Did you get that feeling reading these books?
McCarthy expands on this theme slightly in a rare interview: McCarthy likes the scientists at the Institute for a simple reason: The stuff they explore, like his writing, cuts to the bone.
“If it doesn’t concern life and death,” he says, “it’s not interesting.” 
If you're looking for lighter (but still excellent) storytelling on similar Western/survival themes I'd suggest the Border Trilogy  by McCarthy. My high school English teacher had us read these instead of Blood Meridian (his favorite book of all time) because they're much less violent. You won't get the full experience, though, as some of McCarthy's characters are genius because of their depravity, violence, and seemingly chaotic natures.
I really don't see what ppl like about the BT.
Not gonna lie: Blood Meridian deals in some very grim and violent subject matter. There are no heroes in that story. Its about a gang of scalp hunters (the Glanton Gang. They actually existed if you can believe it...) so I'll leave you to draw your conclusions about what a story like that would entail. The way McCarthy makes those types of scenes digestible is by almost always describing them in the past tense. You the reader come upon them after they happened. He also writes with a detachment to the event and speaks of some downright unspeakable acts almost matter of factly. I am pretty squeamish and I could handle it so you'll probably be fine because of that.
The Road I found harder to read than BM. Its less violent (although there are a couple spots that get pretty gruesome) but just unrelentingly bleak and grim. I needed to lie down after reading it. Again his detachment from the events happening make it bearable. Worth it IMO.
Assuming you haven't read them, I'd recommend digging into All The Pretty Horses or No Country For Old Men. Both are incredible stories that have the same scenes of elemental good vs evil that crops up in McCarthys work over and over again but are less... intense.
> . . . and he saw men lanced and caught up by the hair and scalped standing and he saw the horses of war trample down the fallen and a little whitefaced pony with one clouded eye leaned out of the murk and snapped at him like a dog and was gone. . . And now the horses of the dead came pounding out of the smoke and dust and circled with flapping leather and wild manes and eyes whited with fear like the eyes of the blind and some were feathered with arrows and some lanced through and stumbling and vomiting blood as they wheeled across the killing ground and clattered from sight again. Dust stanched the wet and naked heads of the scalped who with the fringe of hair below their wounds and tonsured to the bone now lay like maimed and naked monks in the bloodslaked dust and everywhere the dying groaned and gibbered and horses lay screaming.
I read The Road when I was probably 22 or 23. I now have a son who is six (I'm a man, for context), and I suspect that if I were to re-read it, I would likely weep uncontrollably for an hour or two, and then spend the next several months sporadically crying and clutching my son. It is a hard, hard read, and even harder (I assume) if you're a parent.
That being said, it's also a masterpiece of a book. Ultimately it does have a glimmer of optimism, it's just a really rough time getting to that optimism. I don't regret reading it, but once is enough, for now.
I read it again when my son was 4 months old. That's when I finally understood, at a visceral level, what it means to carry the fire. I think we're both going to be better because of it.
I will read the book one more time after my dad passes.
That's what life really is, when you strip away the conveniences. The real horror is to realize that for many people in history (and even now) reality has been worse.
I haven't read Blood Meridian yet, but Child of God (another McCarthy novel) definitely lacks the optimism of The Road.
As for this article, I think that the subconscious fascinates almost everyone. The reason we have psychology (in my opinion, of course) is that it's apparent to almost all of us that there's something going on under there.
Everyone has anecdotes like the one mentioned in this article, where a solution to a problem appears in a dream or pops into someone's head immediately after waking.
I think you should read one of them. If you want, I'll read The Road (or any other one) while you do and we can talk about it. Someone has to carry the fire.
It presents man's intellect as the apotheosis of 4 billion years of pain, suffering, death, and destruction. Man as the ultimate practitioner of the ordering principle of the universe: War
But it is truly horrific.
I would say Suttree is a lighter (relatively speaking) read.
The old musty album with its foxed and crumbling paper seemed to breathe a reek of the vault, turning up one by one these dead faces with their wan and loveless gaze out toward the spinning world, masks of incertitude before the cold glass eye of the camera or recoiling before this celluloid immortality or faces simply staggered into gaga by the sheer velocity of time. Old distaff kin coughed up out of the vortex, thin and cracked and macled and a bit redundant. The landscapes, old backdrops, redundant too, recurring unchanged as if they inhabited another medium than the dry pilgrims shored up on them. Blind moil in the earth's nap cast up in an eyeblink between becoming and done. I am, I am. An artifact of prior races. [...] What deity in the realms of dementia, what rabid god decocted out of the smoking lobes of hydrophobia could have devised a keeping place for souls so poor as is this flesh. This mawky worm-bent tabernacle.
>He was half way back up the caldera to his truck when something made him stop. He crouched, holding the cocked pistol across his knee. He could see the truck in the moonlight at the top of the rise. He looked off to one side of it to see it the better. There was someone standing beside it. Then they were gone. There is no description of a fool, he said, that you fail to satisfy. Now you're goin to die.
The pistol mentioned was taken from a dead drug dealer. The someone next to the truck would drive most of the rest of the story.
