This does not mean that a distinction between simple and complex concepts is of no use. In addition, their inappropriate use can cause problems, as seen also with linguistic, racial, or religious groupings, and as is well known this type of problem is aggravated by absolute or fundamental beliefs. This is a basic consideration if one wants to avoid MIR-belief. We do not start from sensations but from structuring experience. The dichotomy is secondary, I would think.
Similar considerations apply to the other dichotomies.
This is a question of tool elaboration, for instance by means of quantification without or with the aid of numbers. Finally, I want to emphasize again that these various remarks do not preclude my general agreement with the author's view.
