Concept algebra is very weak, because it has
only propositions and some connectives.

Just read the following piece of text (these days):

"Peirce's calculus of relations has been criticized for remaining
unnecessarily tied to previous work on Boolean algebra and the
equational paradigm in mathematics. It has been frequently claimed
that real progress in logic was only realized in the work of Frege and
later work of Peirce in which the equational paradigm was dropped and
the powerful expressive ability of quantification theory was
realized."
