What does learning history teach you about yourself?

it helps to understand your own shadows, to know that even the nicest of humans can, indeed, cause the most harm. Even those who you deem great, and perhaps even admire, may have done awful, horrific even, awful things.

History teaches us to learn from our mistakes and past experiences. it allows us to avoid making the same mistakes over and over again. ... Why to study history; to know yourself, to know your world, to know others. I think history is a very important lesson.
