Experimental Reason and Investment

The concept of Labor cannot be derived from that of Dialectical Materialism, since the latter connotes a Necessary process, whereas the outcome of any instance of the former, like that of any human exertion, is never guaranteed in advance.  Likewise, insofar as the concept of an Invisible Hand entails a correlation with a degree of exertion, e. g. with 'hard work', it suppresses the essential uncertainty of the results of an endeavor.  Thus, if any practice exemplifies the Experimental Reason that informs all Economic activity, it is Investment.
