Sorry but I really don't think it's a good idea to apply for so many different courses, with just one personal statement. You're going to have to include elements of history, religion, politics, classics and science, alongside the philosophy, to pull this off.
If you're set on those particular choices, I'd suggest emailing the universities, explaining your situation a little bit and asking if you can send them a separate personal statement, which you can then specifically tailor to that course.
