'Tis the human touch in this world that counts,
The touch of your hand and mine,
Which means far more to the fainting heart
Than shelter and bread and wine.
The shelter is gone when the night is o'er,
And the bread lasts only a day,
But the touch of a hand and the sound of a voice
Sing on in the soul alway.
Spencer Free
Perception is Inner Reality‘s organization, identification, and interpretation of signals from Outer Reality. Signals result from stimulation of the senses:
Vision involves light striking the retina of the eye.
Smell involves odor molecules reaching the nostrils.
Hearing involves pressure waves reaching the ears.
Touch involves external disturbance of the skin.
Taste involves molecules reaching the surface of the tongue.
Proprioception is the sense of self-movement, force, and body position, mediated by proprioceptors in muscles, tendons, and joints.
Intuition is the sense of acquired knowledge without recourse to conscious perception through direct access to unconscious knowledge; unconscious cognition; gut feelings; inner sensing; inner insight to unconscious pattern-recognition; or the ability to understand something without any need for conscious reasoning.
The perceptual systems of the brain enable us to see the world around us as stable, even though the sensory information is typically incomplete and rapidly varying.
Human and other animal brains are structured in a modular way, with different areas processing different kinds of sensory information.
Some of these modules take the form of sensory maps, mapping some aspect of the world across part of the brain’s surface.
These different modules are interconnected and influence each other. For instance, taste is strongly influenced by smell.
Proprioception and Intuition could be said to sense inner reality as well as outer reality.
