We will look at deontology in more depth in Unit 3, but for now, read this basic introduction and notice the basic contrast between deontology and consequentialism. Note: Utilitarianism is a type or a subset of consequentialism. Do you think there are duties apart from consequences?
Contemporary deontologists (i.e., scholars born in the first half of the 20th century) include Józef Maria Bocheński, Thomas Nagel, T. M. Scanlon, and Roger Scruton.
Bocheński (1965) makes a distinction between deontic and epistemic authority:
Scruton (2017), in his book On Human Nature, is critical of consequentialism and similar ethical theories, such as hedonism and utilitarianism, instead proposing a deontological ethical approach. He implies that proportional duty and obligation are essential components of the ways in which we decide to act, and he defends natural law against opposing theories. He also expresses admiration for virtue ethics, and believes that the two ethical theories are not, as is frequently portrayed, mutually exclusive.
