Reply To: Cogito Ergo Sum

It’s a siman to existence in whatever manner you define existence. All Descartes is really saying is that while a a chair might not really exist – you are imagining/hallucinating/some other form of cognitive distortion – the same cannot be said of your own existence, because if you didn’t exist then there wouldn’t be anyone to do the imagining/hallucinating/distorting. If you want to say that we only exist as part of ???”? then it is a proof that that part of ???”? exists. I’m not sure how you are using this to answer the bechira vs. yedia stirah, and in the (at least) five-way machlokes rishonim on the matter, I don’t think any of them used Descartes as the answer.
