This paper reflects on the teaching of science fiction texts to first-year engineering students at the University of the Witwatersrand as part of a Critical Thinking course that uses literature as a vehicle through which to develop competence in critical literacy and communication. This course aims to equip engineering students, as future intermediaries between science and society, with the ability to fulfil this role in both the contemporary global world and South Africa more specifically through the imaginative inhabitation of divergent subject positions afforded by literary texts. Science fiction encourages students to engage imaginatively with various societal ideas, constructs and possibilities. One of the principles of the course is that reading facilitates empathic responses, challenging readers to inhabit unfamiliar subject positions. In this way, the teaching of science fiction aims to develop self-reflective and critical learning practices, wherein engineering students grapple with the ethical ramifications of extrapolated known science in a South African context.
