The Ultimate Foundation of Economic Science [ de Mises]



[Nona Seção do Capítulo Quarto]


The Examination of Praxeological Theorems



The epistemologist who starts his lucubrations from the

analysis of the methods of the natural sciences and whom blinkers

prevent from perceiving anything beyond this field tells us

merely that the natural sciences are the natural sciences and

that what is not natural science is not natural science. About the

sciences of human action he does not know anything, and therefore

all that he utters about them is of no consequence.

It is not a discovery made by these authors that the theories of

praxeology cannot be refuted by experiments nor confirmed by
their successful employment in the construction of various gadgets.

These facts are precisely one aspect of our problem.

The positivist doctrine implies that nature and reality, in

providing the sense data that the protocol sentences register,

write their own story upon the white sheet of the human mind.

The kind of experience to which they refer in speaking of

verifiability and refutability is, as they think, something that

does not depend in any way on the logical structure of the human

mind. It provides a faithful image of reality. On the other hand,

they suppose, reason is arbitrary and therefore liable to error

and misinterpretation.


 



This doctrine not only fails to make allowance for the fallibility

of our apprehension of sense objects; it does not realize that

perception is more than just sensuous apprehension, that it is an

intellectual act performed by the mind. In this regard both

associationism and Gestalt psychology agree. There is no reason

to ascribe to the operation the mind performs in the act of becoming

aware of an external object a higher epistemological dignity

than to the operation the mind performs in describing its own

ways of procedure.


 



In fact, nothing is more certain for the human mind than

what the category of human action brings into relief. There is

no human being to whom the intent is foreign to substitute by

appropriate conduct one state of affairs for another state of affairs

that would prevail if he did not interfere. Only where there is

action are there men.


 



What we know about our own actions and about those of other

people is conditioned by our familiarity with the category of

action that we owe to a process of self-examination and introspection

as well as of understanding of other peoples' conduct.

To question this insight is no less impossible than to question

the fact that we are alive.



 

He who wants to attack a praxeological theorem has to trace it

back, step by step, until he reaches a point in which, in the chain

of reasoning that resulted in the theorem concerned, a logical

error can be unmasked. But if this regressive process of deduction

ends at the category of action without having discovered a vicious
 

link in the chain of reasoning, the theorem is fully confirmed.

Those positivists who reject such a theorem without having

subjected it to this examination are no less foolish than those

seventeenth-century astronomers were who refused to look

through the telescope that would have shown them that Galileo

was right and they were wrong.
