Single Idea 5579

[filed under theme 11. Knowledge Aims / B. Certain Knowledge / 5. Cogito Critique ]

Full Idea

It seems strange that the condition under which I think is to be valid for everything that thinks, and that on an empirical-seeming proposition we can presume to ground a universal judgement, that everything that thinks has self-consciousness.

Gist of Idea

How can we infer that all thinking involves self-consciousness, just from my own case?

A Reaction

Kant is not bothered by this, and says we know it a priori. If it is indeed an empirical proposition, it becomes an induction with one instance, which is the notorious weakness of the 'argument from analogy' to other minds. The Cogito is not empirical.

13003 The Cogito doesn't prove existence, because 'I am thinking' already includes 'I am' [Leibniz]
19334 I can't just know myself to be a substance; I must distinguish myself from others, which is hard [Leibniz]
