Primary vs secondary quality distinction
The primary/secondary quality distinction is a conceptual distinction in epistemology and metaphysics, concerning the nature of reality. It is most explicitly articulated by John Locke in his Essay concerning Human Understanding, but earlier thinkers such as Galileo and Descartes made similar distinctions.
Primary qualities are thought to be properties of objects that are independent of any observer, such as solidity, extension, motion, number and figure. These characteristics convey facts. They exist in the thing itself, can be determined with certainty, and do not rely on subjective judgments. For example, if a ball is round, no one can reasonably argue that it is a triangle.
Secondary qualities are thought to be properties that produce sensations in observers, such as color, taste, smell, and sound. They can be described as the effect things have on certain people. Knowledge that comes from secondary qualities does not provide objective facts about things.
Primary qualities are measurable aspects of physical reality. Secondary qualities are subjective.

Locke's distinction between primary and secondary qualities
To: Scott B. From: Geoffrey Klempner Subject: Locke's distinction between primary and secondary qualities Date: 28th April 2009 11:15 Dear Scott, Thank you for your email of 21 April, with your essay in response to the University of London Modern Philosophy question, 'Why did Locke think it important to distinguish between primary and secondary qualities?' Although the question doesn't state this, implicit in the question is the defensibility or otherwise of the primary/ secondary quality distinction as such.
electronicphilosopher.blogspot.com/2013/02/lockes-distinction-between-primary-and.html
How does Locke distinguish between primary and secondary qualities? Is he right to think that there is such a distinction?
This essay firstly examins Lockes definitions of what an Idea is and then discusses what a Quality is. There is then an explication of what the Primary Secondary Quality distinction is.

thethoughtdock: The Primary-Secondary Quality Distinction (Locke)
Our first official topic post! This post is primarily for discussion of the Primary-Secondary Quality distinction, though of course spin-off discussion is welcome (and bound to occur)!I'll go ahead and start things off, with a brief description of primary and secondary qualities. Primary qualities are properties of an object that can be characterized--nearly enough--in mathematical terms, particularly geometrical terms: length, depth, breadth, shape, location, and motion.

Philosophy Explained: Primary and secondary qualities
The distinction between the primary and secondary qualities of objects was an important theme within British empiricist philosophy, the three key proponents being John Locke, George Berkeley and David Hume. Locke sets out the distinction in his 'Essay Concerning Human Understanding'.
