Gambling has long been a moral issue. In order to address this problem by coming up with an ethical position regarding it, it is necessary to adopt a definition of gambling for this purpose. Gambling is the wagering of money or something of material value on an event with an uncertain outcome with the primary intent of winning additional money and/or material goods. Typically, the outcome of the wager is evident within a short period. Certain religions generally disapprove of gambling to some extent, even some governments through legislation, because it can have adverse social consequences.
Is it morally acceptable to gamble? I will answer by making use of the Utilitarian perspective, and since it was not qualified whether I should be pertaining to legal (state-run) or illegal gambling, I shall look into the very act of wagering itself.
I believe it is a common mistake for people to think that Mill’s moral principle will consider gambling as something good. The reasoning should of course be grounded on the tenets of Utilitarianism, such as the concepts of (1) consequentialism, which says that an act is good even if the action may not be good in itself as long as it leads to something good; and (2) Hedonism, that an act is good if it promotes pleasure and lessens pain. But this position, that gambling is good, is not in accordance to the concept of “cultivation” and is pleasure-seeking. True, we may set aside the act of risking money or anything valuable with the hope of winning more, which I deem problematic. We can look, for instance, at the pleasure experienced by the individual gambler during the game or at his/her earnings when s/he donates these to church or other positive causes (nobody knows how the funds have been procured anyway). Gambling may be justified at this level but it is perverted understanding of Utilitarianism.
An enlightened utilitarian looks at the long-term effects of his/her actions and it is in this view that gambling is seen to be bad. First, the act wagering with lack of certainty of winning is, I believe, unreasonable. It is irrational to risk anything in this manner if it is only for monetary or unimportant purposes. Sure, we can always say that earnings from gambling can be used for beneficial (even economic) reasons and we can hide the real source of the money from others. But this becomes self-defeating as seen in my second and third points: It affects the individual and can even lead to ludomania or compulsive gambling, and quoting Catholic Bishops Conference of the Philippines President Bishop Orlando Quevedo, “gambling, illegal or not, form a deadly virus that eats into the innards of a moral society, gradually wearing out its conscience and its ability to distinguish right from wrong.” A truly other-regarding position for gambling considers not only the short-term impacts but those in the long-run, as well.
