the aikido I know has a very deep philosophical points such as: non violence, non ego/self, etc. but it's still an effective martial arts for self defense. I know we're supposed to train both but in dojo, which part should we be more focused on? philosophical or practical side?
depends on the kind of person you are. if you are more philosophical and spiritual then you are more than likely will focus on those things. if you are a practical person, then that would be your focus. but it doesn't have to be either or. can be both. just because you are practical doesn't mean you are not philosophical about it, and vice versa. just because you are wearing a skirt, doesn't meant you are not a cross dresser.
