“The Dematerialization of Matter”, Norwood Russell Hanson1962 (, ; backlinks)⁠:

  1. The philosophical version of the primary-secondary distinction concerns (a) the ‘real’ properties of matter, (b) the epistemology of sensation, and (c) a contrast challenged by Berkeley as illusory.

    The scientific version of the primary-secondary distinction concerns (a’) the physical properties of matter, (b’) a contrast essential within the history of atomism, and (c’) a contrast challenged by 20th century microphysics as de facto untenable.

  2. The primary-secondary distinction within physics can be interpreted in two ways: a. it can refer to content; eg. ’Matter has the properties of mass, shape, density… etc.—it only appears to have the properties of warmth, fragrance, etc.’ Or, b. it can refer to form; eg. ’Whatever properties our best theories accord to primary matter, eg. electrons, these are by definition primary. All other properties of, eg. macromatter, are derivative’.

Concerning 2.a., this interpretation is simply false when 17th, 18th, or 19th century values for the property-variables are introduced.

Concerning 2.b., this either uninformative or misleading.
