Understanding Media: The Extensions of Man

by Marshall McLuhan

In accepting an honorary degree from the University of Notre Dame a few years ago, General David Sarnoff made this statement: “We are too prone to make technological instruments the scapegoats for the sins of those who wield them. The products of modern science are not in themselves good or bad; it is the way they are used that determines their value.” That is the voice of the current somnambulism. Suppose we were to say, “Apple pie is in itself neither good nor bad; it is the way it is used that determines its value.” Or, “The smallpox virus is in itself neither good nor bad; it is the way it is used that determines its value.” Again, “Firearms are in themselves neither good nor bad; it is the way they are used that determines their value.” That is, if the slugs reach the right people firearms are good. If the TV tube fires the right ammunition at the right people it is good. I am not being perverse. There is simply nothing in the Sarnoff statement that will bear scrutiny, for it ignores the nature of the medium, of any and all media, in the true Narcissus style of one hypnotized by the amputation and extension of his own being in a new technical form.
