Of course, it is these three chapters on commodities, exchange, and  money that constitute not the core, but the entry, the vector  to the core of Marx's critique which is that capital is a historical  relation of production, of property to labor; that value is the  expropriation of the powers of labor.
 Marx advises the reader that the exploration of value will present the  greatest challenge, and then Marx proceeds to give the reader the key to meeting  that challenge.  He identifies the commodity as the commodity form  of the product of labor.  The value form of the commodity is labor  in commodity form.
 Marx assumes that the reader will be willing to struggle through the  discussion of the value forms in order to learn something new.  In this,  Marx was displaying uncharacteristic optimism.
 "The wealth of those societies in which the capitalist mode  of production prevails, presents itself as ―an immense accumulation of  commodities,..."
 The above, the opening sentence of chapter 1, might just be an  understatement.  It, the wealth of the capitalist mode of production is  more than an immense accumulation of commodities.  It is a  universe of commodities.  It is the commodity as the universe.   Both product and its means of production are at one and the same time  expressions of each other, each other's relation to labor, and the  expression of each other's relations to all commodities.  Both,  all can be exchanged for the other, for an other, for all  others.  Exchange mediates the expression, the  materialization, the realization, the accumulation, and the pocketing of  value.  Exchange then becomes the purpose of production.
 Capital begins where value commands the labor of others.  The commodity  begins where its production is of no use, satisfies no direct need of  the producer, but rather is produced for exchange.  Capital begins where  labor itself is not for the use of the laborer, satisfies no direct need of the  producer, has no value for the laborer save its value in  exchange for the means of its own sustenance or an equivalent  thereof.  Capital expands its reproduction, accumulates, as value  commanding the labor of others.
 Capitalist production, capitalist organization, ownership of the means of  production is measured by its products, is the measure of the  products.  Production is, of, by, for  value.
 Social living labor, and the labor objectified, materialized in the  private ownership, in the property of the means of production are each  reproduced in the existence of the other.  The value form of the means of  production is the existence of labor as a commodity.  This mutual  reproduction is based on the historical separation, the opposition of the means  of production which are simply the conditions of labor to labor itself.   Without that separation, that opposition, there is no organization of labor in  commodity form.  Value is itself the composed identity of this  opposition, where the opposites are mediated.
 The commodity in its specific form, as a shirt, a gallon of milk, a  locomotive,  is useless to the producer.  It exists as a sink,  a mule, a vehicle for carrying value to market.  The capitalist  purchaes the use-value of labor, its ability to  produce commodities, paying a wage which is calculated and distributed by  the time of production.  With this purchase, the capitalist obtains  the power of labor to reproduce its social organization, its  wage, its equivalent of subsistence [and even improvement] in less  time than working time required by the capitalist.  It is this power  of labor to sustain more than its own existence, "more" than  just its individual existence and "more" than just the immediate  needs of both its individual and collective existence, in less  than the total time of its existence, that is purchased by the  capitalist.  It is this power of labor when purchased  that becomes  the property of the capitalist, that becomes the basis of accumulation, that is  converted into greater masses of the commodities that now command it to  labor for the creation of greater masses of commodities that command  it.  It is this power that is inverted into value.
 II.  Marx continues his exploration of the  commodity with an analysis of "The two poles of the expression of  value: Relative form and Equivalent form."  Here Marx states, "The whole mystery of the form of value lies hidden in this elementary  form. Its analysis, therefore, is our real difficulty."
 Using the well-worn example of the line and the coat, Marx  begins his critique through the representation of the relation of  equivalence, 20 yards of linen = 1 coat.  The linen, for Marx, expresses  its value in the coat.  The linen has value relative to the coat.  The  coat represents value in the equivalent form.
 Marx continues:
 The relative form and the equivalent form are  two intimately connected, mutually dependent and inseparable elements of the  expression of value; but, at the same time, are mutually exclusive, antagonistic  extremes – i.e.,  poles of the same expression. They are allotted respectively to the two  different commodities brought into relation by that expression. It is not  possible to express the value of linen in linen. 20 yards of linen = 20 yards of  linen is no expression of value. On the contrary, such an equation merely says  that 20 yards of linen are nothing else than 20 yards of linen, a definite  quantity of the use value linen. The value of the linen can therefore be  expressed only relatively – i.e.,  in some other commodity. The relative form of the value of the linen  presupposes, therefore, the presence of some other commodity – here the coat –  under the form of an equivalent. On the other hand, the commodity that figures  as the equivalent cannot at the same time assume the relative form. That second  commodity is not the one whose value is expressed. Its function is merely to  serve as the material in which the value of the first commodity is expressed.  
 Here is where we get some head scratching--  expressions of the value form that are inseparable, mutually dependent, and  mutually exclusive? How can any things be mutually dependent, inseparable, and  at the same time mutually exclusive?  No things can  exist simultaneously that are inseparable and  mutually exclusive.  But Marx is not discussion the physical  quantities of being.  He is exploring the expressions, the  manifestations, the commerce of and in social relations.  In  that commerce value has forms, moments of expression  in commodities that, while dependent upon the existence of the commodity itself  as a value, excludes the expression of that other moment in that  particular commodity.   
 Is it really, can it really be, that simple?   Yes, and as Marx explicitly remarks, the very simplicity is the source of such  difficulty. 
