Perception is the physical process of certain types of objects. Perception like knowledge and conception are not objects in themselves but seem to exist as an illusion due to the continued process within an object. Once the process ends the perception ends. The final end of the perception for an object is called death.
Modern science tells us that space is energy. This makes sense with Einstein’s equation – E=mc2 – where mass and energy show a mutual and direct relationship. Since space seemingly “replaces” an object in a position it can be treated like an object. Further, nothing violates this. A “position” in space is either occupied by space-energy or object-mass. And multiple objects never occupy the same position. The proposition is, a position is occupied by either an object-mass or an object-space.
I am a philosophical realist.
The physical reality, to me, exists independently regardless of whether it is perceived or not by me or anyone else.
The evidence is that things, firstly, do not simply disappear if it is not perceived. The back of my MacBook I am typing this on is there even though I am not seeing it. This extends to everything else, the underside of the table, outside, beyond the driveway, over the hill, behind the cloud. Secondly, before I came into existence the world existed. My parents were there to bring me into the world. And their world was a continuation of mine. Go back again further enough and there would been a time when no one existed to perceive the world. It makes sense that it existed even without being perceived. Thirdly, there will be a time in the universe when everything that perceives will pass away, and the physical world will continue to exist. There is no reason why it should disappear.
This kind of thinking places us into a mode of humility. We are not special, no more or less special than anything else. But to think we are better than other things because we see this is part of the complacency of being human. It is the exact same “place” where the humility comes from. But we must learn to struggle with that, knowing we will never fully be free from this view as a collective and as an individual, if there are such things to begin with.

We often confuse sensation and perception.
Think of the camera obscura. There is nothing but light which is making the image on the wall. Or think of a video camera attached to a video screen. The camera captures the light external to it, turns it into data and turns that data in to the video image on the screen. It does not “think” about the image. It does not “have an opinion” of it. It simply reproduces it.
The eye does the same thing. It captures light eternal to it, turns it into data and reproduces that in your brain. Until then it does not “think” about the image. Thinking occurs after that data is received. That raw data is sensation. The processed data after reception is perception.
If you are still not convinced then this talk by Sheila Nirenberg about her research on the prothetic eye is an excellent real-world demonstration of what sensation and sense data is.
A track pad is a track pad is a track pad. Not.
Take the Apple MacBook Pro 2015 and the Microsoft Surface Pro 2018 – they both have touch or track pads. But on the MacBook pad is fixed. This might sound ridiculous and unusable but really it means that there are less moving parts and less likely to break. The workaround for this is an incredible haptic feedback system which taps back against your finger making it feel like some kind of movement. The illusion is simply quite amazing. The Surface Pro still uses a traditional traditional track pad. While it has become multitouch like most of today’s devices it still means it feels old. The verdict – MacBook‘s track pad is simply an experience. Unless one uses tries similar but different things one does not know the subtle differences between them. Direct experience is important, in every sense.
It would be nice if tomorrow I would woke up and a different US president was in the White House. But because there is one reality I have to be content and continue with it.
It would also be nice if I woke up tomorrow morning to find I am a world famous scholar with three important books on my resume. Again, that would not be the case. I must work for those. Sigh.
