Explain thoroughly Descartes’ own reasoning for adopting the position of substance dualism.

In your essay, explain thoroughly Descartes’ own reasoning for adopting the position of substance dualism. Individuals like Churchland disagree with this view, opting for a materialist position about the nature of the mind and self. Are you more sympathetic to Descartes or Churchland with respect to this issue? Take a position on this question, being sure to offer arguments to support your view, entertaining objections to your arguments, and offering a reply showing why your position still stands, taking the stance of more of a materialist perspective like Churchland. The essay must include at least one peer-reviewed, external (outside of course material), academic source, effectively. Use Google Scholar for the source.
