Let me just quote ysg_62 here,

But yeah, the study of history and culture is so essential that I cannot think of where to begin. For a good ‘education’, it is surely essential to know history and culture of not just our own, but also of other peoples in the world.

This knowledge is basically telling us what the humans have been doing here for centuries and more. And how different mindset leads to different choices and different consequences. And what happens when one confronts the other. And yet, even with so many differences, at times we feel oneness. This study is very essential. And skipping this, there can be no ‘education’.
