According to Immanuel Kant (1724-1804), a German philosopher, deontology is an ethical approach centered on rules and professional duties. Deontology derives from the Greek deont, which refers to that which is binding. Kant’s deontological philosophy stemmed from his belief that humans possess the ability to reason and understand universal moral laws that they can apply in all situations. Unlike many other ethical theories, deontology does not focus on the consequences of individual actions. Personal emotions behind actions also do not matter within Kantian deontology because Kant believed humans do not always have rational control over their feelings. Instead, the intent behind chosen actions holds far more importance. Therefore, deontology proponents judge actions based on what most people consider to be morally correct, regardless of actual consequences.
