Within the larger field of the (post-)humanities, the terms 'posthumanism' and 'posthuman' have been difficult to determine. A quick Google search on any of these words will list many websites which don't seem to tackle the topics which are in discussion here, such as animality and the limits and limitations of what has been called 'humanity'. Many people seem to consider the prefixes 'post' and 'trans' as interchangeable, and therefore use 'posthumanism' and 'transhumanism' as synonyms, when, in fact, they must be conceptualized as two very distinct lines of thought.
