Quite different are empirical truths. All the findings of science are empirical: they are based on evidence, and might be wrong or incomplete. Also, we can be wrong about what we think we see or experience. Of course, we rely on science and our senses in practical life. That does not alter the fact that absolute truth is only to be found inside a well-defined logical system. That kind of truth may, or may not, correspond to the real world.
