' An Introduction to the Principles of Morals and Legislation' Summary

Bentham's principle of utility regards "good" as that which produces the greatest amount of pleasure, and the minimum amount of pain; and "evil" as that which produces the most pain without the pleasure. This concept of pleasure and pain is defined by Bentham as physical as well as spiritual. Bentham writes about this principle as it manifests itself within the legislation of a society. He lays down a set of criteria for measuring the extent of pain or pleasure that a certain decision will create.

Bentham argues that certain unnecessary laws and punishments could ultimately lead to new and more dangerous vices than those being punished to begin with. He is of opinion that the concept of the individual pursuing his or her own happiness cannot be necessarily declared "right", because often these individual pursuits can lead to greater pain and less pleasure for the society as a whole. Therefore, the legislation of a society is vital to maintaining a society with optimum pleasure and the minimum degree of pain for the greatest amount of people.
