Final answer:
Jeremy Bentham believed that all humans seek happiness or well-being.
Step-by-step explanation:
Jeremy Bentham, the founder of utilitarianism, believed that all humans seek happiness or well-being. According to Bentham, the principle of utility states that actions are right in proportion as they tend to promote happiness and wrong as they tend to produce the reverse of happiness. He argued that moral conduct is conduct that maximizes the good or produces the most value, which in this case is happiness or well-being.
