Who was Jeremy bentham and what philosophy for society did he promote?

Jeremy Bentham was the founder of modern utilitarianism. He believed that making moral decisions was easy; choose the action that will result in the greatest pleasure over pain. In a well known statement he said if a game of push-pin gives you more pleasure than music or poetry it is more valuable. To calculate pleasure and pain he formulated hedonic calculus to measure intensity, duration, certainty, propinquity, fecundity, purity, and extent.
