The Quartodeciman controversy of the second century A.D. had to do with the date on which the resurrection of Christ ought to be observed. Churches in Asia Minor preserved the custom of tying this observance to the date of the Passover, whatever day of the week that happened to fall on. The Roman practice was instead to observe it on a Sunday, since that was the day Christ was resurrected. The eastern practice was defended by St. Polycarp, who appealed to the authority of none other than his teacher St. John the Apostle. Pope St. Anicetus tried unsuccessfully to convince Polycarp to adopt the Roman practice, and they agreed to disagree.

Most philosophers have at least a vague awareness of this. For instance, they know from standard textbooks that traditional and modern logic differ in their interpretation of categorical propositions, the repercussions this has for their understanding of the square of opposition, and so forth. They know that there has been much debate in contemporary philosophy over the status of modal logic, not to mention even more exotic systems like quantum logic. They may be at least dimly aware that systems of logic were developed in the history of Indian philosophy that differ from those familiar to Western thinkers. And so on.
