Are the skeptics useful? So asks Hayim.
"The problem starts when the community leans too heavily in one direction. Freewheeling "metaphysics", or an exaggerated emphasis on scholarship to the detriment of other approaches of Judaism, are deplorably overprevalent in our day and age. So we need the skeptics, if only to give us a reality check on the direction our community is taking.
On the other hand, an excess in the opposite direction is even more disastrous. I, for one, would not want to be in Mis-Nagid's shoes. Overskepticism, i.e. the drive to only destroy and never build, must leave you unfulfilled and sour. I am glad to see that some still realize this."
Are you familiar with R' Kook? What you say here is pretty similar to his views. He said that atheists weren't rejecting God, they were rejecting faulty human images of God. That they were actually serving true Monotheism by keeping the faithful on their toes and keeping them from slipping into comfortable easy-thinking heresy.
What you call "overskepticism" would actually be a form of nihilism. This is the where the individual believes essentially in _nothing_. Does not believe in morals, human values, respected traditions, patriotism, progress, the future, and disbelief in religion and God go without saying.
Some nihilists even go so far as to say that there is no point at all in living (since they hold value in nothing). They only strive for the end and to help others get there too through helpful mutual destruction.
There are some who argue that the necessary conclusion of systematic skeptical thinking is the arrival at some form of nihilism. They have a point. If you keep asking "why?" you will eventually hit a wall, an axiom, that you must actively choose to accept, or not. Those that find that they cannot accept even those axioms are often lead directly to nihilism, which is really a depressing and dangerous place to be.
To note though, I do not believe that Mis-nagid is a nihilist.
I, for one, do not think nihilism is good thing. Nor do I think is unrestrained credulity. There may be a happy middle ground, but frankly, I'm not really a fan of this "faith" business at all. What I am slowly realizing though is that even while we may not like faith, it is a necessary and unentangleable part of meaningful human life.
