Claims, Questions, Explanations, and Arguments

Start with the function, not the sentence form

In critical thinking, sentence length or style does not tell you what the sentence is doing. A claim is presented as something that can be true or false, such as “The center closes at six.” A question requests information rather than asserting it, an instruction asks for an action, and a preference can report a personal stance without becoming an argument merely because it is strongly worded. This distinction prevents us from evaluating an utterance as an argument when it does not yet offer reasons or a conclusion.

When do claims form an argument?

An argument is a structure in which one or more reasons—the premises—are offered in support of a conclusion. That does not mean the support succeeds; an argument can be weak or mistaken. It is therefore useful to separate two questions: What conclusion is the speaker asking us to accept? What reasons are offered for it? OpenStax distinguishes checking whether statements are true from checking whether premises support a conclusion, and the Stanford Encyclopedia describes an argument as a structure in which premises provide support for a conclusion.

An explanation answers: Why did this happen?

An explanation normally has a different purpose from an argument. When a fact is provisionally accepted and we ask why or how it happened, we explain it. If someone says, “The session started late because the projector had to be restarted,” and the delay itself is not disputed, the sentence explains the delay. If the dispute is whether there was a delay at all, projector logs might instead be offered as evidence that the delay occurred. Context determines the function; the word “because” alone does not.
