In a strange way I sense you're agreeing with what I'm getting at -- that all systems can't justify themselves -- but adding disagreements on the side that needn't be there.
Of course we agree on that.
However, whether it´s you or me who adds some unnecessary disagreement is a matter of perspective.
I just don´t know why
a. you make such a fuzz about an actually trivial fact, and
b. why you are singling out "reason" of all systems.
But let me come back to half of your post only after getting to the essential stuff that I think we're disagreeing on:
Yes, logical systems can't justify themselves. My appeal go the 1-2-3 logical stuff is making that point *logically*, instead of just saying "all systems are self-contradictory" -- a statement that needs to be backed up. It's as if (to me) you're agreeing with my conclusion but attempting to shoot down the logic behind it.
No, I am not shooting down the logic behind it. If I would accept your premise there wouldn´t even be any need to shoot down the logic behind it - because you would have already established that logic is not the appropriate criterium to approach the issue.
What I am saying is: If by all means you want to do away with the validity of axioms that you and I are demonstrably unable to do without (you can´t question reason without employing reason, and I can´t justify reason by means of using reason) you are creating an impassé.
Reason is (just like any system) a system that can´t justify itself. So what? Demonstrable fact is that we can´t do without it, and that you don´t have
a. anything to offer that wouldn´t suffer from the same "problem", and
b. would prove as demonstrably axiomatic as reason.
I don't understand what you mean when you say "purely academic, abstract limitation." These "academic" thoughts have direct consequences upon our interactions with the real world: e.g., if a person "knows" through this weird reductio ad absurdum logic that (as you agree with, sans my reasoning behind it) systems are self-contradictory
Allow me to interrupt you here for correctness´sake:
Being unable to justify itself by itself is not the same as being "self-contradictory" (the opposite - i.e. what you are doing - is self-contradictory: using the means of the system to deconstruct it). But that just as a side-note.
, then this could easily add humility and wonder to those think that reason is a panacea and end-all goal for basically everything.
Reason being an end goal? Who would be so stupid to believe that? Reason is a
tool. That a screw driver is not the appropriate tool to create or fix a screw driver may be regrettable, it may be (by virtue of your demand) lead to an infinite regress or whatever), but it´s not a logical problem.
And let me remind you that the OP question was not "Why consider reason the end-goal for basically everything?" (which, btw., is nonsense, because an end goal is, by definition not "for" anything, but everything is for the end goal) but "why
listen to reason?". You have raised the bar quite a bit since, haven´t you?
At the same time, consider the very *wording* of the OP: it's meant as a type of thought experiment, but with a deeper point, and I don't think dividing the world into "academic" and "non-academic" is answering anything.
What I mean by "purely academic" is: I can´t use it for anything, and the problem it creates have no reflection in my life. Since reason is (as both your and my approach confirm here time and again) axiomatic, undisposable, and inevitable when it comes to creating concepts, having a conceptual discussion about its value for conceptual discussions is just a moot point.
And I'd say this with the "scienticist" folk in mind: you know, the people who say that "everything that can be known can be known through science" -- a statement that's self-negating because you can't know science with this standard.
Well, I am not a "scienticist" folk myself, and I´d prefer to have them defend themselves - but as far as I am familiar with their line of reasoning they don´t say "everything" (as in "everything" - including science itself).
I mean, these guys are not idiots.
I'm just pushing it to reason -- maybe from a "hope" to deflate reason as some magical end-all deal, as many rationalists and budding thinkers are often prone to holding implicitly or explicitly.
Well, I am not one of them - so apparently I am not part of the target group.
But just another thought: If I remember correctly, you are in the helping/conselling business, correct? Do you think it is a good idea to simply deflate someone else´s most dear ideas? Isn´t that merely destructive? Don´t you - instead - try to seduce people by offering a more beautiful approach?
IOW, there's something humbling *and* liberating about knowing, as you say, that systems are self-contradictory.
Again, just to clarify: I neither said nor meant to say that systems are "self-contradictory".
I do not really know what would be humbling and liberating about knowing such obvious and trivial facts that no system can justify itself by its own means.
This means that our systems are based in something more than themselves: which goes back to intuition, axiomatic stuff, etc.
Well, firstly reason
is axiomatic (as the logical problem of being unable to tackle it without employing it clearly shows).
Secondly, every other axiom or system (intuition, faith, whathaveyou) comes with the same problem. So there.
And...I've admitted openly to begging the question (see the logical ramblings), but I fail to see how I'm being inconsistent. I've said there's a reductio ad absurdum type of contradiction between the logical conclusions of "using reason when questioning reason is begging the question" and "I'm pointing out this by using reason, and so begging the question." It's not *me* being inconsistent, but the *very nature of the self-contradictory nature of the systems you're talking about* that has a sort of inherent inconsistency.
No, it´s your unfounded expectation (namely that a system should be able to justify itself by its own means - an expectation for which there is no rational nor logical basis) that creates an inconsistency between your expectations and the system in question.
I haven't created a loss-loss situation; I'm revealing the loss-loss nature of the limitations of reason and by extension any system. The fault lies in the stars, dear Brutus...
No, the "fault" lies in your unfounded expectations.
And I do think this is a useful thing to think about (although, remember, the OP was intended as a thought experiment), given that it's revealing the reasons behind (or if you prefer, "reasons" behind) the limitation of reason rather than just saying that systems are self-contradictory.
Again: I am not saying that systems are self-contradictory. You seem to be superimposing your expectations upon my statement here.
But whatever. If this is such a great discovery for you - enjoy it!
