Sensory Qualities — SPOTM Account
What Are Sensory Qualities?
Sensory qualities (color, sound, taste, smell, heat/cold, texture as felt, etc.) are the specific forms in which the senses present the world to consciousness. They are the way entities and their attributes appear to a perceiver with a particular kind of sensory system.
Are They Real?
Yes. They are real. They are not hallucinations, arbitrary inventions, or mere subjective projections with no basis in reality. They are causally produced by the interaction between the external object and the sense organs.
Where Are They Located?
This is the key issue. The proper answer is:
Sensory qualities are not in the object alone, nor are they in the mind alone. They are aspects of the object-as-perceived.
More precisely:
- The object possesses certain attributes and causal powers (surface molecular structure, capacity to reflect certain wavelengths, vibrational properties, chemical composition, etc.).
- The sense organ and nervous system possess a specific nature that responds to those attributes in a characteristic way.
- The resulting sensory quality (redness, sweetness, middle-C, warmth, etc.) is the form in which that causal interaction is registered by consciousness.
Thus:
| Claim | Correct? | Explanation |
|---|---|---|
| Sensory qualities exist in the object independently of any perceiver | No | “Redness” as experienced does not exist in the apple in the absence of a visual system. |
| Sensory qualities exist only in the mind and have no relation to the object | No | They are caused by the object’s attributes; they are not free creations of consciousness. |
| Sensory qualities are the object-as-perceived (the form of awareness of the object) | Yes | This is the accurate description. |
Philosophical Formulation
Sensory qualities are relational yet objective.
- Relational: they depend on both the object and the means of perception.
- Objective: once the nature of the object and the nature of the sensory system are given, the quality is determined by reality, not by the perceiver’s wishes or choices.
This is why different species (or humans under different conditions) can perceive the same object in different forms while still being aware of the same object. The object is one; the forms of awareness can vary.
Contrast with Common Alternatives
- Naïve realism sometimes treats the quality as existing in the object exactly as perceived, independent of the senses.
- Subjectivism / strong idealism treats the quality as purely mental.
- Classical “secondary qualities” views (Locke and others) often place the quality only in the mind while leaving “primary” qualities in the object, creating a problematic split.
- SPOTM / Objectivist view: The quality is the form in which the object is perceived. Both object and form are acknowledged without reducing one to the other.
Short Answer
Sensory qualities are real. They are not in the object alone and not in the mind alone. They are the object-as-perceived — the specific form in which reality is presented to consciousness through the senses.
In addition:
Sensory Qualities — Expanded Explanation
1. Core Idea Restated
Sensory qualities (redness, sweetness, middle-C, warmth, smoothness, etc.) are the forms in which we perceive the world.
They are not the objects themselves, and they are not pure mental inventions. They arise from the causal interaction between:
- Attributes of the external object, and
- The nature of our sensory systems.
The result is the object-as-perceived.
2. Why This Matters Philosophically
This view avoids two opposite errors:
Error A – Naïve “qualities are simply in the object” If redness existed in the apple exactly as we experience it, independent of any visual system, then creatures with different visual systems (or humans under different lighting) would be perceiving something false. This leads to unnecessary skepticism.
Error B – Subjectivist “qualities are only in the mind” If color, sound, and taste were pure creations of consciousness with no real basis in the object, then perception would lose its status as contact with reality. This collapses into a form of primacy of consciousness.
The SPOTM position holds the middle (and more accurate) ground: the quality is real as a form of awareness of something that exists independently.
3. Additional Important Points
A. Primary vs. Secondary Qualities Distinction Traditional philosophy (especially Locke) divided qualities into:
- Primary (shape, size, motion, number) — said to be “really in” the object
- Secondary (color, sound, taste, smell, heat) — said to exist only in the mind
SPOTM does not accept this sharp metaphysical split. Both kinds of qualities are perceived in a form. Shape is also perceived in a sensory form; it is not formless. The difference is one of degree and causal complexity, not a difference in whether the quality is “really out there” versus “only in here.”
B. Relational yet Determinate Once the object and the sensory system are given, the resulting quality is fixed by nature. A normal human visual system under normal conditions will see a ripe tomato as red. The relationship is lawful, not arbitrary. This is why sensory qualities can serve as evidence.
C. Illusions and Variant Conditions Do Not Invalidate the Senses When a stick looks bent in water, the visual system is correctly registering the refracted light. The error occurs only if we judge that the stick itself is bent. The form of perception has changed because the causal conditions have changed; the senses are still functioning as they should.
D. Species Relativity Is Not Relativism A bee, a dog, and a human may perceive the same flower in very different sensory forms. This does not mean there is no objective flower. It means each perceives the flower by means of its own sensory apparatus. The object remains one; the forms of awareness differ.
E. Implications for Evidence Because sensory qualities are causally grounded in the object, they can function as evidence. The fact that we perceive an object as red, solid, or high-pitched gives us real information about its attributes, even though that information is delivered in a species-specific form.
4. Short Formulation
Sensory qualities are real relational phenomena. They exist as the way a given type of consciousness is aware of an independent object. They are neither locked inside the object with no reference to a perceiver, nor locked inside the mind with no reference to the object. They are the object-as-perceived.
This understanding preserves both the objectivity of perception and the reality of the external world.
