If the universe is completely deterministic or even just completely mechanistic, we are all machines without true control of ourselves. If, through science, we can determine that this is in fact the case, it would affect the behavior of at least some humans to behave erratically or to completely follow their self-interests. In my mind, a deterministic universe that makes intelligent creatures who can figure out that they have no free will and therefore change their behavior - again, not freely - is perverse.

1. Is the universe merely God's wind-up toy? Did he invent time just so he could play? Could a pre-destined outcome bring him any joy? Or does he just like watching night turn to day? 2. Or does God allow random things to happen Like a gambler at a casino craps game Never knowing if the next throw will be 12, 5, or 7 But all the time the rules remain the same? Chorus: I want to live in a world where I'm free To choose what I think, do, and say! If I ever find out that I'm just a machine I'll start acting in a most disturbing way! 3. Maybe the universe is just the product Not of God but some unthinking force field I'm still a machine and the universe a wound-up clock But I couldn't even prove that it's real! [Chorus] Bridge: If we find out that free will's just an illusion Won't we become completely disillusioned And engage in the most self-serving actions? Won't that be our natural reaction? [End with chorus]
