Fallibilism is a doctrine according to which each and every one of people’s allegations for reality is misleading, wrong, or susceptible to error. Although it may look very similar at first, Fallibilism shouldn’t be mistaken for Scepticism (especially in its extremes where it tends to deny the possibility of knowing the reality).
For a fallibilist, absolute security is an unattainable ideal for a researcher. Yet there are numerous objects that we know with certainty.
Still, one of the founders of semiotics – Charles Peirce was a radiant defender of the fallibilism’s doctrine.
