The Fundamental Principle of Analysis

...[I]f the fear of falling into error sets up a mistrust of Science, which in the absence of such scruples gets on with the work itself, and actually cognizes something, it is hard to see why we should not turn round and mistrust this very mistrust. Should we not be concered as to whether this fear of error is not just the error itself? Indeed, this fear takes something-- a great deal in fact --for granted as truth, supporting its scruples and inferences on what is itself in need of prior scrutiny to see if it is true. To be specific, it takes for granted certain ideas about cognition as an instrument and as a medium, and assumes that there is a difference between ourselves and this cognition. Above all, it presupposes that the Absolute stands on one side and cognition on the other, independent and separated from it, and yet is something real; or in other words, it presupposes that cognition which, since it is excluded from the Absolute, is surely outside of the truth as well, is nevertheless true, an assumption whereby what calls itself fear of error reveals itself rather as fear of truth.

~G.W.F. Hegel
