I presume you are limiting this definition to elementary binary deductive logic, AKA Aristotelean logic, AKA Boolean logic?

Could you not also be forced to grant that binary inductive (or binary probabilistic) logic, multi-valued (rather than binary) logic, analog logic (logic of continuous values), neural (networked) logic, and quantum logic are also logics, but for its own specialized (simplified) reasons your textbook failed to mention them?

It's not really limiting the definition. Even in the areas you mention, "logical" means the same thing: in accordance with the rules of inference (whatever those rules might be). The only reason I brought up arguments is because I assumed that Plotin was talking about deductive logic as this is what the title of the thread suggests. That said I am finding it difficult to understand much of what's being posted in this forum so maybe I got it wrong. Perhaps Plotin should reiterate.

I don't have a textbook, by the way. I have about 40. That's probably why I don't have a girlfriend.

You are correct. I am still philosophy ignorant.I beg your patients. I have taken what I understand (be it philosophy mathematics whatever) and morphed it to what I can understand.Not necessarly what you understand.pljames

When you say "in accordance with the rules of inference (whatever those rules might be)" do you mean that the derived conclusion or the correct application of rules of inference means that the conclusion or successful application is "logical"? For example, Plato's works were mostly thought out prior to Aristotle's codification of the rules of binary logic, yet you would surely testify that Plato's works were logical? Would you also say that a solved puzzle is logically correct?

I think what I am getting at here is that as Leo suggested, we are dealing with various levels of abstraction. There is the study of logic(s). There are logics. There are applications of logic. What is "logical" is any correct application of some logic.

And I stand corrected too: logic applies to the development of human Polemic or poetry or basic writing by the use of the words we have created no doubt in time. But the reality of written communication evolves into the formal presentation of anything like axioms as well.

And to ask, you, Yada yada, are axioms really a second order to ordinary sentential logic in your view, some form of modal logic of formal experiencing in being logical.
