We have diverged so far off the correct path.
In order to be fair to the thread-starter's title question, let us discuss the meaning of the word "freedom." What does it mean to be "free?"
Instinctively, many people understand the word in its most absolute sense -- i.e. without any restrictions of any sort whatsoever. However, even a 10-second reflection will reveal that that interpretation is childish. How can one be free of everything? Free from gravity? Free from hunger and thirst if one does not consume meals? Free from rules governing inter-personal relations?
No, the expression "free" is commonly used
with respect to specific constraints that may affect a person. For example, a prisoner will declare himself "free" after serving his sentence, while a hospital patient will declare himself "free of cancer" after chemotherapy treatment. In both cases, the constraining condition is identified. Therefore, I think the title of this thread -- "Are free thinkers really free? -- is defective
in so far as it fails to mention the specific constraints that free thinkers are supposedly liberated from.
Back to our above example. A cancerous prisoner may tell his relatives on the phone, "I am free."
The relatives may reply,
"Free from what?" They know that he has been treated for cancer, and they know he has had a parole hearing, and they hope the best for him on both issues.
"Are free thinkers really free?"
"Free from what?"
Specifics would lead to a much more sane and productive discussion than meandering around forever.
As I said before, free thinking is specifically concerned with liberation from certain constraints, namely:
* tradition. Is something right simply because your forefathers and all the tribes / races around you believe it is right?
* Religion. The whole world is a melting pot right now, so this point is not as strong as it was 100 years ago, when -- for example, the Pope's word was "infallible." However, we are now
free to question whether humanity is 6000 years old (many people expected Jesus to return circa 2000, with a final "day" (=1000 years) of "God's reign on earth" to last from year 2000 to 3000).
We are free of such superstitions.
* authority. A free-thinker should not be worried about political-correctness, and should not align his research in such a manner as to please powers-that-be.
* popular culture/fashion. I have personally had this argument with people who come and tell me, "You know, in the academic world, it is
no longer fashionable to think a-b-c. We are
following new trends." Such a statement drives me wild. Fashion has no place in the intellectual world!!! It is a constraint to logical thought and clear observation.
* prejudice. If you come into an argument "knowing" the conclusion (a common trait among all religious people worldwide), what happens is that you simply look for evidence to fulfill your pre-knowledge (eg people who see Christ's image on pieces of cloth). This pre-determined-conclusion behaviour should be left to deceitful lawyers who want their clients off the hook by hook or by crook. A true free thinker should not care where an argument goes.
A good example is the prejudice that "in every event, there is a subject and an object." This gives rise to a fiction like "it rained." What is this "it" that rained? Where is this "it" hiding? In the skies? In outer space? Can it move forward and identify itself? Next thing we have fictions like "jinis", "soul", "evil spirits", "angels", etc, etc...
A true free-thinker will even accept the possibility of the existence of god(s) and other world(s). All he/she asks is, "Demonstrate it." Of course, at this point, Bibles/Korans are unleashed and the discussion dies a natural death.
* some human constraints to free-thinking are much more difficult to identify, and are not social like the ones listed above. For example, man is a creature of habit. But some of our habits are so ingrained in us that we may never ever examine them with an objective eye. We are not even conscious of them. Yet they interfere with clean logic.
* Language is another barrier. Language is often used to describe, but very often language becomes an imperial force, dictating what we think.
* Notation/alphabets are other barriers to free thought. In the computer world, they don't use base-10 but the famous base-2 (binary). Base-2 also has its limits.
"Are free thinkers free from authority?" -- then we could discuss how certain thinkers do so much to produce ideas that are pleasing to the powers-that-be, while hiding bad-but-true ideas.
