Definition of Rationale

Definition Last Updated 17-Dec-2015 12:51

A rationale is an argument for or against something, which may be engaging in an activity or being in a particular state; a rationale is therefore a kind of rule.

Rationales necessarily include valuations because to argue for or against something is to say that it is absolutely good or bad, or relatively better or worse than something else.

Rationales should be sound arguments, i.e. arguments that apply valid reasoning to true premises.
