 Distinctions can be drawn between different inductive arguments. Some inductive arguments seem quite reasonable, and others are less so. There are many different ways to attempt to analyse inductive consequence. We might consider the degree to which the premises make the conclusion more likely (a probabilistic reading), or we might check whether the most normal circumstances in which the premises are true render the conclusion true as well. (This leads to some kinds of default or non-monotonic inference.) The field of inductive consequence is difficult and important, but we shall leave that topic here and focus on deductive validity.
