ABSTRACT
It misleads in a further respect. The physical tokens of any functional kind are typically manufactured to meet our functional specifications and typically there is no intelligible question of whether our functional concept is adequate to the behavioral reality the manufactured object displays. No one feels a need to evaluate our concept paring knife, for example, in order to see if it lives up to the structural and behavioral reality of real paring knives. The onus of match is entirely in the other direction. Casting FP kinds as functional kinds implicitly portrays them as having a similar “authority” and empirical “invulnerability.”
