Historians know not only that context always matters, but also that contexts change.
There are many different points in history where certain events happened, and the context is always different, so it is very important to understand the context in situations. It helps us make sense of the past and avoids judging decisions made hundreds of years ago according to modern standards. It helps us to not oversimplify things.
Historical empathy helps us to understand how people perceive and shape context, process, and change.
This humanizes everybody in human history because it highlights that people in ancient times weren't just living, they were also perceiving their world and using that to make the decisions they made, just as we do. When we put ourselves in someone else's shoes, we can better see why they made the decisions they made whether we agree with the decision or not. It is something that I believe can help with biases.
Everything has a history.
A line as simple as it gets yet it's quite complex if you look at it deeper. I agree with this statement because of that. Every single thing in life has a history whether it be short term or long term. Everything exists because of countless different decisions and discoveries over time. This will always be true.
