In this work, we attempt to circumvent three (more or less) equivalent negative results. These are (i) non--axiomatizability (by any finite schema) of the valid formula schemas of first order logic, (ii) non--axiomatizability (by finite schema) of any propositional logic equivalent with classical first order logic (i.e., modal logic of quantification and substitution), and (iii) non--axiomatizability (by finite schema) of the class of representable cylindric algebars (i.e, of the algebraic counterpart of first order logic). Herein, two finite schema axiomatizable classes of algebras are shown that contain as a reduct the class of representable quasi--polyadic algebras and the class of representable cylindric algebras, respectively. We present positive results in the direction of finitary algebraization of first order logic without equality as well as that with equality. Finally, we will indicate how these constructions can be applied to turn negative results (i), (ii) above to positive ones.
