It’s always amazing to me how little the objections to Christianity have changed, and how enduring the answers to those objections are – from the immensely wise mind of G.K. Chesterton:
Dear Mr. Chesterton,
A famous anthropologist has recently demonstrated quite conclusively that the physiological formation of the ape and the human, including their brains, are almost exactly alike…Don’t you think he proved something rather devastating to your philosophy?
Signed, Dr. K.
Dear Dr. K.,
If he was trying to prove that man has a merely material origin like the ape, he was proving exactly the opposite. If there are two motorcars, which a minute examination proves to be exactly alike in every mechanical detail, then we shall be rather more and not less surprised if one of them suddenly soars into the air like an aeroplane, while the other can only trundle along the road like a cart. The only way in which we can possibly explain it is to suppose that, at some time and in some way, some other more mysterious force came into play. But the more we prove that every cog and rivet in the two machines is identical, the more we are driven to the mystical explanation when their action is different. And the difference between a man and an ape does not need discussion, it does not allow of denial or even doubt. Man has stepped into a totally different world of imagination and invention; like a man turning into a god. If this startling and stupendous difference can co-exist with exactly the same material origins, the only possible deduction is that it does not come from the material origins. In other words, the only possible deduction is that by some special spiritual act, as in the ancient record, man became a living soul.
Your friend, G.K. Chesterton
