Truth existed before the world began and will still be persisting until long after the world ends, so therefore 'source of truth' really has no bearing on anything. What is important is the discovery of truth and its application. That is, to what purpose is the truth put, to what goals it is used for, the method in which the truth is applied, to what benefit the truth is used, that is, who benefits by its use or its non-use or its being hidden or exposed. Such things as truth, facts, knowledge and discoveries, and techniques, are tools, and they in themselves don't have the ability to create or cause any action, effect or result. It is what people do with them that is important. It's the Being behind the tool. A scalpel can cut your throat or it can repair a body. A hammer can bash somebody's brains out or build a house. Therefore, what's more important is the individual's intention and action with that tool, not the tool itself.
