Who was born first, you or the world? As long as you give first place to the world, you are bound by it; once you realize, beyond all trace of doubt, that the world is in you and not you in the world, you are out of it. Of course your body remains in the world and of the world, but you are not deluded by it.
Human beings are infinitely fallible, completely unreliable. Science is not. Science is absolute. Under strict principles, if you do A and B, then C will occur. This rarely happens if you inject the inefficiences of humanity into the process.
