# Theory Is Sense Theory = Sense. This is not an inclusion. This is an equal. What people call "sense" specifically is just an innate theory. As I once wrote, why you can see a clear object while you have two ey es is because there's already an optical theory in your mind. Of c ourse there are biological differences, but those just mean that y our body has less / more theories. Conversely, a physicist can SEE a specific particle in an image fr om a particle detector, but you (probably) can't. That's because y ou don't know the theory. Similarily, you can understand a convers ation if you know the language, but otherwise it is just a sequenc e of sounds for you.
