Hmm...having touched a large number of subjects, philosophy has come before my path a few times. However, upon further research, I discovered that it is too much of a personal and subjective matter to actually discuss with other people - even more so, considering the fact that few people have a stable view of the world, since everything changes (one may argue the timelessness of certain ideas, but I doubt it can be proven within a lifetime).
Psychology, on the other hand, promotes teamplay
I consider the knowledge of psychology a very useful tool in communication; it is made easier and much more fun, particularly when you start to seek out the reasons behind all kinds of behaviour and responses.
