"Reality is a Perception"

"What we experience may not be real, but it is still what we experience, and is therefore real." Harmony Theory, chapter 9: Perceptions, by Sharaloth

Emotions are not real, but are explanations of our experience based on our limited understanding. However they are undeniably things we all feel. Not a single person can say they've never anger, sorrow, fear, love, etc. They are what we experience, and thus become real. Yet we all feel and understand these emotions differently, with countless varying degrees. These differences, caused by variation in character from person to person, cause differentiation in our reactions to our circumstances. Therefore our emotions dictate the way we see reality. If our emotions vary from person to person, and our emotions affect the way we see and react to the reality of our circumstances, then what we see is determined by our emotions. Thus reality as seen by any individual, is a biased byproduct of their emotions, and therefore a personal perception of reality.

As humans we have a limited understanding of our surroundings. We see things happen without any knowledge of their inner workings, yet we also see the inner working of things without knowing the grand scheme. A mechanic can look at a house and simply know that it stands, but a carpenter may look at a house and know of the load bearing walls, angle braces, and cross beams that make the house stand. However the carpenter can get up in the morning, start their car, and go to work. But the mechanic knows of every piece and part that allows the car to do so. We all know the Earth rotates, but we do not experience it. We all experience the sun rising and setting, but we know this isn't true. This isn't a contradiction of truths, simply varying perceptions of the world around us. We know the Earth orbits the sun, but many people have no idea that the sun (and the rest of our solar system) is orbiting a much stronger force. To us, the sun of our solar system is unimaginably large. But to the Galactic Bar, our entire solar system is barely even noticeable. It all depends on how you look at things, and what scales and standards you use.
