Erwin Chargaff - Later Life

Later Life

Beginning in the 1950s, Chargaff became increasingly outspoken about the failure of the field of molecular biology, claiming that molecular biology was "running riot and doing things that can never be justified." He believed that human knowledge will always be limited in relation to the complexity of the natural world, and that it is simply dangerous when humans believe that the world is a machine, even assuming that humans can have full knowledge of its workings. He also believed that in a world that functions as a complex system of interdependency and interconnectedness, genetic engineering of life will inevitably have unforeseen consequences. Chargaff warned that “the technology of genetic engineering poses a greater threat to the world than the advent of nuclear technology. An irreversible attack on the biosphere is something so unheard of, so unthinkable to previous generations, that I only wish that mine had not been guilty of it.”

After Francis Crick, James Watson and Maurice Wilkins received the 1962 Nobel Prize for their work on discovering the double helix of DNA, Chargaff withdrew from his lab and wrote to scientists all over the world about his exclusion.

Famous quotes containing the word life:

    It is a conquest when we can lift ourselves above the annoyances of circumstances over which we have no control; but it is a greater victory when we can make those circumstances our helpers,—when we can appreciate the good there is in them. It has often seemed to me as if Life stood beside me, looking me in the face, and saying, “Child, you must learn to like me in the form in which you see me, before I can offer myself to you in any other aspect.”
    Lucy Larcom (1824–1893)

    Greater love hath no man than this, that a man lay down his life for his friends.
    Bible: New Testament Jesus, in John, 15:13.

    In Ulysses, James Joyce wrote, “Greater love than this ... no man hath that a man lay down his wife for his friend.”
