 C - Conclusion

 

Conclusion: In logic: Last inference in an argument, that usually was to be inferred somehow.

Note that conclusions outside logic may be defined in the same way, with the difference that outside logic it may be difficult to say what were the rules of inference that were used to infer the conclusion, and also may be difficult to say whether the inferred conclusion does follow validly or plausibly given what was assumed.

Another term for conclusion in logic is consequence, and there have been developed many logical systems for inferring consequences and thinking about the properties of consequences.

It should also be argued that the conclusions lawyers argue as a rule have much less to do with logical validity than with rhetorics and existing jurisprudence (case law), and that conclusions in rhetorics need not at all to follow validly in logic, since all that is sufficient for a rhetorically valid conclusion is that it seems plausible or convincing to some public.
