What am I?

• a body? -- No
• "a suble air distributed through" the body? (P 222a) -- No
• "A thing which thinks." (P 222b) -- Yes

"I am ... precisely only a thing that thinks, that is, a mind, or soul, or intellect, or reason ..." (P 134b)

"What is a thing which thinks? It is a thing which doubts, understands, [conceives], affirms, denies, wills, refuses, which also imagines and feels." (P 222b; Cf P 135b, 134b)
