The thesis

There are two kinds of undergraduate philosophy papers: those that have theses and those that do not. By a thesis I mean a clearly stated and defended claim that constitutes the topic of the paper. The thesis of a paper should

The introduction

As noted already, you will probably want to put your thesis in your introduction. At any rate, you want to say something to orient the reader to your topic. In writing your introduction, avoid

Argumentative strategies

Students sometimes have a difficult time in arguing for their views. This is natural. The result, however, is that your paper makes claims that are never defended. You want to avoid this. So you must find a way not just to give me your own opinion (which is an absolute requirement in the paper), but also to defend that opinion. In other words, it is not enough simply to say: "it is my view that the law must always be obeyed." I want to see you say something like that. But the next thing I want to see you say is: "I believe this because...." And this is the hard part -- to argue for the things you believe.

The way philosophical arguments almost always work is by beginning with assumptions or premises that the reader is likely to accept. So if you are defending the above view about obeying the law, you might start by making some less controversial assertions. Try saying, for instance, that you think promises should always be kept. (But be ready to return to this claim; couldn't someone think of an exceptional case where a promise shouldn't be kept?) Then compare keeping a promise to obeying the law. (There is an analogy here, isn't there? Socrates, at any rate, seemed to think so.) Then conclude that the law should always be obeyed. Maybe you don't think this is a very good argument. That just shows how hard it is to make good arguments. But what's crucial is that you try to argue for the things you state.
