Moved to Personal Statement Advice
You can mention history by name but for the philosophy side of it, instead of specifically saying philosophy, maybe talk about how history is open for interpretation etc.? Not sure what else to suggest, but I hope this helps somewhat. I'm currently having the same issue with applying to different courses that are basically the same in all but name.
It's unwise to choose to apply for different courses - why are you not applying for single honours history at York?
I know you can do history and philosophy at other universities but just not at the ones I've selected, and I'm a bit fussy when it comes to the history part. I would like to do the joint degree as personal preference. If I went to the other universities then I would do a philosophy module
You will struggle to write a PS that will adequately cover both types of courses tho
You've had lots of advice already, but I wanted to add that admissions folk are very used to statements that have to be tailored to more than one course and won't penalise you for it. If you're worried you should contact the admissions tutors at the departments you're interested in: they are always happy to answer questions in that way.
