 The precise historical origins of 14th century theories of consequence are still debated among scholars. What we know is that, at the beginning of the 14th century, treatises and chapters bearing the title De consequentiis and similar titles began to appear. Why then, and not before? Naturally, the subject itself, that is, the logical/inferential relations between sentences, had been extensively discussed by earlier authors, as we have seen. But no treatises or chapters were specifically dedicated to the topic or bore such titles before the 14th century.
