Co-premise

Index Co-premise

A co-premise is a premise in reasoning and informal logic which is not the main supporting reason for a contention or a lemma, but is logically necessary to ensure the validity of an argument. [1]

Argument

In logic and philosophy, an argument is a series of statements typically used to persuade someone of something or to present reasons for accepting a conclusion.

Fallacy of the undistributed middle

The fallacy of the undistributed middle (Lat. non distributio medii) is a formal fallacy that is committed when the middle term in a categorical syllogism is not distributed in either the minor premise or the major premise.

Inference objection

In informal logic, an inference objection is an objection to an argument based not on any of its stated premises, but rather on the relationship between premise and contention.

Informal logic

Informal logic, intuitively, refers to the principles of logic and logical thought outside of a formal setting.

Lemma (logic)

In informal logic and argument mapping, a lemma is simultaneously a contention for premises below it and a premise for a contention above it.

Main contention

In both formal and informal logic, a main contention or conclusion is a thought which can be either true or false and is usually the most controversial proposition being argued for.

Premise

A premise or premiss is a statement that an argument claims will induce or justify a conclusion.

Reason

Reason is the capacity for consciously making sense of things, establishing and verifying facts, applying logic, and changing or justifying practices, institutions, and beliefs based on new or existing information.

Validity

In logic, an argument is valid if and only if it takes a form that makes it impossible for the premises to be true and the conclusion nevertheless to be false.
