Introduction: Routes in Relevant Logic

Part of the Reason and Argument book series (REAR, volume 1)


It is an exciting time in logic, it is a dull and irritating time in logic; it is the best of times, it is the worst of times; it is an age of relevant logical innovation, it is an age of conformity, oppressed by restrictive practices under the dominant logical paradigm; it is a season of brilliant shafts of light, it is a season of classical darkness; it is a spring of hope, it is a winter of despair; we have everything before us, we have nothing before us; we relevantists are all going direct to Heaven to inspect the keys of the Universe and what they open, we are all condemned to go direct the other Way — in short it is a time so far like other periods of major logical revolution that some of the noisiest anti-authorities insist upon it being received, for good or evil, in the superlative degree of comparison only.1
