Claims, reasons and assumpitons

Claims, reasons and assumptions are very important, albeit similar, aspects of a good paper.  All three of these aspects must work together to effectively convey your point to your readers. In my opinion the claim is the most important of these.  The reason being it states what your view is.  Without a view on a topic, you have nothing to argue, therefore you cannot write an opinion editorial.  Stating your view powerfully is very important in writing a good paper, you have to be clear with your statement.  Reasons are to be the main body of an essay.  Your reasons must support your claim, make sense to the listener, and be clear and to the point.  Reasons are the way of persuading the reader.  If you don't have good reasons that make sense, your paper will be for naught.  The assumpition part of the paper is still kind of confusing to me.