 If we look back at a previous iteration of these  value expressions in Marx's notebooks, we find what is in my opinion, a much  cleaner expression, and resolution, of this apparent  antagonism:
 Let  us consider exchange between linen-producer A and coat-producer B. Before they  come to terms, 
 A  says: 20 yards of linen are worth 2 coats (20 yards  of linen = 2 coats), 
 But  B responds: 1 coat is worth 22  yards of linen (1 coat = 22 yards of linen).  
 Finally,  after they have haggled for a long time they agree: 
 A  says: 20 yards of linen are worth 1  coat,
and B says:  1 coat is worth 20 yards of linen.  
 Here  both, linen and coat, are  at the same time in relative value-form and in  equivalent form. But, nota bene, for two different  persons and in two different expressions of  value, which simply occur (ins Leben treten) at  the same time. For A his linen  is in relative value-form – because for him the initiative proceeds  from his commodity – and the commodity of the  other person, the coat, is in equivalent form.  Conversely from the standpoint of B.  Thus one and the same commodity never possess,  even in this case, the two forms at the same time in the  same expression of value. 
 (c)  Relative value and equivalent are only forms of values.  
 Relative  value and equivalent are both only forms of  commodity-value. Now whether a commodity is in one form or in the polar opposite  depends exclusively on its position in the expression of  value. This comes out strikingly in the simple  value-form which we are here considering to begin with.  As regards the content, the  two expressions: 
 1.  20 yards of linen = 1 coat or 20 yards of linen are worth 1  coat,
2. 1 coat = 20 yards of linen or 1 coat is  worth 20 yards of linen 
 are  not at all different.  As regards the form, they are not only  different but opposed. In  expression 1 the value of the linen is expressed relatively.  Hence it is in the relative value-form whilst  at the same time the value of the coat is expressed as  equivalent. Hence it is in the equivalent  form. Now if I turn the expression 1 round I obtain expression 2. The  commodities change positions and right away the  coat is in the relative value-form, the linen  in equivalent form. Because they have  changed their respective positions in the same expression of  value, they have changed value-form  (die Wertform gewechselt).
   The forms are the moments of expression of the different facets composing the value relation.  Marx makes it clear that regarding the content of the value relation itself, the expressions are not at all different.  Regarding the forms, they exist only opposite to each other.  A single commodity can never exist in the two forms at the same time.  The forms are moments.
So....  so if it's that simple, can it really be that important?  Again, the answer  is "yes."  In exploring the forms of expression of value, Marx is  essentially rotating the commodity through the value  relationship.  Through this rotation, Marx establishes that the value in  exchange of the commodity is not produced in the markets.  Value  is not a result of the relation of the commodity to all other commodities.   Value is not the product of all commodities in relation to each other.   Value is not the product of any or all commodities relative to the single  commodity that exists as equivalent to all commodities but is itself no  commodity, money. 
 The forms of the expression of value are important in the  process of exchange in that these forms are moments in the calculus of the  realization of the value aggrandized in production.
 Further, because all commodities can be expressed in both  relative and equivalent forms,  all labors are equivalent, all  labors are relative.  All labors, no matter the advanced or rudimentary  level of technique, can be expressed in any other labor.  All labors can be  expressed in relative and equivalent forms.  All labors are  equivalent,  because they can be expressed, compared,  quantified by and in a single measure, a single dimension, a single  proportion.   Labor is the source of value because labor itself   has been transformed, clarified, reduced to a common social substrate,  time.  Time really is of the essence.
 Marx puts it this way in The Poverty of Philosophy: 'Time  is everything, man is nothing; he is at most time's carcass.' And he puts it  this way in the Grundrisse: 'Economy of time - to this all economy  ultimately reduces itself.' He wasn't kidding.
 III.  Because value has  the relative and equivalent forms of expression, because all commodities are  values, and because no commodity can simultaneously express its  relative and equivalent forms, some representation of value which  mediates these forms is required for exchange to proceed.  The mediations  of value require the services of an inter-mediation.  The inter-mediation  must embody the disembodied value from the  commodity. 
What is embedded in the commodity, value, exists in  latency, as potential.  The commodity's actual existence as both  useful article and a value, given the social relations of production that  give it life, the social relations that give the commodity the power over  the human being, the social relations that give the commodity its  existence as private property, is threatened  by  these exact relations, by its existence as private and not social  production.  
The commodity may not be useful, and the  value goes unrealized.  The commodity may be useful,  but the market may discount its value based on the average  time required for the reproduction of all such commodities.   The value aggrandized in production is comes to the market on a wing and a  prayer, as wing and a prayer, and money is the answer to all the  prayers.  It is the ascension of the commodity, its  transubstantiation.   
 Without the inter-mediation, commerce cannot proceed.   Accumulation cannot occur.  Reproduction  ceases.  The individual  commodities remain individual commodities, oscillating in value forms, but not  realizing the value relationship.  Barter can continue.  Trade can  grow.  Capital, however, as the expanding universe of commodity  production, as the accumulation of value as value is impossible. 
 And this is where Marx is taking us in this first chapter of  volume, to the role of money as the mediator of the value forms; to money as the  disembodied embodiment of all the substance of all commodities; toward the  conflict between accumulation of value and the growth of the means of  production.
