Utilitarianism
An ethical theory that determines right from wrong by focusing on outcomes, aiming to produce the greatest good for the greatest number
Hedonistic Utilitarianism
A form of Utilitarianism that sees pleasure and happiness as the ultimate ends of moral decisions
The origins of Utilitarianism are often traced back to the Epicureanism of the followers of the Greek philosopher Epicurus, and it can be argued that David Hume and Edmund Burke were proto-Utilitarians
Jeremy Bentham
The English philosopher generally credited with establishing Utilitarianism as a specific school of thought, who found pain and pleasure to be the only intrinsic values and derived the rule of utility
John Stuart Mill
Bentham's foremost proponent, who named the Utilitarian movement and refined Bentham's original principles in his famous 1861 work "Utilitarianism"
Premises of Utilitarianism
Actions are considered right only if the outcome maximizes good over bad
Happiness is the only good outcome possible
If an action does not maximize happiness, it may be the incorrect choice even if morally considered
Advantages of Utilitarianism
It is a universal concept that all can understand
You don't need to practice a religion to benefit from it
It follows democratic principles
It uses an objective process to decide right and wrong
It is very easy to use
It works with our natural intuition
It bases everything on the concept of happiness
Disadvantages of Utilitarianism
Society does not solely focus on happiness when making choices
The ends never really justify the means when considering happiness
Outcomes are unpredictable when dealing with the future
Happiness is subjective
It forces you to rely on everyone else following the same moral code
It doesn't focus on the act itself to form judgments
You cannot measure happiness in tangible ways
It would allow the majority to always dictateoutcomes
Impartiality
A democratic ethical principle that official judgements and reports should be based on objective and relevant criteria, without bias or prejudice, and not take sides
Impartiality
Involves treating everyone as an equal rather than necessarily treating them in exactly the same way
Individuals may be objectively judged to require different treatment
Deontological ethics

Virtue is its own reward
Let justice be done though the heavens fall
Utilitarianism

Utilitarianism

Sentience
Whether or not something can feel pleasure and pain
If it can, it has at least one interest–to avoid pain–which may imply an ethical duty to these subjects
Rationalism
A belief or theory that opinions and actions should be based on reason and knowledge rather than on religious belief or emotional response
Common approaches to describe utilitarianism
Quantitative approach
Reductionist approach
Quantitative approach

Bentham: 'It is the greatest happiness of the greatest number that is the measure of right and wrong'
Reductionism
An approach that is used in many disciplines, including psychology, that is centered on the belief that we can best explain something by breaking it down into its individual parts
Factors that influence ethics and morality in modern society
Religious teachings and doctrines
