The subject in Western philosophy

Should there be a subject? 

Is there a difference between observing an external object and the internal one called the subject? 

Is it here that Western philosophy fails?

Another person’s object can be a subject, and vice versa. By label of subject have we not created a subject-centric of the world when really there is no central view?

I can sympathise with OOO for this reason. But at the same time with sense as the only access to the world, we have no choice but to have a central view.
