A commentary from Scientific American argues life does not exist:
“Why is defining life so frustratingly difficult? Why have scientists and philosophers failed for centuries to find a specific physical property or set of properties that clearly separates the living from the inanimate? Because such a property does not exist. Life is a concept that we invented. On the most fundamental level, all matter that exists is an arrangement of atoms and their constituent particles. These arrangements fall onto an immense spectrum of complexity, from a single hydrogen atom to something as intricate as a brain. In trying to define life, we have drawn a line at an arbitrary level of complexity and declared that everything above that border is alive and everything below it is not. In truth, this division does not exist outside the mind. There is no threshold at which a collection of atoms suddenly becomes alive, no categorical distinction between the living and inanimate, no Frankensteinian spark. We have failed to define life because there was never anything to define in the first place.”
When I posted this on my Facebook page a few Christian friends objected. I am quite non-religious myself, but I feel there is still a strong philosophical argument that can be made for accepting the paragraph above and maintaining one’s faith in God:
I find this explanation wholly consistent with the existence of God. If both God and people exist he evidently made us out of something. Simply because he chose the same something to make both humans and, say, chairs does not imply there is not a hidden spiritual division between the two groups of atoms. Presumably God did not design a world where faith can only be accessed through a sophisticated understanding of modern science; otherwise He has condemned the unscientific mind without due consideration. Rather, faith in God’s existence should be apparent simply from the beauty of our visible world, the spiritual ties we feel toward one another, and the subtle yet distinct direction from God in our lives (which is especially evident after introduction to the teachings of Jesus Christ). That is, faith must be immune to the vicissitudes of scientific thought. Faith must be flexible enough to accept scientific discoveries in the physical and natural sciences, but rigid enough to maintain value in its own right. Some might say that science is the champion of imagination, but that faith is the ruler of the heart.
