Scientists are not to be taken lightly. And, in any case, I should be very surprised if the story I have to tell is anywhere near the whole truth. We are all, as Huxley says someplace, Great Abbreviators, meaning that none of us has the wit to know the whole truth, the time to tell it if we believed we did, or an audience so gullible as to accept it. But you will find an argument here that presumes a clearer grasp of the matter than many that have come before. Its value, such as it is, resides in the directness of its perspective, which has its origins in observations made 2,300 years ago by Plato. It is an argument that fixes its attention on the forms of human conversation, and postulates that how we are obliged to conduct such conversations will have the strongest possible influence on what ideas we can conveniently express. And what ideas are convenient to express inevitably become the important content of a culture.
I use the word “conversation” metaphorically to refer not only to speech but to all techniques and technologies that permit people of a particular culture to exchange messages. In this sense, all culture is a conversation or, more precisely, a corporation of conversations, conducted in a variety of symbolic modes. Our attention here is on how forms of public discourse regulate and even dictate what kind of content can issue from such forms.
To take a simple example of what this means, consider the primitive technology of smoke signals. While I do not know exactly what content was once carried in the smoke signals of American Indians, I can safely guess that it did not include philosophical argument. Puffs of smoke are insufficiently complex to express ideas on the nature of existence, and even if they were not, a Cherokee philosopher would run short of either wood or blankets long before he reached his second axiom. You cannot use smoke to do philosophy. Its form excludes the content.
To take an example closer to home: As I suggested earlier, it is implausible to imagine that anyone like our twenty-seventh President, the multi-chinned, three-hundred-pound William Howard Taft, could be put forward as a presidential candidate in today’s world. The shape of a man’s body is largely irrelevant to the shape of his ideas when he is addressing a public in writing or on the radio or, for that matter, in smoke signals. But it is quite relevant on television. The grossness of a three-hundred-pound image, even a talking one, would easily overwhelm any logical or spiritual subtleties conveyed by speech. For on television, discourse is conducted largely through visual imagery, which is to say that television gives us a conversation in images, not words. The emergence of the image-manager in the political arena and the concomitant decline of the speech writer attest to the fact that television demands a different kind of content from other media. You cannot do political philosophy on television. Its form works against the content.
To give still another example, one of more complexity: The information, the content, or, if you will, the “stuff” that makes up what is called “the news of the day” did not exist—could not exist—in a world that lacked the media to give it expression. I do not mean that things like fires, wars, murders and love affairs did not, ever and always, happen in places all over the world. I mean that lacking a technology to advertise them, people could not attend to them, could not include them in their daily business. Such information simply could not exist as part of the content of culture. This idea—that there is a content called “the news of the day”—was entirely created by the telegraph (and since amplified by newer media), which made it possible to move decontextualized information over vast spaces at incredible speed. The news of the day is a figment of our technological imagination. It is, quite precisely, a media event. We attend to fragments of events from all over
