Deductive arguments attempt to provide logically conclusive support for their conclusions.
Validity means that the argument's structure is sound, and if the premises are true, the conclusion must also be true.
If a deductive argument is not valid, it means that the conclusion does not necessarily follow from the premises, even if the premises are true.
Soundness in a deductive argument requires both validity and true premises. Soundness guarantees the truth of the conclusion.
All deductive arguments aim to establish a conclusion with certainty, which is achieved through the logical relationship between premises and conclusion.
Premise indicators signal the introduction of premises in an argument. Common examples include "because," "since," "for," "as," "given that," and "due to."
Phrases that are not premise indicators include "therefore," "so," "thus," "consequently," "hence," and "it follows that." These phrases signal conclusions.
