Philosophy, one may state, is a field where one makes descriptive statements about the world - whether it's in ethics, metaphysics, logic, or any other philosophical study.
For example "the world is made out of physical entities" is a descriptive statement, and "all bachelor's are not married" is another. While on the contrary, scientific statements, one may state, are those of predictive power. Like, for example, "a ball that rolls down the hill would keep on rolling until something stops it", and "if a man that changes social groups, his social status would probably change, more often than a man that stays within his original social group".
Is this distinction between philosophical statements and scientific statements correct? Do philosophical enquiries not have predictive power?
Just to be clear, this question isn't about what differentiate philosophy from science; I merely use science as a contrast to something that doesn't involve prediction (as most would say that prediction is science's goal).
