Can a culture study its own knowledge? Yes, according to sociologist David Bloor. More than that: it is vital that we can look at our own scientific knowledge scientifically. Otherwise, there would be an “irony at the very heart of our culture. […] it would mean that science could not scientifically know itself.” Speaking of irony: 2400 years before Bloor said this in 1976, Socrates supposedly saw himself confronted with a very similar question while talking to a certain Charmides. For reasons wholly different than Bloor’s, Charmides and his caretaker Critias defend the position that science can be applied to itself – that there is a ‘meta-science’ through which we know knowledge.
