, for humans produce blindly and not in accordance with their truly human powers. Finally from other human beings, where the relation of exchange replaces mutual need. That these categories overlap in some respects is not a surprise given Marx's remarkable methodological ambition in these writings. Essentially he attempts to apply a Hegelian deduction of categories to economics, trying to demonstrate that all the categories of bourgeois economics — wages, rent, exchange, profit etc- are ultimately derived from an analysis of the concept of alienation. Consequently each category of alienated labour is supposed to be deducible from the previous one. However, Marx gets no further than deducing categories of alienated labour from each other. Quite possibly in the course of writing he came to understand that a different methodology is required for approaching economic issues. Nevertheless we are left with a very rich text on the nature of alienated labour. The idea of non-alienation has to be inferred from the negative, with the assistance of one short passage at the end of the text ‘On James Mill’ in which non-alienated labour is briefly described in terms which emphasise both the immediate producer's enjoyment of production as a confirmation of his or her powers, and also the idea that production is to meet the needs of others, thus confirming for both parties our human essence as mutual dependence. Both sides of our species essence are revealed here: our individual human powers and our membership in the human community.

It is important to understand that for Marx alienation is not merely a matter of subjective feeling, or confusion. The bridge between Marx's early analysis of alienation and his later social theory is the idea that the alienated individual is ‘a plaything of alien forces’, albeit alien forces which are themselves a product of human action. In our daily lives we take decisions that have unintended consequences, which then combine to create large-scale social forces which may have an utterly unpredicted effect. In Marx's view the institutions of capitalism — themselves the consequences of human behaviour — come back to structure our future behaviour, determining the possibilities of our action. For example, for as long as a capitalist intends to stay in business he must exploit his workers to the legal limit. Whether wracked by guilt or not the capitalist must act as a ruthless exploiter. Similarly the worker must take the best job on offer; there is simply no other sane option. But by doing this we reinforce the very structures that oppress us. The urge to transcend this condition, and to take collective control of our destiny — whatever that would mean in practice — is one of the motivating and sustaining elements of Marx's attraction to communism.

2.4 ‘Theses on Feuerbach’

The Theses on Feuerbach contain one of Marx's most memorable remarks ‘the philosophers have only interpreted the world, the point is to change it’ (thesis 11). However the eleven theses as a whole provide, in the compass of a couple of pages, a remarkable digest of Marx's reaction to the philosophy of his day. Several of these have been touched on already (for example the discussions of religion in theses 4, 6 and 7, and revolution in thesis 3) so here I will concentrate only on the first, most overtly philosophy, thesis.

In the first thesis Marx states his objections to ‘all hitherto existing’ materialism and idealism. Materialism is complimented for understanding the physical reality of the world, but is criticised for ignoring the active role of the human subject in creating the world we perceive. Idealism, at least as developed by Hegel, understands the active nature of the human subject, but confines it to thought or contemplation: the world is created through the categories we impose upon it. Marx combines the insights of both traditions to propose a view in which human beings do indeed create — or at least transform — the world they find themselves in, but this transformation happens not in thought but through actual material activity; not through the imposition of sublime concepts but through the sweat of their brow, with picks and shovels. This historical version of materialism, which transcends and thus rejects all existing philosophical thought, is the foundation of Marx's later theory of history. As Marx puts it in the 1844 Manuscripts, ‘Industry is the real historical relationship of nature … to man’. This thought, derived from reflection on the history of philosophy, sets the agenda for all Marx's future work.

3. Economics

Capital Volume 1 begins with an analysis of the idea of commodity production. A commodity is defined as a useful external object, produced for exchange on a market. Thus two necessary conditions for commodity production are the existence of a market, in which exchange can take place, and a social division of labour, in which different people produce different products, without which there would be no motivation for exchange. Marx suggests that commodities have both use-value — a use in other words — and an exchange-value — initially to be understood as their price. Use value can easily be understood, so Marx says, but he insists that exchange value is a puzzling phenomenon, and relative exchange values need to be explained. Why does a quantity of one commodity exchange for a given quantity of another commodity? His explanation is in terms of the labour input required to produce the commodity, or rather, the socially necessary labour, which is labour exerted at the average level of intensity and productivity for that branch of activity within the economy. Thus the labour theory of value asserts that the value of a commodity is determined by the quantity of socially necessary labour time required to produce it. Marx provides a two stage argument for the labour theory of value. The first stage is to argue that if two objects can be compared in the sense of being put on either side of an equals sign, then there must be a ‘third thing of identical magnitude in both of them’ to which they are both reducible. As commodities can be exchanged against each other, there must, Marx argues, be a third thing that they have in common. This then motivates the second stage, which is a search for the appropriate ‘third thing’ , which is, of course, labour in Marx's view, as the only plausible common element. Both steps are, of course, highly contestable.

Capitalism is distinctive, Marx argues, in that it involves not merely the exchange of commodities, but the advancement of capital, in the form of money, with the purpose of generating profit through the purchase of commodities and their transformation into other commodities which can command a higher price, and thus yield a profit. Marx claims that no previous theorist has been able adequately to explain how capitalism as a whole can make a profit. Marx's own solution relies on the idea of exploitation of the worker. In setting up conditions of production the capitalist purchases the worker's labour power — his ability to labour — for the day. The cost of this commodity is determined in the same way as the cost of every other; i.e. in terms of the amount of socially necessary labour power required to produce it. In this case the value of a day's labour power is the value of the commodities necessary to keep the worker alive for a day. Suppose that such commodities take four hours to produce. Thus the first four hours of the working day is spent on producing equivalent to the value of the wages the worker will be paid. This is known as necessary labour. Any work the worker does above this is known as surplus labour, producing surplus value for the capitalist. Surplus value, according to Marx, is the source of all profit. In Marx's analysis labour power is the only commodity which can produce more value than it is worth, and for this reason it is known as variable capital. Other commodities simply pass their value on to the finished commodities, but do not create any extra value. They are known as constant capital. Profit, then, is the result of the labour performed by the worker beyond that necessary to create the value of his or her wages. This is the surplus value theory of profit.

