MA Philosophy or Master of Arts in Philosophy is a 2-year postgraduate course that offers knowledge related to Schools of Classical as well as Modern philosophy. 

The minimum eligibility required to pursue this course is a bachelor’s degree from a recognized institute with philosophy or any related subject as the major subject. 

Yes, you can pursue an MA in Philosophy even if your Bachelor is unrelated to the field. However, you might have to portray the fact that you have the critical thinking skills to benefit from an MA in Philosophy. It’s even better if your Bachelor is in the humanities and social sciences rather than the hard sciences. So it would be a bit challenging if you had no background in philosophy, but having a BA in philosophy isn’t necessary.

Usually, an MA in Philosophy requires a writing sample that is at par with the ones submitted by candidates who have done a BA in Philosophy.
