Forms
The argument from authority (argumentum ad verecundiam) can take several forms. As a statistical syllogism, the argument has the following basic structure:
- Most of what authority A has to say on subject matter S is correct.
- A says P about subject matter S.
- Therefore, P is correct.
The strength of this authoritative argument depends upon two factors:
- The authority is a legitimate expert on the subject.
- There exists consensus among legitimate experts in the subject matter under discussion.
The two factors — legitimate expertise and expert consensus — can be incorporated to the structure of the statistical syllogism, in which case, the argument from authority can be structured thus:
- X holds that A is true.
- X is a legitimate expert on the subject matter.
- The consensus of subject-matter experts agrees with X.
- Therefore, there exists a presumption that A is true.

Famous quotes containing the word forms:
“The moment a person forms a theory, his imagination sees in every object only the tracts which favor that theory.”
—Thomas Jefferson (1743–1826)
“The analogy between the mind and a computer fails for many reasons. The brain is constructed by principles that assure diversity and degeneracy. Unlike a computer, it has no replicative memory. It is historical and value driven. It forms categories by internal criteria and by constraints acting at many scales, not by means of a syntactically constructed program. The world with which the brain interacts is not unequivocally made up of classical categories.”
—Gerald M. Edelman (b. 1928)
“Psychoanalysis can unravel some of the forms of madness; it remains a stranger to the sovereign enterprise of unreason. It can neither limit nor transcribe, nor most certainly explain, what is essential in this enterprise.”
—Michel Foucault (1926–1984)
