I already did the essay but I got a B in it. If I fix the essay i have a chance to get an A. On the attached file (essay), there are some notes on what to do and what to fix. Please fix all the mistakes and try to be consistent as much as possible. The required book to write the essay is David Hume, Enquiry Concerning Human Understanding you can use this book as the main source for the editing, which is also attahced in a file, (The due date is tomorrow evening). The Essay was written based on this question: 
Hume says that we should ground knowledge on what he calls “impressions” rather than on the “clear and distinct” rational principles that Descartes views as foundational.  What does Hume mean by “impressions” and why does he start there?  Is he right?  Defend or criticize Hume’s empiricist starting point.
