Replying to I need a wise man

So,

I have a philosophy paper to write and I am stuck on the topic. It can really say anything because my professor is a crazy old drunk so if you have a second, try and think of how I could refute this argument. I'm having some trouble because I agree with it. He also never taught it.


And it goes,

Aristotle says that science is the thing that gives 100% true results because things can be counted perfectly.

He says that because one thing is correct, everything based on it will be true. And everything that is based of those will be correct.

[End of the assignment paper] "We don't believe science yields certain results. Give a critical analysis of Aristotle's position on the certainty of science"
