When is an argument considered valid?

An argument is considered valid when the conclusion logically follows from the premises. This means that if the premises provided are true, the conclusion must also be true, given the structure of the argument. Validity focuses on the relationship between the premises and the conclusion rather than the actual truth of the premises themselves. For instance, in a valid argument, it's impossible for the premises to be true while the conclusion is false. This logical structure is crucial in assessing the soundness of an argument, as it defines whether the reasoning process is coherent and reliable.

The other options pertain to aspects that do not determine the validity of an argument. Popular opinion and emotional language can influence people's acceptance of arguments, but they do not establish logical coherence. Likewise, a well-structured format may make an argument easier to follow, but the underlying logical connections are what ultimately define whether an argument is valid.
