Ok

I read one of Parfit's essay on personal identity. And then I thought of what psychology and sociology might say on personal identity. And then I thought that while they may have interesting insights to offer, nothing can be more exciting, intellectually, than philosophy.

I am not one who seeks to show that philosophy has practical applications. I don't think there's a strong need to, unless when making a shrewd move to preserve or extend the vitality of the discipline. There is something about the abstractness of philosophy that makes it attractive to me. Very few people care if the A-series or B-series conception of time is correct, or neither. I don't think it's a matter of grave importance. Nonetheless, I find it pleasurable reading articles on them, and it's a pleasure no other discipline can give.
