can see colors, images, etc. that are accurate when they have NDEs (Near Death Experiences). "There are more things in heaven and Earth, Horatio, / Than are dreamt of in your philosophy". I wish we had the tools and minds available to answer so many of these questions that we have.

understanding? We need a new science of consciousness that helps us understand the magic of being.

when one begins to delve into the relationship between the conscious expectations of an observer and the reality that is observed. The whole arena of "Quantum Retro-causality" shows us that in the realm of "objective reality", the events one thought one measured may be altered by subsequent events.

Pff...


I could have told them that 40 years ago when I was a college freshman reading Carlos Castañeda and occasionally dipping into some LSD-25 on the side.

I have never seen God when I tripped but I understood a lot about certain things. Unfortunately, the brilliance that I had was short lived but very much real. In fact I had such innate knowledge about a particular subject for a History paper in college that I breezed through it and ended up with an A. When I read the paper when I got it back I barely understood what I had written, way above my ordinary level of writing. I even asked the teacher if he made a mistake on my grade. I got a C on my next paper, which I wrote while straight. I guess this isn't a good lesson to teach the kiddies.

Our senses are our reality. There are things our senses aren't sensitive enough to detect but if those things began to affect us, they become our reality too.

Our senses provide the inputs that are our perception of reality and our brains construct a model of that perceived reality. Perhaps we agree on that? But while we all have our own 'reality models' in our brains, that is not 'reality', it is a model of reality. There is an objective external reality. We can, by carefully constructing testable hypothesis and conducting experiments testing those hypothesis, understand facts about the external reality we all live in.

...who taught a course that overlapped biology & physics. Maybe even a bit of philosophy and sociology.

First day, he'd put an apple on the table and have us assert what the reality of the object was.

"It's an apple" the first student would inevitably say.

So the prof would repeat this but add an additional word, "So, to clarify: it's a whole apple?" as he turned it around to reveal it was only a half an apple.

Everyone would chuckle with that feeling of, "Aw, you got me, I see where this is going".

"It's red" another student would say. To which he'd cover the apple and hold up different red cards; the student had to pick the one that matched the red of the apple without seeing the apple. Then he'd ask another student who often picked a different red.

And so on, his point being that although there was no doubt that objectively a certain object existed on the table, each of us perceived it and internalized it very differently.

By the end of that first segment he had everyone in a sense of wonder that our human senses, nervous systems and brains could communicate with each other accurately at all.

Then he'd take out a set of calipers. A scale. A color meter. And we quickly learned that by using standards and objective tools we could indeed accurately communicate the same reality to one another.

"This," he would say, "is your introduction to science".

We know we only sense a small sliver of reality. Some animals sense light and sounds that humans can't.
There is nothing inherently 'red' about light with a wavelength of 700nm. It's just one of a continuum of wave lengths that includes radio waves which have no color assigned to them.

We have machines that can sense and assign 700nm to a particular wavelength but we don't say that the number IS the light. It's just a construct we created that allows us to calculate aspects of light.
Same with the color red. It's a construct our mind creates that allows us to distinguish one wavelength from another.

We have no direct perception of reality. Just codes our minds create to allow us to distinguish some limited aspects of reality so we can interact and survive.
