The criterion for judging everything in the world is the truth, facts as they are. If you can see the truth (facts) properly, you can achieve what you want or solve problems. By the way, it is not easy to see the truth of what exists, facts as they are. For that reason, people invent tools such as thoughts, isms, ideologies, faith, theory, etc. to see the truth. However, they do not know that such actions are distorting the truth beyond the question of whether they can see the truth (facts).
