First, you need a list of prefixes (e.g. poetry, metaphysics). Then, iterate over that list and unite prefix_*.pdf into prefix.pdf.

Here we generate the list of prefixes by searching for files ending with _NUMBER.pdf and removing that last part. This assumes that filenames do not contain linebreaks.

printf %s\\n *_*.pdf | sed -En 's/_[0-9]+\.pdf$//p' | sort -u |
while IFS= read -r prefix; do
  pdfunite "$prefix"_*.pdf "$prefix.pdf"
done
