Book excerpt: If thinking can be fast or slow, metaphorical thinking can be fast and slow too. But metaphorical thinking does not occur as often and in the ways that many metaphor scholars today think. Slow metaphorical thinking does mean, however, that we can exert more control over metaphor than has previously been acknowledged. We can even offer resistance to metaphor. Deliberate Metaphor Theory (DMT) claims that there is an essential processing difference between non-deliberate and deliberate metaphor use which can explain all this. This book is the first full account of the DMT model for metaphor comprehension. It presents explicit conceptualization and formal operationalization, and is based on a well-known cognitive-psychological model for all utterance comprehension in discourse. The original three-dimensional model of DMT is here refined into a four-dimensional model, which reveals new research questions and discoveries about the use of metaphor. The book brings together numerous cognitive-scientific insights into metaphor. It has a high degree of interdisciplinary accessibility to all students of metaphor, whether master students, PhDs, post docs, or established academics.
