"Science of criteria" or "criteriology" is a term, originally neoscholastic, for a theory of knowledge in which judgments are warranted or justified simply by conforming to certain criteria for correct judgment. These criteria are general principles that specify what sorts of considerations ultimately confer warrant on some judgments and that tend (tacitly) to guide self-reflective persons in checking and correcting their judgments. The epistemologist's task is to formulate these principles by reflecting on the considerations present and absent in various judgments we intuitively think of as warranted and unwarranted.
Different criteria may deal with different subject matters, degrees, and sources of warrant (e.g., in perception, memory, inference). Ultimately, there must be warranting considerations other than inferability from other warranted judgments. These must be internally accessible through introspection or reflection without relying on further warranted judgments. They will not be considerations such as whether nature designed us to be reliable judges but ones such as whether we ostensibly see or recall something or intuitively grasp or clearly and distinctly conceive something.
Many epistemologists argue that critical considerations need not guarantee truth or confer certainty, and whatever warrant they confer may be defeated. For instance, if one ostensibly sees something red, one is prima facie or defeasibly warranted in judging that one actually sees something red. The judgment might not be warranted when, despite ostensibly seeing something red, one has evidence that the illumination makes everything look red. We need additional principles specifying what considerations defeat warrant.
However, if criterial considerations do not guarantee truth, what makes a set of principles genuinely warranting? Putative common contingent features such as their overall reliability rest warrant on something beyond mere conformity to these principles and may allow for alternative principles. Criteriologists (e.g., Pollock 1974, 1986) often appeal to controversial, nonscholastic, views about concepts and truth influenced by Ludwig Wittgenstein. Criteria are internalized norms (rules) about when to make and correct judgments ascribing a concept. They characterize what persons must, in order to have a particular concept, tacitly know how to do in their judging and reasoning and be tacitly guided by. Criteria individuate our concepts and thus are necessarily correct. Although warranted judgments need not be true, we have no idea of their truth completely divorced from what undefeated criterial considerations warrant. Critics often respond: Surely this norm conformity must have a purpose beyond itself, like accurately representing the world?

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).
Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.
Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:
Modern Language Association

- Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
- In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
