Thinking each each paragraph as a mini-essay is an excellent way to approach this: The first line (or topic sentence) is the introduction, and it should describe what you will explain in that paragraph and how it links to the one before it; the center of your paragraph is comparable to the major body of the essay, in which you repeat your stance. Finally, the last line (or conclusion) restates your main point and finishes off your argument. To start with, you need to decide what aspect of philosophy you want to explore. It can be something as simple as a particular philosopher, such as Descartes or Kant, or it can be a more general topic, such as consciousness or freedom. Once you have decided on your topic, it's time to search for information relevant to it. Start by reading as much as possible about this issue within the context of philosophy. This will help you understand what others have said about it and give you ideas for your own contribution to the debate. Remember that an essay isn't just about giving your opinion - even if you feel strongly about something, there must still be a reason for explaining your view instead of someone else's. Once you know what you are going to say, it's time to start writing. First, draw up a list of everything you think could be important regarding your topic. Next, choose one topic from this list and discuss it in more detail.
