In fact, it's not that valuable.

Inevitable sacrifice.

The idea current human beings consider as the best is actually just a piece of source for the later human beings. Although it doesn't mean that the every right thing in the past is not totally wrong, if it is considered as not suitable for present, then it is just wrong.

Absolute truth. It is a non-sense but it is worthy. Because the belief in it can only give people an excuse and so that people can believe and say positively 'We are closing to the truth and the justice. We are developing'.

Truth we have is not the truth. It's just a belief that we have truth.

That is, it's merely a poor justification of this present time.
