10 weeks is pretty short! Sounds like a good challenge. I was assuming 16 weeks while trying to lay out a simple curriculum last night, and I got the following structure:

I. The Problem of Doubt

• Week 1: What are we doing here?
• Week 2: Case studies in ignorance and error
• Week 3: Case studies in irrationality and arbitrariness
• Week 4: Evaluating arguments
• Week 5: Descartes and certainty
• Week 6: Reasoning with uncertainty

II. The Problem of Death

• Week 7: Test case: The immortality of the soul
• Week 8: How to want to change your mind
• Week 9: Test case: The self
• Week 10: Learning how to learn things

III. The Problem of Life

• Week 11: Vagueness, ambiguity, and semantics
• Week 12: Meta-ethical confusions
• Week 13: Rationality and decision theory
