Of course, there is a way to reconcile the psychological approach considered here with the claim that an argument is either deductive or inductive, but never both. Similarly, deductive arguments are arguments whose premises, if true, guarantee the truth of the conclusion (Bowell and Kemp 2015). Govier (1987) calls the view that there are only two kinds of argument (that is, deductive and inductive) the positivist theory of argument. Likewise, consider the following as well: Each spider so far examined has had eight legs. It gathers different premises to provide some evidence for a more general conclusion.

If the arguer intends or believes the argument to be one that merely makes its conclusion probable, then it is an inductive argument. A valid deductive argument is one whose logical structure or form is such that if the premises are true, the conclusion must be true. So if we present an analogical argument explicitly, it should take the following form: Before continuing, see if you can rewrite the analogical arguments above in this explicit form. Consider the following argument: If today is Tuesday, then the taco truck is here. Bacteria are cells and they have cytoplasm.

Be that as it may, there are yet other logical consequences of adopting such a psychological account of the deductive-inductive argument distinction that, taken together with the foregoing considerations, may raise doubts about whether such an account could be the best way to capture the relevant distinction. According to the analogical reasoning in the teleological argument, it would be ridiculous to assume that a complex object such as a watch came about through some random process. Analogies help lawyers and judges solve legal problems not controlled by precedent and help law students deflect the nasty hypotheticals that are the darlings of professors. Along the way, it is pointed out that none of the proposed distinctions populating the relevant literature are entirely without problems. Although there is much discussion in this article about deductive and inductive arguments, and a great deal of argumentation, there was no need to set out a categorical distinction between deductive and inductive arguments in order to critically evaluate a range of claims, positions, and arguments about the purported distinction between each type of argument. It moves from a general (or universal) premise (exhibited by the phrase all men) to a specific (or particular) conclusion (exhibited by referring to Socrates). 7.
