How We Think: Digital Media and Contemporary Technogenesis argues that human thought is not separate from media, but formed through, with and alongside the technologies that organize perception, reading, memory and scholarly practice. N. Katherine Hayles examines how the humanities are being transformed by digital media, not simply because scholars now use computers, databases, web searches or online publication, but because these tools reshape habits of attention, cognition, collaboration and knowledge production. The book’s central concept is “technogenesis”: the coevolution of humans and technics. Digital environments alter how people read, write, research and teach, while human practices simultaneously redirect what technologies become. Hayles contrasts print-based scholarship with digital humanities, showing that the age of print is losing its invisible authority as the default model for thought. She proposes Comparative Media Studies as a bridge between close reading, hyper reading and machine reading, arguing that each mode has distinct cognitive and interpretive value. Close reading cultivates depth and sustained attention; hyper reading responds to information overload through scanning, linking and selection; machine reading uses algorithms to detect patterns beyond human scale. Rather than lamenting distraction, Hayles asks how pedagogy and research can combine these modes critically. The book also studies databases, telegraph code books, spatial history, electronic literature and experimental novels to show that cognition is distributed across humans, machines, codes, interfaces and material supports. Its strongest contribution is to redefine thinking as an embodied, extended and media-specific process, where attention becomes the scarce resource and collaboration replaces the solitary model of scholarship. The conclusion is that digital media do not destroy the humanities; they force them to rethink their methods, institutions and publics, opening a more hybrid, technical and reflexive understanding of how knowledge is made.
