No need. You don't need to have excellent mathematical ability to learn philosophy. The focus of philosophical research is mainly on thinking, analyzing and explaining abstract concepts and problems such as human thinking, values, morality and existence, rather than mathematical operation or quantitative analysis. Philosophy is a humanities subject, and its research object is human thinking, knowledge, morality, ethics and other fields. The core of philosophy lies in logical thinking, critical thinking and analytical ability, not mathematical operation ability. Philosophy majors pay more attention to students' critical thinking ability.
