Reality is perception Human reality is full of physical objects, but the way humans perceive these objects is completely objective, depending on the person and their senses. The perception of physical objects cannot occur without other objects that allow us to perceive these manifestations in the first place. When a sentient being recognizes that he "exists in a world of physical objects," he also confirms that his sensory perception functions to an extent that allows him to reason, even to a small extent, about his physical existence. What is a physical object? Does a physical object have to be something you can see, touch, hear, taste, or smell, or can a physical object exist without anyone being able to confirm its existence? Is a fly's sensory perception wrong just because it has more than 1000 eyes, or is the way humans see the world wrong because we don't? A blind person can still help a person distinguish a color because no perception is ever totally interpreted by a single sensory organ. Many other animals on earth don't rely on sight alone for information about their world. For example, fish in totally dark areas of the ocean have no eyes and yet can still move through the environment by sensing ripples in their area with special sense organs on their body. It seems that every year birds use the earth's magnetic lines to navigate south during the winter. It would be foolish to say that all sensory perception in the world is cautious and is exactly the same for all creatures. All animals on planet earth live in a hermeneutic spiral, which means we all live in the past. Human beings, like other animals, can perceive a cause only after it has produced an effect. We start from the assumption that if we perceive an effect there must therefore be a cause, which leads to a naive realism of perception. Furthermore, with sensory perception there is a large amount of extraneous information, of an emotional and ideological nature, which causes interference in how we interpret the information received. This misinterpretation can occur from the moment an action is performed to the moment we seem to perceive it. This can be seen for example when during a baseball game the batter hits a home run and only after a second or two you hear the crack of the bat on the ball. This can be explained because the speed of light that allows the batter to be seen hitting the ball is much faster than that of light
