Am I a Cyborg? Are You?

The term "cyborg" is being used in a surprising variety of ways. Some authors argue that the human being as such is-and has always been-a cyborg (Clark, Sorgner). Others see the term as describing what is peculiar about humanity in the present era (Haraway, Case). Still others reserve it for some current forms of human existence (Moe and Sandler, Warwick). Lastly, Clynes and Kline, who originally introduced the term, use it as referring to possibilities of the future. In the present paper, I examine what is at stake in this disagreement. I highlight that the different uses of the term "cyborg" can be seen as being based on one and the same conception of the human being and its relationship to technology, namely, the idea that human-machine hybridization is a gradual, longstanding and ongoing process. I explain how, arising from this common idea, the existing uses of "cyborg" diverge. I then raise the question of which of these uses is the most plausible or useful.
