This article offers the interesting notion that in medieval time, people “extended their selfhood” by creating natural born cyborgs composed from a synthesis between human and Christ. This symbiont was a “more developed, more advanced, and more powerful version of the [individual's] existing self.”
Generally, “medieval ascetic practices such as fasting, meditation on the body of Christ, and contemplation” are seen as a way for a person to reject the physical for the spiritual. However, a cyborgian (if such a word exists) perspective views these practices as “highly developed forms of distributed cognition that combine body, mind and external technologies in a continuous and semi-automatic feedback loop.”
I personally take a broad perspective regarding the definition of cyborg. From this vantage point, humans have long been cyborgs; since the time when we were fist able to act through a tool, using and perceiving this external piece of technology as an extension of ourselves. Such tools are, of course, not limited to physical devices, language being an obvious example. Taking this one step further, the ideas and concepts that exist in language can also be considered as tools.
Religion is a conceptual tool. A man-Christ (or man-any religion) combination can give rise to cyborg if the integration happens at the appropriate level – as an extension of self.
After reading the fascinating history of coffee and tea I think it is fair to classify these substances as enhancers, and as a technology (at least in the way that we often use them). With that in mind, we could say that drinking coffee and tea is one of the ways in which we are cyborgs.
