The philosophy of utilitarianism can trace its origins back thousands of years but it’s most famously associated with the 18th century English philosopher Jeremy Bentham. The basic principle of utilitarianism is that ones actions should be guided towards outcomes that create the greatest good for the greatest numbers of people. This simple guiding principle creates a host of challenging moral dilemmas. John Stuart Mill’s ‘Utilitarianism’ is the classic exposition of this simple and yet complex philosophy.
