The novel is one of the best ways to put across ideas. However it requires a lot of input and you yourself will have to be pretty good at creative writing if you want to perform this type of writing. One example would be Ayn Rand or Dostoyevsky’s ‘The brothers Karamazov’ or ‘Crime and Punishment’.
After writing a basic philosophical statement add some more “big” words to replace more common ones (i. e. good, bad, nice, etc. )and transitions to get your basic idea across. After doing so, re-read and make sure you make sense; afterwords read it to a friend or relative and see how they react; after correcting what mistakes they are able to find in your grammar or logic you are practically done. Feel free to and an introduction and/or conclusion or have a friend/relative do that for you. Read Thomas Paine’s Common Sense, or some Immanuel Kant to get a good format as well.
