Rationality and Gambling

As has been previously discussed, merely by virtue of being a means to an end of acquiring a good or service, spending is Rational behavior.  Accordingly, spending money while getting nothing in return seems to qualify as irrational behavior--gambling, for example.  But, to the contrary, the latter well exemplifies Rationality.  For, the concept of Reason involved is Humean, i. e. the Means-End relation is an application of the Cause-Effect relation, and, hence, is a Constant Conjunction, entailing no Certainty.  Thus, Instrumental Reason is fundamentally Experimental Reason, i. e. whether or not an End ensues from a Means is never Necessary, regardless of past regularity.  Likewise, spending can always fail, e. g. the recipient of money grabs it without handing over the bought item, or the good disappoints in one respect or another.  On that basis, therefore, gambling is the quintessence of the Rationality of spending, instances of which include not only playing slot-machines and the lottery, but any investment, as well.
