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.
