different between deontological vs consequentialism

English

From deontology +? -ical (1832). The specialised sense in normative ethics is due to C. D. Broad (1930).

deontological (comparative more deontological, superlative most deontological)

(ethics, philosophy) Of or relating to deontology.
- 1930, C. D. Broad, Five Types of Ethical Theory, 206f.
  Deontological theories hold that there are ethical propositions of the form: 'Such and such a kind of action would always be right (or wrong) in such and such circumstances, no matter what its consequences might be.'
Antonym: non-deontological

consequential +? -ism, coined by British analytic philosopher G. E. M. Ascombe in 1958.

consequentialism (countable and uncountable, plural consequentialisms)

(ethics) The ethical study of morals, duties and rights with an approach that focuses consequences of a particular action or cause.
(ethics) The belief that consequences form the basis for any valid moral judgment about an action. Thus, from a consequentialist standpoint, a morally right action is one that produces a good outcome, or consequence.
