Everything we do is a decision, from spending your time watching Netflix® instead of writing a philosophy paper or waking up instead of pushing the snooze button on an alarm clock. With making these decisions, we tend to have patterns, called behaviors. When deciding what behaviors or actions are right or wrong, we can look to different principles or branches of beliefs. People who tend to look for which decision grants the most pleasure, most likely believe in the Hedonism school of thought.
Andrew Moore (2004) states psychological hedonism claims, our only motivation is pain and pleasure, while ethical hedonism claims only pleasure has worth and only pain has disvalue. For this paper, I will discuss hedonism as a general topic. In a basic sense, people who believe in hedonism, take actions to either maximize pleasure or minimize pain. Pleasure can contain various feelings that contain happiness, delight, enjoyment, joy, and the like. Pain can contain various feelings that contain strain, agony, irritation, misery, and the like. Decisions we make can be: some pleasure now or more pleasure later, some pain now for a lot of pleasure later or a small amount of pleasure throughout time, pain for others pleasure, or pleasure for others pain; there are many ways to twist situations. Finding which decision that generates the most pleasure or minimizes the most pain can become confusing. To better organize decisions, there are units of measurements for pleasure, a hedon, and pain, a dolor (people.umass.edu). Jeremy Bentham (1789) defined the aspects of hedons and dolors: intensity, duration, certainty, propinquity, fecundity, purity, and extension to others. The final aspect, extension to others, is important, because otherwise hedonism would justify such things as rape and murder.
Hedonism's effectiveness can be put to the test through thought experiments. A popular thought experiment is the happy sadist.
