... Another writer again agreed with all my generalities, but said that as an
inveterate skeptic I have closed my mind to the truth. Most notably I have
ignored the evidence for an Earth that is six thousand years old. Well, I
haven't ignored it; I considered the purported evidence and *then* rejected
it. There is a difference, and this is a difference, we might say, between
prejudice and postjudice. Prejudice is making a judgment before you have
looked at the facts. Postjudice is making a judgment afterwards. Prejudice
is terrible, in the sense that you commit injustices and you make serious
mistakes. Postjudice is not terrible. You can't be perfect of course; you
may make mistakes also. But it is permissible to make a judgment after you
have examined the evidence. In some circles it is even encouraged.
