Section 3
All commodities have a value-form common to them all. That is all
commodities' values can be represented in the same way; their Money
Form. In other words, any commodity can be represented as so many
Pounds, Euros, Dollars or whatever the monetary unit happens to be.

But, expressed in this equation are two different things. The first
thing, the linen is having its Value expressed, whereas the coat is
acting as the unit of measure of that value. The linen is acting
here as 'relative value' whereas the coat acts as the 'equivalent'form of value.
The Exchange Value of any commodity always takes this Value Form of
being expressed as a certain quantity of some other Use Value. The
Relative Form (the linen) and the Equivalent Form (the coat) are
mutually dependent and yet exclusive. It is meaningless to say that
1 coat = 1 coat, or to say £1 = £1. It only makes sense if you say
something like 1 lb. Of apples = (is worth) £1.

You cannot measure linen against coats by any measure such as length,
weight, hardness or even utility (because utility varies for each
person, and even for the same person over time). You can only
measure linen against coats as being embodiments of Value itself.
Value, as an abstract concept like length, weight, or hardness are
abstract concepts. The fact that a room is four times longer than a
table does not in any sense imply that four tables equals one room,
other than the sense that they embody the same degree of extension in
space-time. 20 yards of linen = 1 coat only in the sense that both
embody an equivalent amount of Value. The only quality they have
which makes this comparison possible is that of Value.
So, both have the quality of Value, and it is that which allows them
to be compared. But, if I state 20 yards of linen = 1 coat, then the
unit of Value is coats, and it is in these units that the Exchange
Value of the linen is expressed. Just like if I think that people's
feet is a useful unit of measurement, I might say 1 table = 6 feet.
I would not say 6 feet = 1 table, or 1 foot = 1/6 table.
Length is an abstraction. It is abstracted from the fact that all
objects have extension i.e. they occupy a certain quantity of
space-time. But, this abstraction can take physical form in the
shape of a foot rule, or a standard metre etc. In the same way,
Exchange Value can take physical shape in the form of some standard
unit of measurement. Here it is the coat.


Just as the intensity of light is a function of the source of the
photons, so the quantity of Value is a function of the source of the
abstract labour that is its substance. So, the product of 1 hour's
labour by a brain surgeon, is the source of more abstract labour, and
therefore Value, than an hour's labour by an unskilled machine
minder, just as 1 hour's sunlight, produces more photons, and
therefore intensity of light than 1 hour's candlelight.

People seem to Value the skilled labour of singers like Robbie Williams much higher than that of say a nurse, because they are prepared to pay much more for the product of the former. |
“It
is the expression of equivalence between different sorts of
commodities that alone brings into relief the specific character of
value-creating labour, and this it does by actually reducing the
different varieties of labour embodied in the different kinds of
commodities to their common quality of human labour in the abstract.”
(p 57)
So, if we excluded the Value of the cotton from the linen, and the
linen from the coat, so that all we were comparing was the living
labour expended in both (the value added) then, if it takes 1 hour to
weave the 20 yards of linen, and 1 hour to make the coat, if 40 yards
of linen exchanges for 1 coat, we know that 2 hour's of weaver's
labour is equal to only 1 hour of tailor's labour.
In reality, although we think that what we are exchanging is
commodities, what we are really exchanging is amounts of labour-time,
just as was the case in the examples provided earlier from
anthropological studies. For example, the peasant who works on the
blacksmith's fields while the blacksmith shoes his horse. But, not
all concrete labour is the same. Marx makes this clear in quoting
Ben Franklin .

The illusion
that we are exchanging commodities, when, in fact, we are really
exchanging amounts of our labour-time, Marx calls 'commodityfetishism'.
Human Labour
is not itself Value even though it creates Value. Rather like a
candle is not light, but is the source of photons that are the
substance of light. Labour only becomes Value through its product
i.e. when it is formed in some product Use Value. How much that
Value is is measured in labour-time, but its relative size, its
Exchange Value, can only be expressed in terms of some other Use
Value. In the same way that the light from the Sun can be expressed
as so many candle power, or the power of an engine can be expressed
as so many horse power, so the Exchange Value of 100 yards of linen
can be expressed as so many coats. That is so even though the units
of measurement may no longer bear any resemblance to their original
form.

