Deontology
Contemporary deontology

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.
