Although scholars generally agree that satire cannot be defined in a categorical or exhaustive way, there is a consensus regarding its major features: satire is a mode, rather than a genre; it attacks historically specific targets, who are real; it is an intentional and purposeful literary form; its targets deserve ridicule on the basis of their behavior; and satire is both humorous and critical by its nature. The specificity and negativity of satire are what separates it from comedy, which tends to ridicule general types of people in ways that are ultimately redemptive. Satire is also rhetorically complex, and its critiques have a convoluted or indirect relation to the views of the author. Satire’s long history, which is not straightforwardly linear, means that it is impossible to catalogue all of the views on it from antiquity through to modernity. Modern criticism on satire, however, is easier to summarize and has often made use of ancient satirical traditions for its own purposes—especially because many early modern theorists of satire were also satirists. In particular, modern satire has generated an internal dichotomy between a rhetorical tradition of satire associated with Juvenal, and an ethical tradition associated with Horace. Most criticism of satire from the 20th century onward repeats and re-inscribes this binary in various ways. The Yale school of critics applied key insights from the New Critics to offer a rhetorical approach to satire. The Chicago school focused on the historical nature of satirical references but still presented a broadly formalist account of satire. Early 21st century criticism has moved between a rhetorical approach inflected by poststructural theory and a historicism grounded in archival research, empiricism, and period studies. Both of these approaches, however, have continued to internally reproduce a division between satire’s aesthetic qualities and its ethical or instrumental qualities. Finally, there is also a tradition of Menippean satire that differs markedly in character from traditional satire studies. While criticism of Menippean satire tends to foreground the aesthetic potential of satire over and above ethics, it also often focuses on many works that are arguably not really satirical in nature.
Globalization and global travel have existed for centuries. It is over the past century in particular, however, that travel has become truly global, in the sense that most and not just some travel can in some way or other be said to globalized. Indeed, with the invention and spread of new technologies of mobility (like jet travel), and new technologies of information (like the internet), as with the increasingly invasive impact of human activity on the planet at large (like global warming), it is difficult to conceive of travel in the 21st century that is purely “local.” Travel in the age of globalization, then, is at one and the same time both more widespread yet also more irrelevant than ever. As humans, goods, and information move around in ever-increasing quantities, and at ever-greater speed, it seems that mobility is at an all-time high in human history. On the other hand, as a rising number of people and places are interlinked through ever-faster travel and various forms of communication technologies, the local and the global are becoming harder and harder to distinguish. In this, travel writing has faced a range of challenges that are both old and new. With contemporary travel writers facing a global reality that is very different from the colonial legacy of a traditionally Eurocentric genre, travel writers in the age of globalization have been forced to radically reconsider the itineraries, the destinations, the purpose, and the identity of the traveling subject. Traditionally defined as a white (European) male, the global traveler of the 21st century can take on many forms in terms of race, gender, sexuality, and nationality. At the same time, however, a large number of contemporary travel writers have found it hard to break with the mold of old, desperately continuing to pursue the exotic adventure and the untouched “otherness” of the blank spaces of a map that, in the age of Google Earth, satellite navigation, jet and space travel, global warming, and an explosive growth in human population, are no more.