It appears to follow from this analysis that as industry becomes more mechanised, using more constant capital and less variable capital, the rate of profit ought to fall. For as a proportion less capital will be advanced on labour, and only labour can create value. In Capital Volume 3 Marx does indeed make the prediction that the rate of profit will fall over time, and this is one of the factors which leads to the downfall of capitalism. (However, as pointed out by Marx's able expositor Paul Sweezy in The Theory of Capitalist Development, the analysis is problematic.) A further consequence of this analysis is a difficulty for the theory that Marx did recognise, and tried, albeit unsuccessfully, to meet also in Capital Volume 3. It follows from the analysis so far that labour intensive industries ought to have a higher rate of profit than those which use less labour. Not only is this empirically false, it is theoretically unacceptable. Accordingly Marx argued that in real economic life prices vary in a systematic way from values. Providing the mathematics to explain this is known as the transformation problem, and Marx's own attempt suffers from technical difficulties. Although there are known techniques for solving this problem now (albeit with unwelcome side consequences), we should recall that the labour theory of value was initially motivated as an intuitively plausible theory of price. But when the connection between price and value is rendered as indirect as it is in the final theory, the intuitive motivation of the theory drains away. But even if the defender of the theory is still not ready to concede defeat, a further objection appears devastating. Marx's assertion that only labour can create surplus value is unsupported by any argument or analysis, and can be argued to be merely an artifact of the nature of his presentation. Any commodity can be picked to play a similar role. Consequently with equal justification one could set out a corn theory of value, arguing that corn has the unique power of creating more value than it costs. Formally this would be identical to the labour theory of value.

Although Marx's economic analysis is based on the discredited labour theory of value, there are elements of his theory that remain of worth. The Cambridge economist Joan Robinson, in An Essay on Marxian Economics, picked out two aspects of particular note. First, Marx's refusal to accept that capitalism involves a harmony of interests between worker and capitalist, replacing this with a class based analysis of the worker's struggle for better wages and conditions of work, versus the capitalist's drive for ever greater profits. Second, Marx's denial that there is any long-run tendency to equilibrium in the market, and his descriptions of mechanisms which underlie the trade-cycle of boom and bust. Both provide a salutary corrective to aspects of orthodox economic theory.

4. Theory of History

Marx did not set out his theory of history in great detail. Accordingly it has to be constructed from a variety of texts, both those where he attempts to apply a theoretical analysis to past and future historical events, and those of a more purely theoretical nature. Of the latter, the 1859 Preface to A Critique of Political Economy has achieved canonical status. However The German Ideology, co-written with Engels in 1845, is a vital early source in which Marx first sets out the basics of the outlook of historical materialism. We shall briefly outline both texts, and then look at the reconstruction of Marx's theory of history in the hands of his philosophically most influential recent exponent, G.A. Cohen.

4.1 The German Ideology

In The German Ideology Marx and Engels contrast their new materialist method with the idealism which had characterised previous German thought. Accordingly they take pains to set out the ‘premises of the materialist method’. They start, they say, from ‘real human beings’, emphasising that human beings are essentially productive, in that they must produce their means of subsistence in order to satisfy their material needs. The satisfaction of needs engenders new needs of both a material and social kind, and forms of society arise corresponding to the state of development of human productive forces. Material life determines, or at least ‘conditions’ social life, and so the primary direction of social explanation is from material production to social forms, and thence to forms of consciousness. As the material means of production develop, ‘modes of co-operation’ or economic structures rise and fall, and eventually communism will become a real possibility once the plight of the workers and their awareness of an alternative motivates them sufficiently to become revolutionaries.

4.2 1859 Preface

In the sketch of The German Ideology, all the key elements of historical materialism are present, even if the terminology is not yet that of Marx's more mature writings. Marx's statement in 1859 Preface renders much the same view in sharper form. Cohen's reconstruction of Marx's view in the Preface begins from what Cohen calls the Development Thesis, which is pre-supposed, rather than explicitly stated in the Preface. This is the thesis that the productive forces tend to develop, in the sense of becoming more powerful, over time. This states not that they always do develop, but that there is a tendency for them to do this. The productive forces are the means of production, together with productively applicable knowledge: technology, in other words. The next thesis is the primacy thesis, which has two aspects. The first states that the nature of the economic structure is explained by the level of development of the productive forces, and the second that the nature of the superstructure — the political and legal institutions of society — is explained by the nature of the economic structure. The nature of a society's ideology is also explained in terms of its economic structure, although this receives less emphasis in Cohen's interpretation.

Revolution and epoch change is understood as the consequence of an economic structure no longer being able to continue to develop the forces of production. At this point the development of the productive forces is said to be fettered, and, according to the theory once an economic structure fetters development it will be revolutionised — ‘burst asunder’ — and eventually replaced with an economic structure better suited to preside over the continued development of the forces of production.

In outline, then, the theory has a pleasing simplicity and power. It seems plausible that human productive power develops over time, and plausible too that economic structures exist for as long as they develop the productive forces, but will be replaced when they are no longer capable of doing this. Yet severe problems emerge when we attempt to put more flesh on these bones.
