The truth exists, but often we cannot know it, ie incomplete information, biases, etc. Or sometimes you may be predicting the future where it absolutely doesn't exist yet - you plan a new policy to improve something, but you can never find "the truth" in advance, eg whether it will work or not. But if we challenge our opinions, we can make better decisions. If we challenge and they hold, we are more confident in them. If we challenge and they don't hold, maybe there's a better idea to explore. In short, what I believe is: you can aim for the truth, and you will be better for it, but you will never reach it.
