SEMAINE D'ÉTUDE SUR LE ROLE DE L'ANALYSE ECONOMETRIQUE ETC.

be dominated by a general principle (represented by the learn- 
ing process of human beings) (%). 
There is one important respect, however, on which the 
following analysis will not take a path symmetrical to the one 
followed by marginal analysis. The model will be kept at a 
sufficiently high level of generality, so as to remain neutral 
with respect to the institutional organization of society. The 
preoccupation is that of singling out the necessary conditions 
for efficiency and equilibrium growth — conditions which will 
emerge as independent of any particular institutional set-up 
that society might choose to adopt. 
{°) It may be useful to add a warning to the reader at this point. To 
ake human activity, i.e. labour, as the only non-produced factor of pro- 
luction must not be interpreted as meaning that «labour is the only 
scarce factor », as — I have noticed — some of my friends, while discussing 
the present work with me, have tended to do. Such an interpretation 
would be incorrect: scarcity presupposes some aim the attainment of 
which is limited by the existing quantity of the factor. But no such aim, 
imited by the existing quantity of labour, is present here. As the reader 
will see presently, the systems of equations which will be considered vield 
solutions for relative prices and relative quantities. To say, in such a 
context, that labour is scarce has no sense.
