10. The Argument from Consciousness

When we consider the universe, we are left in awe of its order and intelligibility.  We experience something only intelligence can grasp.  And yet, the universe itself is not intellectually aware.  These facts lead us to a variation on the argument for design. 

1. "We experience the universe as intelligible.  This intelligibility means that the universe is graspable by intelligence.
2. Either this intelligible universe and the finite mind so well suited to grasp it are the products of intelligence or both intelligibility and intelligence are the products of blind chance.
3. Not blind chance.
4. Therefore this intelligible universe and the finite mind so well suited to grasp it are the products of intelligence"  (Handbook of Catholic Apologetics, pg. 71).

Let's focus on number 3.  How do we know it isn't blind chance? 

"Blind chance" is the way nature operates without any rational plan or guiding purpose- in other words, naturalism. 

"For by Naturalism we mean the doctrine that only Nature- the whole interlocked system-exists.  And if that were true, every thing and event would, if we knew enough, be explicable without remainder as a necessary product of the system" (Miracles, C.S. Lewis, pg. 18). 

So if Lewis' argument is true, than step 3 remains.  Blind chance cannot be the source of our intelligence.