The same is
true the other way around, if the time required for producing linen
stays the same, but the time required for producing coats is halved,
then 20 yards of linen will now equal 2 coats. If the labour-time
required to produce both linen and coats doubled then 20 yards of
linen would continue to equal 1 coat, because both would still
contain the same amount of labour-time. The Value of each measured
in labour-time would have doubled, but their Exchange Value would
remain the same. There would only be a change in their Exchange
Value, if both were compared with some third commodity.
If the
labour-time required for ALL commodities rises by the same proportion
then their Exchange Values remain constant, although the Value of all
of them will have risen. Its important to note that this is NOT the
same as inflation, therefore, where all prices rise. If the
labour-time required for production of all commodities rises in the
same proportion, the result is not higher prices, but a reduction in
the quantity of commodities that can be produced in a given time. In
other words a reduction in real wealth.
The Value
Form consists of this, the Relative Form of Value (20 yards of linen)
is expressed in a certain quantity not of Exchange Value, but in a
definite quantity of Use Value i.e. the Equivalent Form of Value (1
coat). A quantity of Exchange Value cannot be expressed as an
equivalent amount of Exchange Value. It is meaningless to say £1 =
£1, just as its meaningless to compare a certain amount of Use Value
to the same Use Value e.g. 1 apple = 1 apple.

“Such
expressions of relations in general, called by Hegel reflex
categories, form a very curious class. For instance, one man is king
only because other men stand in the relation of subjects to him.
They, on the contrary, imagine that they are subjects because he is
king.” (note 1 p 63)
This relation, which as Marx says escapes bourgeois economists,
unlocks the riddle of money, which we will come to later.
Importantly, the Use Value that serves as the equivalent form of value
is also the materialisation of Abstract Labour-time, and at the same
time the product of a specific type of concrete labour.
“This
concrete labour becomes, therefore, the medium for expressing
abstract human labour. If on the one hand the coat ranks as nothing
but the embodiment of abstract human labour, so, on the other hand,
the tailoring which is actually embodied in it, counts as nothing but
the form under which that abstract labour is realised. In the
expression of value of the linen, the utility of the tailoring
consists, not in making clothes, but in making an object, which we at
once recognise to be Value, and therefore to be a congelation of
labour, but of labour indistinguishable from that realised in the
value of the linen. In order to act as such a mirror of value, the
labour of tailoring must reflect nothing besides its own abstract
quality of being human labour generally.

Hence, the second peculiarity
of the equivalent form is, that concrete labour becomes the form
under which its opposite, abstract human labour, manifests itself.”
(p 64)
A commodity is both a Use Value and a Value. That
is it has utility (for someone) and it is the product of human
labour. Its Value is the amount of labour-time required for its
production. Technically, however, as Marx points out, it only has
Exchange Value, when this Value takes an independent form. That is
when the commodity is brought into contact with, and expressed in
relation to some other commodity. That is when this Value ceases
being Individual and becomes social.
In every society throughout history the products
of human labour are Use Values. But, it is only when the labour
spent in producing such Use Values becomes expressed as a quality of
that article, as its Value, that it becomes a commodity.

At the Chicago Mercantile Exchange, the relative prices of thousands of commodities are determined minute by minute. |
So, 20 yards of linen might = 1 coat, but 2 oz.
Gold, or 10 cwt. of potatoes and so on. What at first seems an
accidental relation of exchange of all these commodities is now,
however, uncovered. The Value of any commodity does not change
because it is exchanged against another, all that changes is the
units in which it is expressed – coats, gold, potatoes. The Values
of commodities remain constant (provided there is no change in the
labour-time required for their production), and it is these Values
which determine the proportions in which they exchange – their
Exchange Values – not vice versa.
