Your sense organs, like taste buds, simply detect physical or chemical stimuli. This "detection" is not your experience. Perception occurs only when the brain receives these electrical signals and transforms them into a subjective experience like sweetness, creating your reality.
We see a minuscule fraction (0.0035%) of the electromagnetic spectrum, meaning our perception of physical reality is already an abstraction. When applied to complex human behaviors, objective "truth" becomes nearly impossible to discern, as it's filtered through cognitive shortcuts and biases.
Our perception of sensing then reacting is an illusion. The brain constantly predicts the next moment based on past experiences, preparing actions before sensory information fully arrives. This predictive process is far more efficient than constantly reacting to the world from scratch, meaning we act first, then sense.
Mathematical models of evolution demonstrate a near-zero probability that natural selection would shape sensory systems to perceive objective truth. Instead, our senses evolved merely to guide adaptive behavior, prioritizing actions that lead to survival and reproduction over generating an accurate depiction of the world.
Our psychological experiences, including positive and negative emotions, are not separate from our physical selves. They are direct results of biological processes in our brain's limbic system, which evolved as an alert system.
With 10x more neurons going to the eye than from it, the brain actively predicts reality and uses sensory input primarily to correct errors. This explains phantom sensations, like feeling a stair that isn't there, where the brain's simulation briefly overrides sensory fact.
Our senses don't register static energy states. We feel acceleration, not constant speed, and heat transfer, not absolute temperature. This principle extends to emotions, which may be our brain's interpretation of internal energetic shifts, or 'energy in motion'.
The right hemisphere of the brain doesn't define a separate "you." It experiences the world as a unified whole, integrating all sensory input into one big picture. This is the neurological basis for "flow states" or feelings of transcendence, where the boundary between self and the world dissolves.
When we observe neurons, we are not seeing the true substrate of thought. Instead, we are seeing our 'headset's' symbolic representation of the complex conscious agent dynamics that are responsible for creating our interface in the first place.
Taste perception isn't fixed; it's modulated by your body's internal state. For example, highly concentrated salt water is normally aversive. However, if you are salt-deprived, your brain will override the tongue's signal and make that same taste intensely appetitive to correct the physiological imbalance.
According to neuroscientist Jenny Groh, thoughts are constructed by layering sensory experiences (sights, sounds, feelings) onto a core concept. This is why limiting distracting sensory inputs is essential for controlling your focus and preventing your mind from wandering.
