Utilitarianism is a moral theory generally considered to have been founded by Jeremy Bentham, a 19th century English philosopher and social reformer. It is centered on the concept of happiness, and those who seek it. The idea is that all people seek happiness, and that it is the ultimate goal of all human beings to be happy. Therefore, according to classical utilitarianism, when a person wishes to act in an ethically sound manner he or she should strive to bring about the greatest possible amount of happiness for the greatest possible amount of people. This is known as the greatest happiness attitude. Another, similar idea is that a person should always strive, if incapable of producing happiness, to reduce unhappiness. As the theory is wholly focused on the outcome of a person’s actions, it is classed as a “consequentialist” theory, i.e. a theory that concerns it with consequences and not actions in themselves.
Utilitarianism can be seen as a highly mathematical theorem, looking at the total units of happiness that a particular action gives rise to. For instance, I might want to go out and have drinks with some friends and my boyfriend or I could find something more family oriented and do something fun with my son and my boyfriend. Consider that my son is only little for a short time, would I rather have drinks and regret the hang over later or share a memory with my little boy. Taking my son out for a night might add 10 units of happiness to the world’s total stock, whereas going out for drinks would only add a total of 6. Certainly, the latter would make a greater quantity of people happy (the former only benefiting one person), but it is the quantity of happiness produced that is of the first importance to utilitarianists. But let us look more closely at Bentham’s utilitarianism. To understand his approach more fully, it is vital that one come to an appreciation of exactly what he meant by “happiness”. His ideas here are, really, quite simple.
