Fact vs. Opinion

Okay so here's a little dip into some psychology. What constitutes as fact and what constitutes as opinion? Let's start with fact.

FACT - noun: meaning a verifiable truth or reality.
So many places to start... Lets start with the phrase "a verifiable truth". Verifiable can mean a hundred different things and it can also greatly depend on the situation. Take gravity for example: we are unafraid to jump because we believe that we will come down due to the earth's gravitational pull. However how can we be 100% positive that this law will always be in-tact? We can't be. But we trust that science is correct because in our own personal reality we experience that it is an accurate "fact" every day. So let's assume for now that "verifiable" simply means information or knowledge that has been tested multiple times with the same outcome, thus becoming a commonly known "fact".

Seems rather straight-forward on the surface right? Well here comes the word that contradicts the entire meaning of the word "fact".

OPINION - noun: belief.
....Wow. How incredibly vivid of you, Dictionary.com.... But this word does describe the essence of what an opinion is incredibly well. An opinion is, essentially, a belief held by an individual based on their own personal reality. But here's the thing: how can one person's personal reality be exactly the same as another's? It's virtually impossible. This is what differing opinions stem from. It seems that the whole idea of what an opinion is contradicts the idea of what fact is completely. Consider the picture below. One may see the profiles of two figures looking at each other while another may see a vase. And who knows - someone else may see something different than either of those. But is one statement more correct than the other? Are both facts? One may say that they are because the majority of people that see this photo see either two profiles or a vase. But of course, that is their own personal reality. So it cannot possibly apply to every single human that sees this image. Is it still fact?

There is so much to be said about why fact and opinion are a mystery. At the end of the day I think that facts are all, by this logic, an opinion in their own way. Personal reality determines one's perception about the world and everything in it/about it. What is fact to one human may be opinion for another and vice-versa. But of course, that's just my personal opinion. ;)
