Twelve principles I’m taking away from recent discussions

  1. Hypotheses non fingo A: Ideas about things are not hypothesized and tested against those things so much as things are determined to be what they are by testing them against ideas. Facts are recognizable as such only because they relate with a prior idea.
  2. Hypotheses non fingo B: Cohen’s introduction to Newton’s Opticks makes it plain that Newton is not offering a general methodological pointer in this phrase. Rather, he is answering critics who wanted him to explain what gravity is, and what it’s causes are. In saying, I feign no hypotheses, Newton is merely indicating that he’s not going to make up stories about something he knows nothing about. And in contrast with the Principia, the Opticks provides a much more accessible overview of the investigative process, from the initial engagement with light, where indeed no hypotheses as to its causes are offered, and onto more specific inquiries into its properties, where hypotheses necessarily inform experimental contrasts.
  3. Ideas, such as mathematical/geometrical theorems, natural laws, or the structure of Rasch models, do not exist and are unobservable. No triangle ever fits the Pythagorean theorem, there are no bodies left to themselves or balls rolling on frictionless planes, and there are no test, survey, or assessment results completely unaffected by the particular questions asked and persons answering.
  4. The clarity and transparency of an idea requires careful attention to the unity and sameness of the relevant class of things observed. So far as possible, the observational framework must be constrained by theory to produce observations likely to conform reasonably with the idea.
  5. New ideas come into language when a phenomenon or effect, often technically produced, exhibits persistent and stable properties across samples, observers, instruments, etc.
  6. New word-things that come into language, whether a galaxy, an element in the periodic table, a germ, or a psychosocial construct, may well have existed since the dawn of time and may well have exerted tangible effects on humans for millennia. They did not, however, do so for anyone in terms of the newly-available theory and understanding, which takes a place in a previously unoccupied position within the matrix of interrelated ideas, facts, and social networks.
  7. Number does not delimit the pure ideal concept of amount, but vice versa.
  8. Rasch models are one way of specifying the ideal form observations must approximate if they are to exhibit magnitude amounts divisible into ratios. Fitting data to such a model in the absence of a theory of the construct is only a very early step in the process of devising a measurement system.
  9. The invariant representation of a construct across samples, instruments, observers, etc. exhibiting magnitude amounts divisible into ratios provides the opportunity for allowing a pure ideal concept of amount to delimit number.
  10. Being suspended in language does not imply a denial of concrete reality and the separate independent existence of things. Rather, if those things did not exist, there would be no impetus for anything to come into words, and no criteria for meaningfulness.
  11. Situating objectivity in a sphere of signs removes the need for a separate sphere of facts constituted outside of language. Insofar as an ideal abstraction approximates convergence with and separation from different ways of expressing its meaning, an objective status owing nothing to a sphere of facts existing outside of language is obtained.
  12. The technology of a signifying medium (involving an alphabet, words as names for features of the environment, other symbols, syntactical and semantic rules, tools and instruments, etc.) gives rise to observations (data) that may exhibit regular patterns and that may come to be understood well enough to be reproduced at will via theory. Each facet (instrument, data, theory) mediates the relation of the other two.
