Is Religion and Spirituality somehow to blame for the downfall of society?
The ecological and moral destruction that we see at hand?
Is religion and spirituality a symptom? Or is it a cure for human ills?
None of the above. Human nature itself is responsible for the many adoptions of forms of religion and/or spirituality -- and for how they sometimes provide some comforts and answers, and also for how they far too often engender hatreds and conflict. Human nature itself is responsible, often throught our inventions of various ideologies -- that often fly in the face of reason -- that permit us to rape and despoil the earth itself, the only home we have, and where we must survive or die out.
Spirituality, when it is seen as an effort by humans to connect with and understand our place in an often-mysterious universe, I would generally call a positive thing. But spirituality (if it really is spirituality) involves no dogma, no "truths that must be believed," and is therefore not dangerous. Only that which must be believed no matter what -- which includes not only religious beliefs but political dogmas as well -- and which humans seem all to willing to accept no matter what evidence might tell them if they looked -- that is what will lead to the worst of human experience.
And as a humanist, I have to see that only reason and the acceptance of such truths as can be evidenced will save us. I also know, however, that most humans find reason about all aspects of human experience to be very, very hard to achieve. You will understand that that makes me something of a pessimist about the long-term future of humanity on this planet. And since we have nowhere else to go, our long-term future in the universe as a whole.
