Is unbiased history writing possible?
Technically, no there is no way in which to write an unbiased history. The problem with bias in history is that every human in this world is biased, whether they are intentionally or not, and if you give two people the same account from which to write a history you will always get a different account. People will always project their own interpretations onto history, whether that be through intentional or unintentional practices. It is true that modern history is as unbiased as it as ever been, but this does not mean that it is totally objective, only as objective as it can be.
