Religious belief can be a marvelous thing, It can give strength in times of trouble, comfort in times of grief, and direction in times of confusion.
It can also be the source of unspeakable hubris.
My own beliefs do not hew to the traditional, although I am convinced that what we see in the here and now is only a minuscule portion of a much greater reality. I do not believe that we are a species specially favoured by God, nor do I subscribe to the anthropomorphic notion of deity. I do believe that we live in a universe of potential, a potential expressed through the mechanism of evolution which I see as an ultimate expression of the transcendent. Sadly, it seems we have squandered that potential.
No one can know the ultimate truth, but it is those who claim such knowledge that I regard as especially dangerous. Those who see humanity as the supreme expression of creation often fail to approach that belief with humility, instead embracing a hubris suggesting that our 'dominion' (not stewardship) over the rest of nature comes with special entitlements. Consider where that has gotten us: wars, crusades, jihads, genocides, environmental degradation and destruction, overpopulation and climate change.
All of which calls for a reality check. And who better to provide it than the late, great George Carlin, an unsparing critic of arrogance, entitlement and presumption. His take on the Earth is both sobering and instructive, and should give the smug some pause, if only they come down from their certitude. I especially like his reflection on our serendipitous appearance and development on this planet.
If you are pressed for time, I recommend especially the insghts Carlin offers in the first five minutes of the following:
