“It also means that cosmology doesn’t really have a well-defined concept of “now.” Or rather, the “now” you experience is highly specific to you, to where you are and to what you are doing. What does it mean to say “that supernova is going off now” if we see the light of it now, and we can watch the star explode now, but that light has been traveling for millions of years? The thing we’re watching is essentially fully in the past, but the “now” for that exploded star is unobservable to us, and we won’t receive any knowledge of it for millions of years, which makes it, to us, not “now,” but the future.
When we think of the universe as existing in spacetime—a kind of all-encompassing universal grid in which space is three axes and time is a fourth—we can just think of the past and the future as distant points on the same fabric, stretching across the cosmos from its infancy to its end. To someone sitting at a different point on this fabric, an event that is part of the future to us might be the distant past to them. And the light (or any information) from an event that we won’t see for millennia is already streaming across spacetime toward us “now.” Is that event in the future, or the past, or, perhaps, both? It all depends on perspective.”

“But as Descartes observed, even an infinitely powerful evil demon couldn’t trick him into thinking he himself existed if he didn’t exist: cogito ergo sum, “I think, therefore I am.”

“We are all regularly presented, day after day, with bad news, the worst, and I think our minds are more and more set into attitudes of foreboding and depression. But is it possible that all the bad things going on – and I don’t have to list them, for we all know what they are – are a reaction, a dragging undertow, to a forward movement in the human social evolution that we can’t easily see? Perhaps, looking back, let’s say in a century or two centuries, is it possible people will say, ‘That was a time when extremes battled for supremacy. The human mind was developing very fast in the direction of self-knowledge, self-command, and as always happens, as always has to happen, this thrust forward aroused its opposite, the forces of stupidity, brutality, mob thinking’? I think it is possible. I think that this is what is happening.”

“But is there such a thing as trauma without shame? Isn’t shame an integral part of what causes an event or series of events to become a trauma?”

“What if the problem with schizophrenia patients wasn’t that they lacked the ability to respond to so much stimuli, but that they lacked the ability not to? What if their brains weren’t overloaded, but lacked inhibition—forced to reckon with everything that was coming their way, every second of every day?”
