A premise or premiss [a] is a proposition—a true or false declarative statement—used in an argument to prove the truth of another proposition called the conclusion. [1] Arguments consist of a set of premises and a conclusion. An argument is meaningful for its conclusion only when all of its premises are true. If one or more premises are ...
This rendered all facts about human action examinable under a normative framework defined by cardinal virtues and capital vices. "Fact" in this sense was not value-free, and the fact-value distinction was an alien concept. The decline of Aristotelianism in the 16th century set the framework in which those theories of knowledge could be revised. [6]
The theory that most effectively reconciles all facts in this fashion may be considered most likely to be true. Coherence is the most potentially effective test of truth because it most adequately addresses all elements. The main limitation lies not in the standard, but in the human inability to acquire all facts
The statement formed by reversing the antecedent and consequent of a conditional statement, not necessarily maintaining logical equivalence. converse domain In set theory and logic, the set of all elements that are related to any element of a given set under a specific relation.

A statement can be called valid, i.e. logical truth, in some systems of logic like in Modal logic if the statement is true in all interpretations. In Aristotelian logic statements are not valid per se. Validity refers to entire arguments. The same is true in propositional logic (statements can be true or false but not called valid or invalid).
Every argument's conclusion is a premise of other arguments. The word constituent may be used for either a premise or conclusion. In the context of this article and in most classical contexts, all candidates for consideration as argument constituents fall under the category of truth-bearer: propositions, statements, sentences, judgments, etc.
In informal logic this is called a counter argument. The form of an argument can be shown by the use of symbols. For each argument form, there is a corresponding statement form, called a corresponding conditional, and an argument form is valid if and only if its corresponding conditional is a logical truth. A statement form which is logically ...
The major premise is a general conception or moral maxim; the minor premise is a particular instance: and the conclusion is an action involved in subsuming the particular instance under the general conception or law. The conclusion is not an abstraction, as in the case of a theoretical syllogism, but consists in an action and is jussive, e.g.
