A thesis statement usually appears at the end of the introductory paragraph of a paper , and it offers a concise summary of the main point or claim of the essay , research paper , etc. A thesis statement is usually one sentence that appears at the beginning, though it may occur more than once.  The thesis statement is developed, supported, and explained in the course of the paper by means of examples and evidence . Thesis statements help organize and develop the system of proper writing. They are essential components of scholarly research papers.
If I went to a doctor and said “Tell me how to diagnose a patient,” or I went to a judge and said “Tell me how to interpret the law,” or I went to an artist and said “Tell me how to be creative,” do you think they would be able give me a few sentences that completely answer my question and prepare me for professional work as a doctor, judge, or artist? If they had spent years as students learning their subject matter, and additional years teaching or writing a textbook on their specialty, they might be very good in their professions but I’d bet they’d all find it tough to answer such a question in any meaningful way.
These words tell the reader next to nothing if you do not carefully explain what you mean by them. Never assume that the meaning of a sentence is obvious. Check to see if you need to define your terms (”socialism," "conventional," "commercialism," "society"), and then decide on the most appropriate place to do so. Do not assume, for example, that you have the same understanding of what “society” means as your reader. To avoid misunderstandings, be as specific as possible.
