Question

Read the excerpt below and answer the question.

It remained, then, to conclude that it was put into me by a nature truly more perfect than was I and possessing in itself all the perfections of what I could form an idea—in a word, by God . . . for if I had existed alone and independent of all other, so that I had of myself all this little whereby I participated in the Perfect Being, I should have been able to have in myself all those other qualities which I knew myself to lack. (Discourse on Method)
The best inference from the passage is that God must exist because otherwise Descartes, as an imperfect being, ________________________.
would not exist
would be God
would lack no advantageous qualities
would have no knowledge of the idea of perfection
The answer to this question is NOT B, I feel like it's D but I just want a second opinion

Answer 1

Because of the part of the passage that states,

"For if I had existed alone and independent of all other, so that I had of myself all this little whereby I participated in the Perfect Being, I should have been able to have in myself all those other qualities which I knew myself to lack."

I believe that you are correct and the answer is D. The best inference from the passage is that God must exist because otherwise Descartes, as an imperfect being, would have no knowledge of the idea of perfection.
