Argumentation

See philosophy.

Arguments are predicates and combinations of them. The act of arguing is to support or tear down claims by use of reasoning. An argument is either valid or invalid.

Invalid Arguments

There’s so many of them they’re listed under logical fallacies. See arguments that don’t even amount to being fallacies here.

Valid Arguments

The following syllogisms expand upon material implication. These are structures that don’t entail direct logical contradictions. Assuming arguments conforming to these are relevant to topic and have true premises, conclusions follow.
