Thinking vs Cognition (Arendt)
Arendt's distinction between thinking — the goalless activity of following threads of meaning — and cognition — goal-directed problem-solving — which identifies what AI systems perform abundantly and what they categorically cannot do.
In The Life of the Mind, Arendt carefully distinguished three mental activities: thinking, willing, and judging. Thinking she defined against cognition. Cognition is the activity of the intellect aimed at knowing something — solving a problem, achieving a result, establishing a truth. Thinking has no such goal. It is the activity of turning things over, following a question where it leads, sitting with meaning that does not resolve into solution. The distinction matters for AI because the machine is a cognition engine of extraordinary power and not a thinking being at all — and the substitution of machine cognition for human thinking is a loss that no productivity metric can register.
