In the case of Lincoln’s famous statement, in which he uses the metaphor of “swapping horses while crossing a stream” for replacing the President, two methods of the reconstruction currently under consideration are irst introduced: metaphor as an argument by analogy in the “standard” model of pragma-dialectics and as a presentation device in pragma-dialec- tics extended by the concept of strategic maneuvering. Then, a competing reconstruc- tion of Lincoln’s metaphors in the Argumentum Model of Topics (AMT) is presented, which is based on the development of the pragma-dialectical concept of material and procedural starting-points. Lincoln’s argument is reconstructed as a complex argu- ment, where the metaphor igures as a sub-argument using locus from analogy that is used to support a datum in the main branch of the argument. This reconstruction is compared with previous solutions, and beneits of AMT are presented: the transpar- ency of the captured argument structure and a more complex view on the strategic function of metaphor. For research of the strategic function of metaphor, the concept of keyword and the results of the research of the interaction between datum and en- doxon are used. It is proposed to consider metaphor as a lexical unit used to identify a keyword. Keywords: AMT model, endoxon, metaphor, pragma-dialectics, strategic maneu- vering.
