Philosophy is a branch which is connected to everything that exists in the world, whether it’s real or unreal, imaginary or unimaginary. But it’s also more than that because a person has a vast scope to know about and think of things around him/her. And as an individual too, we are naïve about our own inner self too, most of the times.
