Is there an African philosophy

Every human person by nature is rational, by the the participation in that essence rationality, any person is capable to reason. The fact is that there can be no philosophy without a rational being in act, here using the principle of causality, I maintain that reason is the causality) of philosophizing. Now for the fact is that every being act according to its nature, it is impossible to refuse or deny of a rational being the act of philosophizing. For by the virtue of participation in the concept rationality the causality of philosophy, the objection of a philosophy to an African native should be revised. like Aristotle affirms with Aquinas man is rational being by nature, therefore by that participation in the power of reason an African has his own philosophy. For every philosophy has a context, moment of influence, materiel and object of philosophizing. This is the reason why an African philosophy has its own concern of matter of philosophizing: leading to what is particularly African philosophy.
