Then we can conclude deepthot would have liked Descartes to state, "I experience life, which I couldn't do if I were a well-designed robot. Therefore, I am really real!"
We could have only come to such a great epiphany at philosophyforum.com.
Well, robots are really real, too (I think). Or they will be soon.
I'm not aware of any robots that can experience life.
We don't say modern robots have lives, do we?
Descartes said, "I think, therefore I exist", not, "I exist, therefore I think". Robots exist (or soon will).
Robots do exist.
In the human perspective truth is valid, mostly in natures case it is theory. Truth cannot be proven by the human eye nor can the human eye be trusted.
A well-designed robot? But, of course, the robot is real.
