well then, again it can't hurt if you have a good grade in it. It may look strange if you have a C or low B in a course that i just reading and discussion. But that being said it probably will not help you that much, what does it show? That you can read well and think critically and hold discussion about readings, that is certainly a good skill but it is one that may be pre-assumed for most people. Now if it was also tied into research, then that would be good. If it was a reading and discussion class perhaps say you take the whole semester to read and discuss one topic, like a particular version of string theory, and then it culminates with a long paper or presentation given. That former choice may hold more weight because it shows you can do some independent learning and research and make something substantial out of it.
