Aaaw Khandro,
(a) I knew you would dismiss Kaleko as a poet, not a philosopher. So if poets do not count as philosophers, who do? Definition from you please - by your very own by yourself - no quotes from others or just citing a name please.
(b) We are not all agreed about Einstein's reply and that we agree to take it at face value! I argued earlier that Einstein was simply being polite and "corrected" her by saying metaphysics had been superceeded by pure physics. I believe jomifl supported me in my contention.
(c) I agree with jim, Descarte's statement is very much open to question. That many things exist without thinking cannot be contested at this stage in our knowledge. Similarly jim's follow-up questioning the superiority of we humans is bang on. We are not special, "it's all in the mind, lol"
And his contention is not nihiliastic, just an unpleasant thought for many, but not me! Ask Descartes..oops you can't 'cos he's just unthinking dust, thanks to entropy.
Kindest Regards,
SIQ.
