Classification of Sensations

The full gamut of human perception is wildly varied, some experiences forever dancing beyond the grasp of language and mathematics. But even an oversimplified account of sensation can be very valuable. So let's start crudely dividing perceptions into a handful of categories. Definitions are fuzzy. There may be gaps and overlaps. But starting from this oversimplification we progressively add more detail and refinement until we can ultimately communicate with precision and accuracy about our perceptions.

Category Examples
Visual Sensations
Any vision, sight or ocular experience that could loosely be described as grayish is called an achromatic visual sensation. Any sight that could be roughly described as reddish or greenish is called an organic chromatic sensation. And any image that could be described as yellowish or bluish is called an inorganic chromatic visual sensation.

Thermal Sensations
Strong feelings that are so hot or cold that they are hazardous are called dangerous thermal sensations. Warm or cool feelings that happen during routine human activity are called safe thermal sensations.

Somatic Sensations
Any tactile or auditory perception associated with a sense of touch, pressure, hearing or sound is called a somatic sensation.

Taste Sensations
Flavors or gustatory perceptions that are produced when a substance in the mouth reacts chemically with nerves of the tongue and palate are called taste sensations. We specifically consider sweet, sour and salty flavors. But bitter, pungent, metallic and savory tastes are other well-known examples from among hundreds of distinctly recognizable flavors.

Other Sensations
Smells, odors and olfactory perceptions. Balance and related kinesthetic senses. Animalistic perceptions like echo-location or sensitivity to the Earth's magnetic field. Telepathy, clairvoyance and paranormal abilities. A sense of humor. An eye for beauty. A feeling for the truth, or for justice, or for lots of other abstract nouns. Miracles, memories, hallucinations and dreams. The insubordinate look of love.

The words organic, inorganic and somatic are used above in ways that are specific, but perhaps slightly unusual. So let us be perfectly clear and make formal definitions for these terms as follows.

Organic Sensation $\sf{\text{Any reddish or greenish visual sensation.}}$ 13
