I disagree. Reason gives us the Calculus. Can it be said that there are British, American, Indian, Arabian or Chinese mathematics? Is not Calculus the same, no matter the country in which it is studied? The beauty of science is that it proves--whether in Bangkok, Baghdad, Singapore, Dehli, Tokyo, London or Boston. The problem with so-called belief in what may be called, the metaphysical, is that cultural bastardizations are inevitable.

Community coalesces around shared experiences and beliefs and objectives. Religion uses dogma and ritual to support that. Critical thinking isn't about experience, it is about thoughts, and so is inherently a private and not collective activity. However, there are lots of ways to form community. My wife and I are together because, among other things, her experience of growing up with a crazy mother enables her to understand my experience of being married to my crazy first wife, and vice-versa, and her being widowed helps her understand me being widowed and vice-versa. We formed a relationship around those and other shared experiences. No mysticism needed.

I don't see how reason is itself a source of division. I would expect that in the main, reason would lead to intersubjective truth which is something that all people deploying reason can agree on. Water boils at 100 degrees Celsius, period, end of story. There's no room to disagree on that. There is of course no such thing as 100% objectively provable truth, so there are a lot of things that aren't as clear cut as the boiling point of water at sea level. But beliefs formed from reason and logic are going to be FAR more consistent than beliefs randomly made up and subscribed to by various conjurers. They also should not be argued based on what people feel or wish to be true, but on what IS true.

I have to agree , there seems to be truth in this statement . Tell anyone what they don't want to hear and reason goes out the window .
