totle's opinions were authoritative. It seriously vitiated the marvelous
achievements of the classical economists and rendered the writings of
their epigones, especially those of Marx and the Marxian school, en-
tirely futile. The basis of modern cconomics is the cognition that it is
precisely the disparity in the value attached to the objects exchanged
that results in their being exchanged. People buy
and
sell only be-
cause they appraise the things given up less than those received. Thus
the notion of a measurement of value is vain. An act of exchange is
neither preceded nor accompanied
by
any process which could be
called a measuring of value. An individual may attach the same value
to two things; but then no exchange can result. But if there is
a
diversity in valuation, all that can be asserted with regard to it is
that one
a
is valued higher, that it is preferred to one

Values and
valuations are intensive quantities and not extensive quantities. They
are not susceptible to mental grasp by the application of cardinal
numbers.
However, the spurious idea that values are measurable and arc really
measured in the conduct of economic transactions was so deeply
rooted that even eminent economists fell victim to the fallacy im-
plied. Even Friedrich von Wieser and Irving Fisher took it for granted
that there must be something like measurement of value and that eco-
nomics must be able to indicate and to explain the method by which
such measurement is effected.Wost of the lesser economists simply
maintained that money serves "as a measure of valucs."
Now, we must realize that valuing means to prefer

b.
There is
-logically, epistemologically, psychologically, and praxeologically
--only one pattern of preferring. It does not matter whether a lover
prefers one girl to other girls,
a
man one fricnd to other people, an
amateur one painting to other paintings, or a consumer a loaf of
bread to a piece of candy. Preferring always means to love or to de-
sire
a
more than
b.
Just as there is no standard and no measurement of
sexual love, of friendship and sympathy, and of aesthetic enjoyment,
so there is no measurement of the value of commodities.
If
a man
exchanges two pounds of butter for a shirt, all that we can assert
with regard to this transaction is that he-at the instant of the trans-
action and under the conditions which this instant offers to him-pre-
fers one shirt to two pounds of butter.
It
is certain that every act of
preferring is characterized by
a
definite psychic intensity of the
feelings it implies. There are grades in the intensity of the desire to
