which two statements from discourse on method best exemplify descartes' break with aristotelian thought?

1."i set a high price on eloquence, and i was in love with poetry; i rejoiced in mathematics, but knew nothing of its true use."

2."thus, because our senses sometimes deceive us, i would suppose that nothing is such as they make us to imagine it . . "

3."[c]onsidering that all the thoughts we have when awake can come to us also when we sleep without any of them being true, i resolved to feign that everything which had ever entered my mind was no more truth than the illusion of my dreams . . "

4."the time remaining to me i have resolved to employ in trying to acquire some knowledge of nature, such that we may be able to draw from it more certain rules for medicine than those which we possess."
