Utilitarianism requires us to do what produces the greatest pleasure instead of pain. In reality, it is an impossible task to add up all the pleasures and pains that would result from various alternatives. And he seems to ignore humanism. For example, you see a person crossing the street without realizing that a car is coming towards him and within seconds an accident will occur. Based on utilitarianism, you should first consider all possible actions you can take. And then, to determine which action would result in the most happiness, you would have to calculate all the pleasures you will get from each alternative, e.g. Do nothing, get this person's attention, etc. While doing the calculations, the accident happens. Obviously, acting as a utilitarian in this scenario leads to the worst outcome. And as humans, we sometimes take an action for humanitarian reasons or personal beliefs. Let's take karma as an example: karma is the belief that one's current or previous actions would determine or influence one's future existence. When you do good things for others, others are more likely to do good things for you. And we all want to pursue a happy and pleasant future. I also won't plug myself into the experience machine since there are other things important to people besides pleasure. The pleasure we get from being in the car is not what we are looking for.
