desired, indicated by higher
authority. Such an indication will often operate to narrow the limits
of the problem. This is true even if the person concerned is acting
wholly on his own initiative and responsibility (pages 29-30).

These considerations lead to the formulation of what may be called the
corollary principle for determination of the appropriate effect to be
desired in human affairs,--as follows:

In any human activity, the appropriate effect to be desired
(i.e., an end in view, a result to be accomplished) depends on
fulfillment of the requirements of

Suitability of the end in view, as determined by the factor of
the further effect desired (if such further effect is
indicated),

Feasibility of the effort to attain the end in view, on the
basis of comparative resources, as determined by the
factors of the means available and opposed, influenced by
the factor of the physical conditions prevailing in the
field of action, and

Acceptability of the results of the effort involved, as
determined by the factor of the consequences as to costs.

If, to take a further example, the known factors include the
appropriate effect desired, the means opposed, the physical conditions
prevailing in the field of action, and the consequences as to costs,
the only unknown remains the means available. The question then is,
what means need be made available for the accomplishment of the
contemplated effort? The answer to this question may be found in the
application of what may be called the principle for the determination
of the proper means to be made available in human affairs,--as
follows:

In any human activity, the proper means to be made available
depend on fulfillment of the requirements of

Suitability of the means (in kind and amount) to accomplish
the end in view, as determined by the factor of the
appropriate effect desired,

Feasibility of the effort to make such means available on the
basis of comparative resources as determined by the factor
of the means opposed, influenced by the factor of the
physical conditions prevailing in the field of action, and

Acceptability of the results of the effort involved, as
determined by the factor of the consequences as to costs.
