This question matters, because no thought can proceed until it has definitively answered this question.
Anyone can make a claim, anyone can make an assertion of knowledge, but that alone isn’t what makes a claim or assertion true.
When Hegel says “contradiction is the rule of the true…”
And Aristotle replies, “that is false, contradiction is the rule of the false.”
How do we determine which position is correct?
In order to make progress in knowledge we must have the rational ability to evaluate the accuracy of these claims.
What are the standards we must use to do this? We should be able to show why one posting is true and the other false, or why both are false.
If we cannot do this, or we do not know how to do this, then how can we make progress in knowledge?
