From the Harvard guide (https://hwpi.harvard.edu/files/hwp/files/bg_writing_philosophy.pdf):
Begin by formulating a precise thesis - state what your paper wants to achieve clearly and concisely in its introduction.
Define technical or ambiguous terms used in your thesis - write so your work can be understood by a student who has little or no philosophy experience.
(If necessary) motivate your thesis - explain why the reader should care about it; useful in longer assignments or when it’s unclear why the reader should care/
(If necessary) explain the argument you will be critiquing - if you are asked to critique an argument, you will need to explain the argument before you can critique it.
Make an argument to support your thesis - the main focus of your paper; do not skip steps or rest on any premises/principles the reader may be unwilling to accept.
Avoid a “shotgun” approach of multiple weak arguments - stick to one or a few strong, well-defined arguments.
Anticipate possible objections to your thesis - consider how these objections might challenge your position and prepare counterarguments that reinforce your main claim.
From the Harvard guide:
Scientific/empirical evidence: Explain exactly why the evidence relates to your philosophical question, and accurately report the evidence.
Argue from fallacies: Show the failures of the argument by identifying any inconsistencies that weaken opposing claims.
A reductio: Fallacy that results when two or more independently strong arguments that, when combined, introduce an implausible separate claim.
Question-begging argument: An argument that uses a premise one would reasonably doubt if a person didn’t accept the conclusion the argument is trying to establish.
Using examples: hypotheticals or real-world examples that demonstrate how the argument would work out.
Avoid quotes - quote sparingly, and when you do, follow up the quote by paraphrasing what the author means.
Use 1st person pronouns & possessive pronouns freely
Say exactly what you mean
Be careful with specialized language.
This includes phrases like deduction, begs the question, valid, invalid, vague - these often have specific meanings.
