One of the objections against Utilitarianism is what is called the Problem of Measurement, which takes the form of the following question: Is it possible to quantify happiness? How exactly should we quantify pleasure and pain? Jeremy Bentham, the father of Utilitarianism, came out with an attempt to do so objectively. He called it the "Felicific Calculus" Also, it is sometimes called "The Hedonic Calculus." Match the question with the right answer. What is intensity? Incorrect match: How vivid the pleasue or pain is What is duration? Correct match: How long a pleasure or pain is expected to last What is certainty? Incorrect match: How likely it is other will experience the pleasure or the pain What is proximity? Incorrect match: How likely it is to result What is fecundity? Correct match: To what extent it will lead to other pleasures What is purity? Correct match: How free from pain it is What is extent? Correct match: How many people it affects
