"We found what we could at that time - the truth. If somebody else can find something else which we didn't find, that, of course, is a duty on their part, as is the truth. It will be the truth"

John Sherman Cooper's quote talks to the suggestion that fact is ever-evolving which it is our obligation to seek it out. He recommends that what we have actually found to be true at one moment might not coincide truth that someone else finds in the future. He urges us to remain to look for the truth, as it is our obligation to do so. He also implies that the reality is not static, yet rather something that can be discovered and also uncovered. This quote urges us to be open-minded and also to remain to look for the reality, even if it is different from what we have formerly found. It is a tip that reality is not something that can be taken for approved, but something that needs to be proactively sought.
