Understanding Descartes's Dream Argument

Paper Summary:

The "dream argument" may have been a truly-lived expression of doubtfulness during Descartes's era. This paper notes why Descartes and his contemporaries may have been truly puzzled, given the state of scientific understanding at that time. Today, one cannot even get to the point in which proving or refuting Descartes's dream argument would make any sense. One cannot simply lift the dream argument out of those circumstances and transplant it to our times. The paper shows that what may be appropriate is to look at computer technology today and ask whether computers can think, dream, and be deceived by their dreams.

From the Paper:

"One can first begin with the question of whether computers can really play chess. Over thirty years ago it would have been very apparent that chess game software (and the corresponding hardware) had a challenging time competing with someone who was a decent chess player. When the question was asked over thirty years ago, it was possible to answer the question in the negative by way of showing the essential differences between how a human makes a move in chess versus how a computer performs the same operation."
