Be mindful of the language you use. Simple, short sentences will help make your essay clearer. Also, it is important to structure the essay effectively. Each argument should be developed in a single paragraph and counter-arguments should be provided to balance your claim. By providing a clear answer to your question in the introduction and the structure enabling you to reach that answer, you are helping the reader understand your train of thought. Relevant examples and sound, valid arguments displaying balanced and critical thinking are essential in a well written philosophy essay.
