A number of problems surround the second question; the most obvious of which are limited time, the limited capacity of human foresight to calculate the maximum number of happiness, and the inability of the theory to advise on the time frame utilitarianism is to be applied to; how do you know the maximum number of happiness for the next 10 years doesn’t mean greater overall unhappiness in the next 50 years, so what time period should one keep in mind when considering an issue from a utilitarian stand point, 1 year, 5 years, 10, 20? This lack of clarity further adds to the impractical nature of the ideology. There are a myriad number of situations which seem very difficult to resolve without employing utilitarian principles and a very good example is the widespread use of utilitarian principles in bioethics. The best example here would obviously be the famous case of the conjoined twins Mary and Jodie. The facts in front of the court indicated that Mary was the parasitic twin who shared a heart with Jodie. In fact, Jodie’s heart was the one sustaining the functions of the parasitic twin Mary.
