Does doing an undergraduate math major make an applicant for philosophy phd programs more competitive? I'm majoring in philosophy at my undergraduate university but I've also taken a fair number of math classes. I've generally found that taking math classes is very time consuming and dramatically limits the amount of time I can spend working on philosophy classes. On the other hand, I feel like I learn a lot in the math classes that sometimes influences how I think about philosophy. I'm a junior and I would need about 4 more math classes for a math major (I have three semesters left before I graduate). For purposes of admissions to philosophy phd programs, should I continue to take math classes and get a math major (in addition to philosophy), or should I just focus on philosophy?

ADDED: I understand that math will be helpful to me in studying philosophy. I am specifically interested in whether it is worth studying in the remainder of my undergraduate career given the opportunity cost for my ability to focus on philosophy.
Recommend getting the math major if you can. (I have double bachelor's in philosophy &amp; math myself, although my graduate school and professional work was in math.) 

The undergraduate study is the best time to expand yourself into as many fields as you'd care to take. Generally, graduate school is the place that demands exclusive focus on one narrow area. So the opportunity you have now will not be available later on; and the degree will document permanently that you can achieve in any field you need to work in. 

Plus, there's the possibility that later in life you may wish to adjust or switch fields. Having the math degree will allow you to immediately step into programs in any science-related area you wish. 

Standing astride two separate fields like an academic Colossus gives you a perspective and options that few others can match, and now is the very best time to establish that.
