The concept of “pragmatism” is one of arrogance. It presupposes that the proponent knows that his course of action will result in others causing the effect he claims.
In no cases can he, or does he, know this fact. So the claimed “Pragmatist” is actually a mere confession of arrogance.
It is the arrogant boast of a person who claims to know the motivations of all, the priorities of all, and the intricacies of every person’s individual situation.
That is a lie, and therefore the “pragmatist” is a liar.
