What does this quote about noncontradiction mean?

Question

whenever you think you are facing a contradiction, check one of your premises and you will find that one of them is wrong. could someone please explain this

Answer 1

This is an assumption based on Aristotelian three value logic and does not hold in all cases.

Answer 2

A contradiction cannot exist. An atom is itself, and so is the universe; neither can contradict its own identity; nor can a part contradict the whole. No concept man forms is valid unless he integrates it without contradiction into the total sum of his knowledge. To arrive at a contradiction is to confess an error in one’s thinking; to maintain a contradiction is to abdicate one’s mind and to evict oneself from the realm of reality.
