- Reasons for doubting mathematics
- Descartes is looking at the issue of certainty as it is understood by the mathematicians
- He finds the conclusion physiologically irresistible
- Reason 1
- The person who gets the wrong answer finds the wrong as physiologically irresistible
aswell. - If the basic of mathematical knowledge is physiologically irresistibility then it is totally
- Reason 2
- In mediations 1 and 3 he still does not know if God exists
