This development has largely been fueled by an increasing dissatisfaction to what has earlier been taken to be a straightforward outcome of โlogical pluralismโ or โmethodological diversityโ. These phrases appear to reflect the everyday chaos of our academic pursuits rather than any genuine attempt to clarify the general principles underlying the miscellaneous ways in which logic appears to us.
