An Introduction to the Ethics of Belief in the Criminal Justice System

In this article, by adopting a descriptive-analytical method, using library tools, carrying out an interdisciplinary study and taking the general meaning of ethics into consideration, the terms "thought and belief", their relationship with the ethics of criminal justice and their application in some pillars, are first explained. Then, with an emphasis on a new reading of William Kingdon Clifford's theory of morality, as well as some moral concepts such as, rational responsibility and self-deception, the intellectual, epistemological foundations and beliefs of some elements of the criminal justice system is critiqued. Furthermore, the development and advancement of his moral logic in the application of this important matter in related issues is addressed.The explanation provided is, we believe that in decision-making bodies, and especially in important professions which deal with legislation and litigation, the holders of these rights are morally responsible to be prudent and criticize a belief based on a justifiable reason, and consequently observe the decision, seek the truth and make the right decision based on the facts. This is because they are morally responsible to think more carefully, find more realistic evidence, and to make more informed decisions and judgments in order to achieve a correct and right belief. Furthermore, they must ensure that there is a logical and rational relationship between their belief and reason. Fuzzy Logic was the criterion and logic employed in order to evaluate the ethics of belief.
