Quote:Dualism has said that there are two 'substances' in the world, like mind and matter.
But like 'subjective, objective', I have no reason whatever to consider them as related or opposed. There is simply no common ground. So on what basis do I count two and say "here is 'dualism'?
But why must you consider them as opposed? Dualism in Descartes does only mean that there is a substance named "soul" that is not physical - by that he intended "extension" - and another substance, the "body" that was physical (extension).
They are not opposed but different. And, this is the main point, they are all that exists.
The problem with this dualism is in the fact that it was not enough to Descartes. He wanted to discover how did the soul interact with the body. And there starts the problem: in order to have interaction we must find a common framework. He couldn't solve the problem (in my opinion there is no solution, because the problem in itself is false).
As you say, two different things do not make dualism. But if those two different things represent all that is and exists, and if they have different nature, then we have the cartesian dualism.
Objective and subjective, in my point of view, have nothing to do with that kind of dualism. They only represent two different perspectives about a consensual reality.
