XII explained
Descartes explains why not everyone arrives at the same clear knowledge of the mind: because they have not philosophized in order and have failed to distinguish the mind from the body.
What happens
Descartes explains why not everyone arrives at the same clear knowledge of the mind: because they have not philosophized in order and have failed to distinguish the mind from the body. They mistakenly attribute the faculty of perception to the body, which they see and touch, and thus fail to apprehend the nature of the mind distinctly.

Key passages
“Those who have not philosophized in order have had other opinions on this subject, because they never distinguished with sufficient care the mind from the body.”
People who have not followed a proper philosophical method hold different views because they have not carefully separated the mind from the body.
Descartes attributes confusion about the self to a lack of methodical distinction between mind and body.
“they rather meant their bodies which they saw with their eyes, touched with their hands, and to which they erroneously attributed the faculty of perception”
Instead, they meant their bodies—which they could see and touch—and mistakenly thought the body itself could perceive.
The common error is to identify the self with the physical body and to wrongly assign perception to it.
