UC Berkeley Professor George Lakoff discusses concepts from his 2008 book, The Political Mind: Why You Can't Understand 21st-Century American Politics with an 18th-Century Brain.
"The Reed-Kellogg diagram is a tool of the classroom and of the textbooks that codify the rules for its production. But grammar textbooks share a problem similar to the one Thomas Kuhn noted for science textbooks: they tend to efface the history of their subject. Indeed, grammar textbooks are far more ahistorical that science textbooks. The average science textbook will contain some history, however Whiggish. There will be at least a cursory mention of the scientists who formulated the theories under discussion, some suggestion that scientific knowledge is subject to change and accretion. Grammar, however, comes to students as an abstract whole. The sources from which the textbook authors derived their accounts normally go unacknowledged. There is no sense of grammar as a theory—or, more precisely, a constellation of competing theories—with its own intellectual history."

"Facebook, for example, encourages phatic communication through sociable add-ons like 'vampire bites', 'zombies', 'hot potatoes' and automating messages encouraging participation between friends in quizzes, film taste reviews and the like. Furthermore, Facebook's new 'beacon' technology creates an environment where one's online purchases and interests get relayed to one's network of friends through automated communication. Twitter encourages phatic communication through the imposed limits of the medium itself. The 160 character limit for messages creates brevity in communication. The lack of a private messaging facility, promotes generic 'announcements' over dialogue or targeted conversation. "

 For example, a typical automated message such as ''Mr X' has challenged you to a movie quiz' suggests a personal invitation to compete. However, it is usually the case that if 'Mr X' has participated in a movie quiz, you will, by default, be automatically 'challenged' to the quiz, by virtue of being friends with 'Mr X'.

"In order to separate from the whole of speech the part that belongs to language, we must examine the individual act from which the speaking-circuit can be reconstructed. The act requires the presence of at least two persons; that is the minimum number necessary to complete the circuit. Suppose that two people, A and B, are conversing with each other [see figure 1 below].
Suppose that the opening of the circuit is in A's brain, where mental facts (concepts) are associated with representations of the linguistic sounds (sound-images) that are used for their expression. A given concept unlocks a corresponding sound-image in the brain; this purely psychological phenomenon is followed in turn by a physiological process: the brain transmits an impulse corresponding to the image to the organs used in producing sounds. Then the sound waves travel from the mouth of A to the ear of B: a purely physical process. Next, the circuit continues in B, but the order is reversed: from the ear to the brain, the physiological transmission of the sound-image; in the brain, the psychological association of the image with the corresponding concept. If B then speaks, the new act will follow-from his brain to A's-exactly the same course as the first act and pass through the same successive phases, which I shall diagram as follows [see figure 2 below].
The preceding analysis does not purport to be complete. We might also single out the pure acoustical sensation, the identification of that sensation with the latent sound-image, the muscular image of phonation, etc. I have included only the elements thought to be essential, but the drawing brings out at a glance the distinction between the physical (sound waves), physiological (phonation and audition), and psychological parts (word-images and concepts). Indeed, we should not fail to note that the word-image stands apart from the sound itself and that it is just as psychological as the concept which is associated with it. "

"The term 'emoticons'—short for 'emotion icons'—refers to graphic signs, such as the smiley face, that often accompany computer-mediated textual communication. They are most often characterized as iconic indicators of emotion, conveyed through a communication channel that is parallel to the linguistic one. In this article, it is argued that this conception of emoticons fails to account for some of their important uses. We present a brief outline of speech act theory and use it to provide a complementary account of emoticons, according to which they also function as indicators of illocutionary force. More broadly, we identify and illustrate three ways in which emoticons function: 1) as emotion indicators, mapped directly onto facial expression; 2) as indicators of non-emotional meanings, mapped conventionally onto facial expressions, and 3) as illocutionary force indicators that do not map conventionally onto a facial expression. In concluding, we draw parallels between emoticons and utterance-final punctuation marks, and show how our discussion of emoticons bears upon the broader question of the bounds between linguistic and non-linguistic communication."
