 Like Wittgenstein, but predating him considerably, Lipps argues in his 1907 article “Das Wissen von fremden Ichen” that the inference from analogy falls fundamentally short of solving the philosophical problem of other minds. Lipps does not argue against the inference from analogy because of its evidentially slim basis, but because it does not allow us to understand its basic presupposition that another person has a mind that is psychologically similar to our own mind. The inference from analogy thus cannot be understood as providing us with evidence for the claim that the other person has mental states like we do because, within its Cartesian framework, we are unable to conceive of other minds in the first place. For Lipps, analogical reasoning requires the contradictory undertaking of inferring another person’s anger and sadness on the basis of my sadness and anger, yet to think of that sadness and anger simultaneously as something “absolutely different” from my anger and sadness. More generally, analogical inference is a contradictory undertaking because it entails “entertaining a completely new thought about an I, that however is not me, but something absolutely different” (Lipps 1907, 708, my translation).
