(Biologist Anthony R. Cashmore of the University of Pennsylvania, writing in an address to the National Academy of Sciences and quoted in this post from BioEdge.)
Dr. Cashmore, because he can't find "free will" in a petri dish or capture the soul in a test tube makes the mulish determination that they just don't exist. Very sad...and quite irrational. For though, Dr. Cashmore argues against the mind, against spirituality, and against freedom, he does so only on an irrelevant level. He cannot (and doesn't want to) actually live out those beliefs. He loves, he yearns, he hopes -- he deliberates over what shirt to wear, what to have for breakfast, what toys to give the children he loves.
No, Dr. Cashmore simply cannot live like one of the plants in his science lab. Because for all of his protestations to the contrary, he is a human being. He is created in the image and likeness of God. He has an eternal soul, one that is fully free and capable of responding to the sublime invitation of the gospel -- and one, therefore, that is free and fully responsible for his rejection of that divine invitation.
Dr. Cashmore is a pitiable egotist and a too-common example of the damaging absurdities to which many modern scientists have dedicated themselves. Say a prayer for him -- you are completely free to do so.
