Truth never fears investigation What is truth? Like earth moving around sun, water flowing downward, summer coming after spring, truth is something that inevitably happens or exists in the world that no one would deny. What is investigation? It is experiment, survey or observation that conducts to prove the accuracy of something. Do truth and investigation born to be enemies? Faced with comprehensive and rigid investigation, what the fate of truth will be？ Definitely, truth will never fear investigation! Truth is destined to be unchanged no matter what the world will be. Will sun rise from west, earth turn to be square, people live a healthy life without food? Of course not! If all these happened, earth would in disaster! If truth changes, what else we could believe in the world? All our minds will in a mass! In my opinion, Investigation does not deny truth, however it proves truth to the people who are suspicious of it, being a powerful evidence of truth. Then investigation is a tool for truth to convince people believing it. We always say action speak louder than words. Words are based on investigation; action is what we assume to be true. Investigationdoes not hold water in front of truth if it does not comply with truth. Investigation tends to be so vulnerable compared to truth.
