Typically Marx develops his own thought through a critique of others, principally Hegel, the Left Hegelians, and the political economists (especially Adam Smith, David Ricardo, James Mill and J-B Say). Hegel features throughout Marxās early writings, most directly in the CHPR, but always in the background even when not the immediate subject of comment. By looking at Marxās critical comments about other writers something of his own approach may be discerned.
Marx and Hegel
According to Marx Hegelās most basic mistake is his inversion of subject and predicate which makes the Idea the subject and empirical reality the predicate. Marx writes in the CHPR, āThe crux of the matter is that Hegel everywhere makes the Idea into the subject, while the genuine, real subject⦠is turned into the predicate.ā3 This fundamental error of Hegelās has, according to Marx, various implications that Marx elaborates into a major critique of Hegelās methodology.
Hegelās starting point is the Idea and the abstract concepts he derives from āpure beingā. Hegelās abstractions assume the status of reality, they are hypostatised, the realisation of moments of the abstract concept becomes concrete fact. For example, on Hegelās analysis of the transition from the family and civil society to the political state Marx writes:
ā¦the transition does not result from the particular nature of the family etc, and the particular nature of the state, but from the universal relationship of freedom and necessity. We find exactly the same process at work in the āLogicā in the transition from the sphere of Essence to that of the Concept. In the āPhilosophy of Natureā, the same transition can be observed from Inorganic nature to Life. It is always the same categories which are made to supply now one sphere and now another with a soul. The problem is merely to discover the appropriate abstract determinants to fit the individual concrete ones.4
Hegelā s abstract treatment of society, i.e., starting from abstractions and treating the concrete as the embodiment of them, leads to the undifferentiated application of general concepts and terms. For example, Hegel applies the term āorganismā to the state without indicating any distinction between the state as organism and, say, an animal organism. As far as Hegelās account goes the respective structure and relation of parts of each may be the same. He defines his terms abstractly in relation to the state/political constitution not because of the specific characteristics of the state/political constitution, but because of the features of the Idea. Marx writes:
The starting-point is the abstract Idea which then develops into the political constitution of the state. We are not concerned with a political Idea but with the abstract Idea in a political form, the mere fact that I say āthis organism (i,e. the state, the political constitution) is the differentiation of the Idea into various elements, etcā does not mean that I know anything at all about the specific Idea of the political constitution; the same statement can be made with the same truth about the organism of an animal as about the organism of the state.5
Hegelās abstract and idealist starting point leads him to be more concerned to establish concrete reality as a predicate of the Idea, than to establish the specific nature of actual things.
This critique in the CHPR of the abstract idealism of Hegelian philosophy is continued in the HF. In one passage in particular Marx lampoons āspeculative philosophyā by way of an analysis of fruit using the speculative method. Hegelian analysis, according to Marx, inverts the abstract and the concrete making the abstract idea of āFruitā the true essence, substance, origin and active subject of actual fruit. He writes:
If from real apples, pears, strawberries and almonds I form the general idea āFruitā, if I go further and imagine that my abstract idea āFruitā, derived from real fruit, is an entity existing outside me, is indeed the true essence of the pear, the apple, etc., then - in the language of speculative philosophy - I am declaring that āFruitā is the āsubstanceā of the pear, the apple, the almond, etc. I am saying, therefore, that to be a pear is not essential to the pear, that to be an apple is not essential to the apple; that what is essential to these things is not their real existence, perceptible to the senses, but the essence I have abstracted from them, and then foisted on them, the essence of my idea - āFruitā. I therefore declare apples, pears, almonds, etc., to mere forms of existence, modi, of āFruitā.6
The concrete is reduced to āmere forms of existenceā or āsemblancesā of the abstract. The abstract idea āFruitā is derived from real fruit, but Hegelian speculative philosophy takes the abstract idea as the starting point and āimaginesā itself to be deriving real fruit from the idea āFruitā. As in the CHPR Marx makes the point that this approach denies significance to concrete distinctions, to the particular:
My finite understanding supported by my senses does of course distinguish an apple from a pear and a pear from an almond, but my speculative reason declares these sensuous differences inessential and irrelevant. It sees in the apple the same as in the pear, and in the pear the same as in the almond, namely āFruitā. Particular real fruits are no more than semblances whose true essence is āthe substanceā - āFruitā .7
